Turning the PlateRunner On
When filling the tank with the recommended
developer, use a container, siphon hose, or funnel that
allows you to pour the chemicals in the correct tank.
Avoid splashing developer on the mechanical and
electrical components. Clean up any spilled developer
immediately.
Some developing fluids foam easily, pour them
carefully to avoid excessive foaming.
Wear protective glasses and gloves.
1. Check that the Developer Tank Drain Valve is shut
off and the handle is horizontal. Then pour 15 liters of
developer into the Developer Tank.

6. 6
2. Connect the PlateRunner to the electrical service and
turn it on (the red power switch pointing to “1”).
3. Raise the Top Cover and set the Main Cover Switch in
Service Mode
4. Turn on the water supply.
5. Wait until the processor is Ready.
6. Activate a processing cycle by holding a plate over the
Input Detector for five seconds.
7. When a processing cycle starts, wait a few seconds
for the water to flow out of the spray bars. Observe
the direction and strength of the Pre-wash and Rinse
spray.
The Pre-wash sprays are directed on the brush.
The Rinse spray is directed onto the front respective
roller. The inside top surface of the roller should
be wet, but not flowing over the top of the roller.
Directing it down into the tank will reduce the time
that the plate is rinsed, and may cause foaming.
8. Adjust the flow rate using the water supply valve on
the hose. The jets should be even along the bar and of
moderate force. While the water is running, look into
the tanks and make sure that they are draining.
9. Look at the Developer Tank and locate the two
depressed drain slots located at the top of the tank
front wall. These serve to drain excess developer fluid.
For proper operation, an equal amount of developer
waste must drain from both the right and left slots.
10. Add developer so that it reaches and trickles through
the drain slots.
11. Observing the two drain slots, adjust the right and left
pairs of the PlateRunner’s legs until the developer
drains equally from each slot. When adjusting the left
side, turn both left feet an equal number of turns in
the same direction. Similarly, when adjusting the right
feet, turn both right feet an equal number of turns.
12. Make sure all the feet are in contact with the floor and
the processor cannot be rocked.

7. 7
13. Verify the drain is free and clear and that no effluent is
escaping.
14. Check that the filter housing is firmly seated.
15. Check all the fittings, tanks, and seals for leaks.
16. Lower the Top Cover.
Start Up
The main power switch is located at the front below the
Input Tray. The main switch activates all the sections
of the PlateRunner Processor: the feed system, heaters,
recirculation pumps, dryer, display, brush, etc. After a few
seconds, the Status Window will appear in the display,
indicating the status of the different sections of the
Processor.
Turn on the water supply.
To verify the temperature is set correctly, attach one
temperature strip on the back of the platetemperature strip on the back of the platetemperature strip on the back near each
corner , and one temperature strip near the center of the
plate. Process it as normal and check the temperature
strips afterward to verify it is operating at the correct
temperature.
◊◊◊
Status Display
The Status Display shows the temperature of the Preheat
Sections (Pre1 and Pre 2), Developer Temperature Section
(dev), and the Development Time. The number in the
upper left corner shows what plate type the system is set
up for.
The value displayed will be close to the set points. If the
temperatures are not close enough to the values set, the
“Ready” line will be replaced with “Waiting for temp.”
Wait for “Ready” to appear.Wait for “Ready” to appear.W

Control Panel

8. 8
Description of Control Panel Keys
The four keys below the display are used to set the
PlateRunner Functions. These are illustrated and described
below.
MENU KEY Opens the main menu.
When in the Menu Tree, it brings up the previous
menu.
UP KEY Changes item selected on the
menu shown by the cursor and increases the selected
value. When pressed prior to any other key it brings
up the Plate Type menu.
DOWN KEY Changes item selected
on the menu shown by the cursor and decreases the
selected value. When pressed prior to any other key it
selects the Standby Parameters menu.
ENTER KEY Confirms the parameter
or value selected. If pressed before any other key, it
opens the Controls Menu.
Using the control keys takes the operator to the various
menus where the parameters can be controlled. Thinking
of the menu as a horizontal tree extending to the right, the
ENTER key steps to the right through the menu options
and the MENU key retraces those steps.
In describing the menu options, and how to select and set
values, the description is accompanied by an illustration.
In each case the starting display is on the left, the action
taken is in the middle, and the resulting display in on the
right.
Accessing the Controls
Pressing the far right ENTER key accesses the Plate
Counter, Heater Control, and System Reset.

9. 9
The left panel labeled DISPLAY is the starting menu, the
middle panel labeled KEY specifies which key to press,
and the resulting display is on the right.
Setting the Plate Counter
With the cursor pointing to Counter, press the ENTER
to bring up the Plate Counter Menu. The number shown
is the number of plates processed since the counter was
reset. The count can be reset to zero by pressing ENTER.
Activating the Heaters
The heaters can be turned on and off. There are two
pre-heat panels, Pre-heat 1 and Pre-heat 2, the Developer
Heater, and the Dryer for the gum station. Move the cursor
to On/Off Heaters using DOWN. Select that heater with
ENTER.
The cursor before PRE-HEAT shows which heater is
active. Pressing the ENTER KEY will toggle that heater
ON and OFF.
The DOWN and UP keys move the pointer to the desired
heater.
To turn the Developer Heater on, press the DOWN
key twice which moves the cursor down two lines to
Developer.

10. 10
Pressing the ENTER key will now toggle that function on.
A similar sequence will turn the other functions on and
off.
Resetting the System
When a plate is placed on the Input Tray, and detected by
the Input Detector for more than five seconds, a sequence
of events is initiated. The system comes out of standby
and starts the operational sequences required to process
the plate.
If it is necessary to reset the system before the cycle
is completed, the operator may do so from the Control
Menu. A reset is only accepted once the plate is past the
Pre-heat Section.
Select Reset by moving the cursor to it and press the
ENTER key. After Resetting, the Display will briefly show
“Complete”. If the plate is in the Pre-heat Section, and
the Reset is not accepted, an Error message will briefly be
displayed.
Accessing the Functions
The four groups of parameters to access and set are found
on the Function Menu. They are reached through the
PRE-HEAT, DEVELOPER, GUM-DRYER, and SPEED
PROGRAMS menus.
To reach them from the Status Display press MENU.
The rest of this section will describe how to access and set
the processor parameters.

11. 11
Pre-Heat Parameters
Two independent heaters are used to complete the plate
exposure by uniformly preheating the imaged plate.
The two heaters are independently controlled and their
temperature setting are accessed from the Main Menu by
placing the pointer on PREHEAT and pressing MENU.
As these are controlling the temperature of the heaters,
the values used will be higher than those desired for the
plates.
Setting Pre-Heat Temperature
Pressing ENTER when the cursor is at PRE-HEAT
accesses the functions Pre-heat 1, Pre-heat 2, and Timing.
Using UP and DOWN, place the pointer on the desired
Pre-heat Panel. Pre-heat 1 is shown as an example, and
select with ENTER.
To deliver more heat to the plate, adjust the temperature
setting, in Centigrade; using DOWN reduces the heat.
Press ENTER to enter the value.
To return to the previous menu, PRE-HEAT, press
MENU.
NOTE: Pressing MENU repeatedly will retrace your
steps back through the Menu Tree until the Status
Display is reached.
A similar process is used to set the temperature for the
other heater. A nominal setting for Preheat One is 208
degrees Centigrade (C) and 200 C for Preheat Two.
Chemical settings will change based on the chemicals and
plates being used.

12. 12
Setting Timing
To assure an even temperature along the plate as well
as across, the heater panel temperatures are modified as
the plate progress through. The temperature profile is
controlled by a few parameters set at the factory.
NOTE: Only adjust these settings when directed to by
your service representative.
To access them from the PRE-HEAT Menu, below, scroll
the pointer down to Timing and select with ENTER to
bring up the Timing Menu.
Although called the Timing Menu, the values use both
time and plate length. This assures that as different plate
sizes and developing times are used, the heating profile
delivered to the plate will remain constant.
Delay is the delay from when the Input Detector senses
the plate until the control algorithm starts to cycle the
heaters. The heating cycle operates as the plate is passing
through the Pre-heat Section, Active Length. Inactive
is how long the heater is off and Active is how long the
cycle operates.
The four algorithm windows are shown below. Access
each from the Timing Menu by scrolling the cursor
(asterisk), using UP and DOWN, and selecting with
ENTER.
Again only change these at the direction of your service
representative.
The values in each menu are changed using UP and
DOWN.

13. 13
Use MENU to return to the previous display.
Developer Parameters
To assure optimum processing, the developer temperature
is maintained at the manufacturers recommended value.
As each plate processed reduces developer strength
and removes a small amount of fluid, the developer is
automatically replenished. The amount of developer added
each time a plate enters is specified in milliliters.
To access these parameters, set the pointer to
DEVELOPER on the Function Menu and select with
ENTER.
Setting Developer Temperature
Selecting “Developer Temp.” with ENTER brings up the
following display. The desired temperature value is set
with UP and DOWN. The plate manufacturer specifies the
exact value set.
The PlateRunner’s Developer Heating System will
automatically heat the developer to that temperature.
If the developer temperature is above the desired value
due to a hot environment, the optional Chiller may be
required. It one of these options has been installed, the
temperature will be heated or cooled to maintain the set
value.
Setting Developer Replenishment
Returning to the previous menu, set the pointer to Auto
Replenish to access the amount of developer that is
replenished when a plate enters.
As the amount required depends upon plate size, use UP
and DOWN to set the value in milliliters per plate. If you
do not know what that number is see the EXAMPLE.

14. 14
It is very important that the developing tank remains full
during use, and that a small amount runs over the two
waste slots and into the waste receptacle. If this does not
happen as a series of plates are processed, increase the
dose until developing solution consistently trickles over.
EXAMPLE:
The plate manufacture’s replenishment recommendations
will likely be in milliliters per square foot (ml/ft2)
or square meter of plate (ml/m2). The PlateRunner
replenishment rate is set in units of milliliters per plate
processed.
To get the number for your plate, your average plate area
must be multiplied with the manufacture’s recommended
replenishment dosage rate. For example, if your plate
area, found by multiplying the plate dimensions, is 0.5
meters, and the recommended dosage rate is 10 milliliters
per square meter, you would set the volume to 5 ml in the
menu above.
Manually Replenishing Developer
When the developer level is low, it can to be added
from the control panel. From the Developer Menu select
Manual Replenish.
Operate the pump using UP. It will continue to operate
while UP is pressed. With the cover raised, look at
the processor slots to determine when the developer is
trickling over them.
Gum-Dryer Parameters
Gum is applied to each plate as it passes through the
rear section of the processor. After the gum station the
plate passes beneath the Dryer where heat is used to
dry the gum. The time that gum is applied and the dryer
temperature are set from the control panel.
To access these parameters from the Function Menu set
the pointer to GUM-DRYER and select with ENTER.
Also located on this menu is a manual feed function for
applying gum.

15. 15
Setting Gum Volume
Set the pointer to Gum Dose, and press ENTER to
access the Gum Application Menu where the Gum Pump
operation duration is set. As the in-line valve limits the
pump flow rate, the time set needs to be determined by
experimentation.
Set the value using UP and DOWN.
Setting Gum Dryer Temperature
After being gummed, the plate is dried with a heating
lamp. The temperature of the dryer is set by placing the
pointer on Dryer Temperature and selecting with ENTER.
Set the value using UP and DOWN, select with ENTER,
and return with MENU.
Manually Adding Gum
Set the pointer to Manual Replenish, and using ENTER,
bring up the Manual Gum Menu. Pressing UP manually
adds gum while the key is depressed.
Speed Parameters
The development time and rotational speeds of the Pre-
wash and Developer brushes are set from the SPEED
menu.
To access these parameters on the Function Menu, set the
pointer to SPEED and select with ENTER.

16. 16
Setting Developer Time
The development time is a function of the transport speed
and length of the developer bath. Length of the developer
bath is kept constant by paying attention to processing
leveling at installation, and developer level daily.
To set the time of development, place the pointer on
Development Time and use ENTER.
Use UP and Down to set the development time to the
manufacturers recommended time for the developer
temperature set. Return using the MENU key.
Setting Pre-wash Brush Speed
The rotational speed of the Pre-wash Brush is set for
optimal processing. To change the speed, place the cursor
on Pre-wash Brush and press ENTER. The values entered
are a percentage of the maximum speed.
The value is adjusted with UP and DOWN.
If some protective coating adheres to the plate after
brushing, increase the speed. Refer to Chapter 6 for
Troubleshooting tips.
Setting Developer Brush Speed
The rotational speed of the Developer Brush assembly is
set for optimal processing. To change the speed, place the
cursor on Developer Brush and press ENTER. The values
entered are a percentage of the maximum speed.
The value is adjusted with UP and DOWN.

17. 17
Again, if some unexposed emulsion remains on the
plate after brushing, increasing the speed in some cases
can resolve the issue. Refer to Chapter 6 for more
Troubleshooting tips.
Standby Parameters
To assure optimal processor performance the PlateRunner
enters a standby mode when no plates are being processed.
During the standby mode the rollers turn slowly, the
developer brush turn intermittently, the developer pump
continues to run and the developer is periodically added.
The values for when the PlateRunner enters Standby,
the amount and frequency of developer addition, can be
changed.
The Standby Menu is reached from the Status Menu by
pressing DOWN.
Setting Standby
A length is used tA length is used tA length is used o program when you want the processor
to go into standby mode. The processor is approximately
1,500 millimeters long. As you want the processor to go
into standby just after the plate exits, set the value to 1550
mm.
On the Standby Menu, place the cursor on Processor
Length and press ENTER.
Use UP and DOWN to change the value, and ENTER to
accept it. If you will be feeding it plates frequently and do
not want it to go into standby, set the value higher. Press
MENU to return to the previous screen.
Setting Standby Developer Volume
The amount of developer added during a standby
replenishment is set from the Standby Volume Menu.
Place the cursor before it and ENTER.

18. 18
The amount specified is dependent on the plate
manufacturer’s recomendations, machine usage and
environmental conditions. For example, in a hot dry
setting, the evaporation is far greater than that experienced
in cold and wet climate. Determine the amount based on
your observed usage and how much fluid must be added
each morning.
The criteria used in setting this, and Developer Timing, is
that the developer must trickle evenly over the two drain
slots.
Setting Standby Developer Timing
Frequency of developer addition during standby is set
from the Standby Interval Menu.
Again, the frequency is dependent on the climate so use
both replenishment timing and volume to find the correct
balance for long-term use of the developer. The correct
amount is determined by monitoring the pH and level of
the developer bath. As the seasons change, the values will
also change.
Use UP and DOWN to enter the desired value.
Standby Gum Timing
When the plate enters the processor, gum is applied to
the rollers. As it requires a short time to reach an optimal
spread and thickness on the plate, the timing of the Gum
Dose can be adjusted. If the dose appears to be applied too
soon, the point at which it occurs can be set further into
the machine.
A setting of zero millimeters (0.0 mm) the gum would be
applied as the plate’s leading edge enters the PlateRunner,
a higher value will apply gum after the plate has entered
the machine and it has moved closer the Gum Section.
Set the pointer to Gum Delay and bring up the Gum Delay
Menu with ENTER.

19. 19
In this example, a value that is closer to the Gum Roller
has been entered. Again, this has to be determined by trial
and error and is dependent on the Gum Dose settings.
Selecting Plate Type
The processing parameters can be set for two plate
thicknesses. For instance, you may process both 6 and 8
mm plates, plate type 01 and 02.
Press ENTER to access the Plate Type.
To change the plate type from 01 to 02, use UP.
Similarly, to change the plate type from 02 to 01, use
DOWN.
Make sure that the plate type, 1 or 2, displayed on
the Status Menu matches the plate type that is being
processed.
Standby Plate Type Parameters
The default plate type is 01. All the parameters that have

20. 20
been entered when a 1 was displayed on the Status menu
are used when a plate is processed.
To enter the parameters for a second plate type, use UP to
select 02, two.
Now return to the Status Menu and set all the processing
parameters described above to those recommended by the
plate manufacturer.
Whenever plate type 02 is selected, it will appear on the
Status Display and the parameters entered for 02 will be
used in processing the plate.
Processing a Plate
You are now ready to process a plate. Look at the Control
Panel and observe that the PlateRunner is in a ready state,
“Ready” on the Status Display, and that all the specified
parameters for your plate type are correctly entered.
Place a plate on the Input Tray emulsion side up.
Center it and gently push it into the rollers. When the
Input Detector is covered for five seconds, or more, the
processing cycle will start. The plate will be drawn into
the PlateRunner and will emerge at the rear ready for
printing.
If the plate is shorter than 38 cm (15 inches) rotate it until
the diagonal length is 38 cm (15 inches) to assure that it
will bridge the gap between the transport rollers.
When a plate is detected a hyphen, –, is added to the right
of PlateRunner P20/24 and Ready disappears.
This shows that a plate is in the Pre-heat Section and
another plate should not be submitted. Shortly before the
system is ready to accept another plate, when all the plate
is in the Pre-heat Section, ‘Ready’ will appear to indicate

21. 21
that the system is ready to accept another plate.
Nominal Operating Values
The processor is pre-configured to work with Xante plates
and Xante chemistry. Remember that some of the values
are climate dependent. Through trial and error the operator
may find other settings that give better results.
◊◊◊
Chapter 3
Setting Brush Pressure
There are three brushes used on the PlateRunner; one in
the Pre-wash and two in the Developer Section. The Pre-
wash Brush removes the plate’s protective cover before
processing. In the Developer Section, two brushes assist
the development by mechanically removing emulsion
from unexposed areas.
The brushes are set at the factory to work with Xante
materials. Their settings need to be checked as the type of
plate and developer changes may require an adjustment.
The procedures for setting these brushes are described
below.
NOTE: Correct brush pressure is critical to optimal
performance of the PlateRunner. Brush pressure must
be adjusted as part of the processor setup procedure.
A 5 and 6 mm Allen wrench, some un-imaged plates,
and one imaged plate are required.
Read through the entire procedure before attempting to set
the brush pressures.

22. 22
Setting the Pre-wash Brush
1. Bring the Processor to operating temperature and
raise the top cover. Remove the side covers of
the processor and put the Main Cover Switch in
Service Mode. Remove the Pre-wash Splashguard
and place it on the input tray to trigger the sensor.
2. Turn off the water supply and remove the
Spraybar. Removing the roller assembly may
make it easier to perform the oeprations.
3. Set the RPM between 110 and 120 (approximately
80% for U.S. configurations). On the front panel,
select SPEED then select PREWASH BRUSH.PREWASH BRUSH.PREWASH BRUSH
The UP and DOWN arrows will allow you to set
the RPMs.
4. Place the Xante Tension Strip under the prewash
brush and adjust the screws on each end of the
brush until the roller barely touches the Tension
Strip. Then increase the pressure by turning the
screw 1/4 turn counterclockwise. Be sure that the
pressure is even across the length of the brush.
Turning the adjustment screws clockwise will
decrease the brush pressure. Turning the screws
counterclockwise will increase the brush pressure.
5. Replace the spraybar, splashguard, and roller
assembly (if removed). Reinstall the side covers
and turn on the water supply.
Setting the Developer Brush
1. Bring the Processor to operating temperature
and raise the Top Cover. Remove the Side
Covers of the processor and put the Main Cover
Switch in Service Mode. Remove the Developer
Splashguard and place it on the input tray to
trigger the sensor.
2. Turn off the water supply and remove the
rollers located before and after the developer
brush rollers. (If the developer tank does not

23. 23
have developer or is a new installation - fill
the developer tank with water to set the brush
pressure.)
3. Set the RPM between 110 and 120 (approximately
54% for U.S. configurations). On the front
panel, select SPEED then select DEVELOPER
BRUSH. The UP and DOWN arrows will allowBRUSH. The UP and DOWN arrows will allowBRUSH
you to set the RPMs.
4. Feed the Tension Strip under the front of the
brush and attach the AccuWeigh scale to the
Tension Strip.While the processor is running, set
the scale’s pressure to 12.5oz. Hold the scale at a
steady point and allow the Tension Strip to feed
under the roller. Adjust the screws on either end of
the brush until the Tension Strip begins to “slip”
at 12.5oz. (or around 355g.). If using water in the
developer tank - set the pressure to 14.5oz. (or
410g.).
Adjust both sides and check the pressure again
after the adjustments are made. Check the pressure
under each side and in the middle (the middle may
be slightly different than the side measurements).
5. The second brush is set similarly, however, the
Tension Strip must be fed from the back of the
brush because of the spin direction of the brush.
Feed the Tension Strip under the back of the
brush while the processor is running and set the
scale’s pressure to 9.5oz. (270g.). Hold the scale
at a steady point and allow the Tension Strip
to feed under the roller. Adjust the screws in
the brush pan, until the Tension Strip begins to
“slip” at 9.5oz. (or around 270g.). For water, set
the pressure to 10.5oz. (or 300g.).
Turning the adjustment screws clockwise
will decrease the brush pressure. Turning the
screws counterclockwise will increase the brush
pressure. The adjustment screws for the second
brush are located in the brush pan, as shown in
the photo above.

24. 24
Chapter 4
Setting Gum Quantity
Gum is applied to the plate after it has been developed and
rinsed. The amount of gum applied is controlled from the
front panel by setting the pump duration, interval, and the
inline Gum Valve that reduces the pump flow rate.
1. To set gum flow, remove the Right Side Cover
and locate the Gum Valve located at the right rear
of the unit. Ideally, the pump duration and valve
will be set so that the gum flow just fills the full
length of the pinch between the rollers without
spilling over and uniformly gums the plate.
2. Set the Gum Valve to its mid-position and activate
the Gum Pump by covering the Input Detector
for a period of five, or more, seconds. Modify the
gum pump timing until the above condition is

Basic Maintenance
At the start of each day, check the developer level. Top off
as required.
Present plates shorter than 38 cm (15 inches) rotated to the
direction of travel so that they bridge the inner spacing of
the nip rollers. Plates shorter than this in the feed direction
may fall between the transport rollers and may be difficult
to recover (some disassembly may be required).
After turning on the processor let it run for at least ten
(10) minutes, or until the control panel indicates “Ready”,
before processing a plate. While the heater panels and
developer solution are heating up the Control Panel will
display “Waiting for temp”
Check the Operating Parameters
When processing plates, periodically check the Status
Window to make sure that the processor is operating
correctly.
Regular maintenance is required for optimal processing

26. 26
daily, weekly, and monthly schedules.
As processor maintenance is essential to good
performance, it is recommended that a log be kept of
user maintenance, processor readings, and service. A
Maintenance Logbook is provided with the processor.
Following Periodic Maintenance are more detailed
procedures for maintaining the rollers, filters, changing
developer fluid, and replacing a fuse.
Daily Maintenance
1. Turn on the water supply and empty the waste
buckets. Check that the drain hose is properly
positioned and the drain is clear.
2. Turn the processor on by turning the red power
switch clockwise to the “1:” position and wait for
READY to appear on the display.
3. Verify that temperature and speed settings on the
machine are set correctly.
4. Raise the Top Cover of the processor. Turn the
Main Cover Switch in Service Mode.
and printing results. Be sure to perform the daily, weekly,
and monthly maintenance procedures. Modify these
schedules at the manufacturers directions, or as your
experience dictates.
Check the water levels in the Pre-wash and Rinse
Sections during operation to make sure that they are
draining properly and the water flow and pressure are not
excessive.
To reduce power and developer usage, we recommend
turning the processor off when it will not be used for
an extended time. However, allow 10 minutes for the
processor to come to temperature before processing the
first plate. Check the developer level. When the processor
is ready the control panel will indicate Ready.
The water supply should be turned off when the processor
is left unattended. Be sure to turn it on when restarting the
processor.
Maintenance
Routine maintenance of the processor is necessary to
assure optimal processing. Below are the recommended

27. 27
5. Initiate a processing cycle by covering the Input
Detector for at least five seconds. Verify that
spray tube nozzles are not plugged with dried fluid
or debris. If so, clean the jet tubes thoroughly.
6. Wipe the rollers as they rotate using a damp
sponge.
7. Looking at the two slots on the developer tank,
refill with developer until it starts to run over
equally from both slots.
It is very important for optimal results that the
developer tank remains filled and developer
trickles over the drain slots.
To assure optimal processing it is recommended that the
developer solution pH be measured. If it does not meet
specifications, take the recommended corrective measures.
Some developers will leave chemical deposits on tanks,
fittings and rollers that are not soluble in water and can
be difficult to remove. These deposits can normally be
removed by soaking them with the developer and wiping
with a sponge. Before turning the processor off, move the
gum roller to a “parked” position to clean.
Weekly Maintenance
Check the developer fluid to make sure that it has not
become too thick due to evaporation, plate emulsion
saturation and needs replacement. Measure the pH and
compare it to the manufacturer’s recommendations.
Correct if necessary.
When the developer fluid is changed, as described under
Monthly Maintenance, change the filter as well.
Turn the processor off by turning the red power switch
clockwise to the “0:” position.
Wear protective eyewear and gloves.
1. To change the filter, place a large bucket beneath
the filter housing.
2. Unscrew the filter housing and drain the filter
canister. Remove the filter from the housing and
discard it and the developer fluid. (See developer
manufacturer’s MSDS and consult with local
agencies for any special instructions.) Rinse the
housing thoroughly with water.

28. 28
3. Insert a new filter and replace the filter housing.
Check that the “O” ring is undamaged and in
place. If necessary, replace it. Do not over tighten.
4. Turn the processor on and check for leaks.
If developer fluid or plate coating has dried
anywhere on the rollers, brush, platens, or covers,
use a damp sponge to clean them.
Monthly Maintenance
It is recommended that in addition to cleaning the
processor, the developer solution should be replaced once
a month. However, depending on processor usage, the
manufacturer may recommend a more frequent schedule.
1. Drain and rinse developer section and wash the
tanks with fresh water until they run clean. Wipe
away any residue. Inspect the brushes and check
for leaks in the tanks.
2. Remove and wash “wet” rollers and splashguards.
3. Replace all fluids and filters.
4. Check transmission gears and lubricate if
necessary.
5. Check chiller fluid level if used.
6. Inspect motor belts for wear.
Periodic Maintenance
Wear protective eyewear and gloves.
1. Open the top and remove the side covers from the
processor.
2. With the processor off, place a 20 liters container
(2 five gallon buckets) under the Developer Drain
Valve and empty the used developer fluid into the
waste bucket. After the processor has drained,
turn on the system for ten seconds to pump out the
remaining fluid.
DO NOT allow the processor to run more than ten
seconds as this will burn out the pumps. DO NOT turn
the processor on until you have replaced the developer
fluid.
3. Replace the filter as described in this manual.
4. Remove the three spray tubes and rinse them
clean with warm water. Remove any residue with
a sponge.

29. 29
5. Remove all of the accessible roller sets
sequentially, three through nine, from the
processor by pulling equally up on both supports
in the directions shown in Figure , below. Note
their location, as they must be returned to the
same place.
6. Keep the roller pairs assembled. After lifting them
out, do not let the support bushing separate from
the roller end.
7. Clean the rollers under warm, running water and
use a wet sponge to remove any debris.
8. Using a sponge with warm water, clean all tanks
thoroughly. Remove all loose debris in the tanks,
and scrub any accessible residue adhering to the
walls and floor of each tank.
9. Inspect the brush for residue and uniformity.
Remove any debris or residue.
10. Put 15 liters of recommended developer solution
into the developer tank.
11. Replace each roller pair to its assigned location in
the processor.
12. Replace the spray bars with the spray directed
down.
13. Turn the processor on.
14. Activate a processing cycle by placing a plate
over the Input Detector for more than five
seconds. Direct the flow of the pre-rinse down and
the two wash bars onto their respective rollers.
Make sure that the water does not flow over the
top of the roller.
15. Top off the developer solution using the drain
slots as your guide.
16. Make sure that there are no leaks.
17. Replace the top and side covers.
It is suggested that the floor, and waste receptacles,
beneath the PlateRunner be cleaned.

30. 30
Cleaning the Rollers
The rollers in the PlateRunner should be wiped down
daily. They also require periodic, thorough cleaning.
Follow this procedure to clean the rollers:
1. Turn off the PlateRunner and unplug it.
2. Open the top and remove the side covers from the
processor.
3. Note the location of each roller set and remove
them from the processor by pulling up on both
supports.
4. Keep the roller pairs assembled. Do not remove
the rollers from the end supports.
5. Clean the rollers under warm, running water and
use a sponge to remove any residue.
6. Re-insert the roller assemblies into their assigned
slots.
7. Plug the PlateRunner in.
Removing the Brushes
Lifting the Brushes Assembly straight up removes them or
their location as seen below.
You need to be cautious when lifting as you should apply
the strength in the same direction and have the set levelled
all the time to avoid any damage.
Replacing the Filter
The developer filter is at the rear underside of the
PlateRunner.

31. 31
Periodically the filter needs to be replaced. This is best
done when changing the fluid. We recommend changing
filters every time the developer fluid is changed. The filter
cartridges are 25.4 cm long (10”) and are available from
Xante.
Wear protective eyewear and gloves.
1. Place a large bucket beneath the filter housing.
2. Drain the filter canister.
3. Unscrew the filter housing and empty the
developer fluid into the bucket. Remove the filter
from the housing.
4. Dispose of the used filter cartridge and developer
fluid. (See developer manufacturers MSDS
and consult with local agencies for any special
instructions.) Rinse the housing thoroughly with
water.
5. Insert a new 10” long filter into the housing.
6. Check that the “O” ring is undamaged and in
place. If necessary, replace it.
7. Replace the filter housing in the support,
tightening it by hand. Do not over tighten. Close
the drain valve.
8. Raise the Top Cover and turn on the processor.
9. Check that the filter housing does not leak.
10. Observing the developer tank drain slots, top off
the developer solution from the control panel
using the manual replenishment function.
Changing Developer
Recharging of the developer fluid should be done on the

32. 32
schedule recommended by the plate manufacturer. To
replace the developer:
Wear protective eyewear and gloves.
1. Raise the Top Cover and place a 20 litres
container (five-gallon waste bucket) under the
developer tank drain valve.
2. With the processor off, drain the developer fluid
into the waste bucket. After the processor has
drained, turn on the system for ten seconds.
DO NOT allow the processor to run more than ten
seconds as this may burn out the pumps. DO NOT
turn the processor on until you have replaced the
developer fluid.
3. Clean the developer rollers.
4. Replace the developer filter.
5. Add 15 liters of the recommended developer
solution.
6. When filling the tank, use a container, siphon
hose, or funnel that allows you to pour the
chemicals in the correct tank. Avoid splashing
developer on the mechanical and electrical
components. As some developing fluids foam
easily, pour carefully to avoid excessive foaming.
7. Turn the processor on.
8. Observing the two drain slots, top off the
developer, as the level will drop due to the filling
of hoses and filter. Use the manual replenishment
system from the front panel.
9. Measure the pH for future reference when the
processor shows ‘Ready’.
10. Dispose of the waste fluids properly. See
developer manufacturer’s MSDS and consult with
local agencies for any special instructions.
Replacing a Fuse
Prior to checking a fuse, turn the PlateRunner off and
unplug it from the power source. The fuses are located at
the front of the PlateRunner under the Input Tray.

33. 33
Access the Fuse Panel by removing the two thumbscrews
and lowering the Electronics Cover.
CAUTION: Check that the PlateRunner is unplugged.
You will see the Fuse Panel to the left of the circuit
breakers.
There are fuses for the PlateRunner motors, pumps, and
heaters. The location of each is shown. To replace a fuse
pull the top the fuse holder forward and remove the spent
fuse. Replace it with the value specified in Fuse Values.

34. 34
Replace the fuse with one of the same rating. The
values are summarized below.

Troubleshooting
PlateRunner Specifications
Use ONLY plate manufacturer specified processing fluids.

35. 35
the number of plates processed and the amount of time
that the developer is exposed to the environment.
If you are processing a lot of plates, the replenishment
rate may be too low. Raise it. If the pH falls while the
system is idle, raise the standby replenisher volume and
frequency.
“Why is the developer level falling below the
drain slots?”
If the developer level falls below that waste slots and is
not reaching the waste bucket, adjust replenishment rates.
If the level falls while you are processing a lot of plates,
raise the replenishment rate. If falls while the PlateRunner
is idle, raise the standby replenisher volume and/or
frequency.
“Why are the plates underdeveloped?”
Check the developer solution, temperature, and the
processing time. If the system is at the right temperature,
and the developer is fresh, increase the development
time. If it is still underdeveloped, raise the developer
temperature.
If there are any jet tubes that are not jetting properly, first
wipe the openings with a sponge before removing the jet
tube for cleaning. This will often clear the obstruction and
allow the jet tube nozzle to function normally.
Developer fluid replacement will be dependent on usage,
and may need to occur more often than once per month.
A tint of emulsion observed over the non-imaged area
of the plate is an indicator that the developer fluid needs
replacement.
Keeping the rollers clean is very important. Be sure to
maintain the developer fluid at the correct level.
Temperature issues can also arise occasionaly. Attaching
temperature strips to the back of a plate before processing
can also help detect some processing issues.
“Why isn’t the processor brush turning?”
If after introducing a plate in the processor the brushes are
not turning, check the fuse. Prior to checking the fuse, turn
the PlateRunner off and unplug it from the power source.
Replace the fuse as described on Replacing a Fuse.
“Why is the developer pH too low?”
Basically, two major factors in maintaining pH level are

36. 36
“Why is there no image?”
Check that the developer is fresh and the processor setting
are correct. Expose a plate to room light for one minute
and process it. If it develops, check the imaging system.
“Why is there emulsion on the unimaged
areas?”
If there is emulsion in the unimaged areas, and the
developer is fresh, lower the developer brush ½ turn.
Check the activity of the developer and its temperature.
Try turning the brush speed up.
“Why do the dots appear scrubbed?”
If the dots appear over scrubbed, raise the developer brush
½ turn.
“Why aren’t the plates cleaned in the pre-
wash section?”
Check the pre-wash brush setting and rinse water flow
rate. If the protective coating is stuck to the plate, increase
the brush pressure. If there is loose residue, increase the
water flow. Check the drainage after adjusting the flow
rate.
“Why isn’t the gum drying after processing?”
Increase the dryer temperature. Do not increase it so that
the plates are too hot to handle.
“Why isn’t the gum evenly applied?”
If there is too much gum, reduce the flow. If there is too
little, increase the flow. If it is not uniformly spread,
adjust the gum delay. Check that the gum is thinned to the
manufacturers recommended ration. If it is still too thick,
increase the ratio of the water.
“Why does the wastewater level rise in the
tanks?”
Check that there are no obstructions in the Pre-wash and
Rinse waste lines, drain, or tanks. Decrease the water flow.
The drain must be located within 1.2 m (four feet) and 61
cm (24 inches) below the processor for correct operation.
“Why isn’t my plate coming out?”
Check that the plate fed into the processor and the power
is on. Open the Top Cover and look for it. When found,
determine why it didn’t complete processing.

37. 37
“Why aren’t the plates going through in a
straight line?”
If the plates do not pass through the processor in a straight
line, open the Top Cover and watch a plate traverse. See
if there is any impediment or debris on the rollers. If it
changes direction at a roller set, remove them and make
sure that the springs are in good working order.
“Why doesn’t “Ready” replace “Waiting for
Temp” on the Status Display?”
Check that the Pre-heat and Developer heaters are
turned on. Check the temperatures entered. Wait for the
temperatures to reach their set points. Determine which
heater is not operating by opening the Top Cover and
measuring the developer temperature and placing your
hand above the Pre-heat Section to determine if it is on.
Check the fuses for the heaters.
“Why are the plates light struck?”
Check that the safelight used conforms to the plate
manufacturer’s specification. Check for light leaks by
placing a plate emulsion on the Entrance Tray for two
minutes before processing.
“Why can’t I get the developer residue off?”
The developer residue is not soluble in water. Use
developer as a cleaning agent. Be sure to wear protective
gloves and eyewear.
