2. HP Scanjet 7400c/7450c/7490c Scanner Setup
A. Troubleshooting installation problems
If you installed the HP Scanjet Scanner and the HP Precisionscan Pro software but you are unable to
scan, try these steps:
1. Make sure the scanner has electrical power. To test this, disconnect the power cord from the
scanner or from the electrical outlet. Then, plug in the power cord once again. The scanner lamp
should come on. After you plug in the power cord, lift the scanner document lid immediately to
verify the lamp is on. Note: the scanner does not have an on/off switch.
2. Make sure the cable connecting the scanner to the PC is firmly connected on both ends. To check,
press each end of the cable firmly into its connector. If you are using USB, make sure that you
are using the USB cable shipped with the scanner. HP cannot ensure the quality standards of
other USB cables.
3. Power down your PC and unplug your scanner. Then first plug in your scanner and then power up
the PC.
4. Check the driver installation.
Win95, Win 98, WinMe, and Win2000 Systems
a) Click on Start -> Settings -> Control Panel, and choose System.
b) Click on the Device Manager tab (on Win2000 first click on the Hardware tab).
c) Check the following entries in the list:
- Controllers: USB controllers or SCSI controllers should list your USB or SCSI card.
- Imaging Device or HP Scanjet Scanners: Double-click to display the scanner model number.
d) If either entry is missing, or if the entries are marked as conflicts (yellow circles and
exclamation points), remove the controller drivers and uninstall HP Precisionscan Pro software
and reinstall it.
Win NT 4.0 Systems
a) Click on Start -> Settings -> Control Panel.
b) Double-click on SCSI Adapters. Windows displays the dialog for the adapters.
c) Verify that a SCSI controller for the attached scanner appears in the list. If the SCSI controller
is missing, re-install the SCSI controller software that came with your SCSI card.
d) Click the plus sign next to the SCSI controller and verify that a HP model number code (HP
######) appears. If no HP code appears, shut down your computer and then try one of the
following solutions:
* look for any bent pins at each end of the SCSI cable, if there are bent pins you may need a
new SCSI cable
* make sure both ends of the SCSI cable are firmly attached to your PC and scanner.
5. Make sure the HP Precisionscan Pro scanning software is installed. If you used the defaults in the
installation program, the software is installed in the following directory: Program FilesHewlett-
PackardPrecisionScan Pro 3.0. If you entered a different location for the software, check the
program group where you installed the HP Precisionscan Pro scanning software. If the software is
not installed, run the Installation Program and install the HP Precisionscan Pro software. (To run the
installation program, run the Setup.exe on the HP Scanning Software CD).

3. B. Freeing up disk space
If you have limited disk space, load only the HP Precisionscan Pro software.
- Use the Custom Install feature of the Install program to de-select all the other software when
installing the software from the CD . Make sure there are not any other software applications
checked except HP Precisionscan Pro.
- NOTE: Not installing Acrobat Reader will prevent you from displaying the HP Precisionscan Pro
User's Manual.
C. Silent installation for HP PrecisionScan Pro software
A Silent Installation allows you to install the HP PrecisionScan Pro software without seeing any of the
dialog boxes normally displayed. When doing a silent install you will not have a choice of where your
software is installed on your machine or the name of the program folder. Your computer may reboot
without asking for your permission. Moreover, you also will not see the license agreement. If you
choose to use this feature you have agreed to the terms and conditions of the license agreement.
To run the PrecisionScan Pro installation in silent mode you will need to pass a couple of flags to the
setup program. You can do this by using a DOS prompt. To run from a DOS prompt, change the
directory to the D:hppspro directory (where D is the drive letter for your CD-ROM). You will need to
execute the following command: setup /s /v/qn (note: there must be a space between setup and /s and a
space between /s and /v/qn, and no other spaces).
D. Administration installation for HP PrecisionScan Pro Software
An administration install simply uncompresses the scanning software files and puts them out on a
network drive so everybody on the network can access them. It does not install the scanning software
but simply copies and uncompresses it so other users can install it from the network and/or so patches
can be applied. The following command line initiates the administration install:
msiexec /a "D:hppsproHP PrecisionScan Pro 3.0.msi"
(where D: is your CD-ROM drive). A series of dialogs should appear that guide you through the
administration install. During this process, you will need to know the network server name and
directory where you want to place your scanning software. If the above command is not recognized by
your system, you will need to run D:hppsproinstmsiw.exe, if your system is NT 4.0, or
D:hppsproinstmsia.exe if you are running from a 95 or 98 system. These executables will install the
Windows Installer engine. Windows 2000 and Millennium ship with Windows Installer engine as part
of the operating system and should recognize the msiexec command. You will also need to manually
copy four additional files: setup.exe, setup.ini, instmsia.exe and instmsiw.exe all residing in the
D:hppspro directory (where D: is your CD-ROM drive) to the directory specified in the dialogs
during the administration install. Note, the correct directory will also contain the HP PrecisionScan Pro
3.0.msi file. The software can now be installed from the network by executing this setup.exe file on the
target computer.
3. HP Precisionscan Pro Software
A. Click and Select (accuracy of Selection Area, finding images on scanner glass)
To get the best results when you use Click and Select, make sure the Preview area is as large as
possible by maximizing the HP PrecisionScan Pro window. For the highest accuracy of the Selection
Area you will need to maximize the window size and Zoom In on the Selection Area
Using Click and Select to Find images on the scanner glass
Click and Select allows you to choose a selection area by clicking on an object. If your images are not
found correctly, try one of the following:

4. * If you are placing multiple items on the scanner glass and they are not detected by the software,
place a white page behind the items.
* If you are scanning material printed on both sides of the paper and it bleeds through, place a black
page behind the original. Magazine pages often bleed through.
B. Printing Issues
Color scanned images that print as black and white on a color printer:
If the resolution for a scanned image is set higher than a printer can handle, the printer may print the
scanned color image as black and white. For example, some printers can print at 600 dpi for black and
white images, and can only print at 300 dpi for color images. If the scanned image is set higher than
300 dpi, the printer may print in black and white. To fix this problem:
* Check the document defaults on the printer. Make sure color printing is enabled. Refer to your
printer manual for more information.
* Change the printer resolution. In HP Precisionscan Pro, click on Print Setup on the Scan menu.
Select the correct printer and click on the Properties button. Click on the Advanced tab of the
Document Properties dialog box. Look for the Resolution setting (usually under Graphics) and
change the resolution to the proper setting for color (for color photos, 200 dpi is optimal). Click on
OK to close the dialog. Print from HP Precisionscan Pro.
MORE NOTES ABOUT PRINTING
* As in other applications, you can not drag and drop from the Preview window to printer icons. Only
files can be dragged and dropped to printer icons.
C. Help System Issues
For best results with the Help system for Precisionscan Pro, install Internet Explorer 5.0 or later on
your PC. Upgrades to earlier versions of Internet Explorer are installed during the Precisionscan Pro
install. If you install an older version of Internet Explorer after you have installed Precisionscan Pro,
run the Repair option for Precisionscan Pro (accessed from the Start menu >>Settings >> Control
Panel >> Add/Remove Programs >> HP Precisionscan Pro 3.0, then click on Add/Remove or Change,
depending on your operating system). This ensures that all older versions of Internet Explorer are
updated to optimize the Help system display.
D. Unlimited Enhanced Resolution
Enhanced resolution is a method of increasing the dpi that you can get in a scanned image. Enhanced
resolution is useful when you want to scan a small original and enlarge it.
HP Precisionscan Pro gives you unlimited enhanced resolution by allowing resolution settings from 12
to 999,999 dpi. With this feature, the only limits to the scanning resolution are your time, hard disk
space, and/or the amount of data that is accepted by other applications.
However, very high resolutions take longer to scan and create much larger files. For example, to
scan an area about 1/2 inch by 1/2 inch at 999,999 dpi requires about 50 minutes on a 200 MHz
Pentium. The resulting .bmp file is more than 155MB and is too large to be viewed by most image
editors. This applies no matter how you use the scan, including Drag and Drop, Copy and Paste, Save
to file, Print, and TWAIN. For more information about setting resolutions, refer to the online Help or
the online User's Manual.
E. ADF (Automatic Document Feeder)
IMPORTANT: The ADF dialog appears only when you place paper in the ADF. To cancel out of the
ADF dialog box, take the paper out of the ADF.

5. When scanning to a file with the ADF and using a bitmap output type (true color, grayscale, black and
white bitmap, or web palette, each page will be placed in a separate file. When using Text or Text and
Image output type, all output will be put into one file. When using "Scan to" with an ADF for bitmap
output types (true color, grayscale, black and white bitmap, or web palette) only one page is scanned
and placed in the application chosen. This is because some applications do not handle multiple files or
launch a separate instance of the program for each file. Optimized palette and Spot Color depend on a
preview image in order to make the best image with the color palette used. Since ADF scans do not
have a preview scan, these output types are not appropriate for ADF scans and will not yield optimum
results.
When scanning with the ADF the settings for the scan will be the current settings in the software. If
you have just launched HP Precisionscan Pro the tool settings will all be at their default values. If you
have done a Load Settings then the tool settings will all be the values loaded in. If you have been
scanning from the flatbed and then scan from the ADF the settings will be the current settings from the
flatbed. If you wish to restore all the controls, tools and selection area to their default state when using
the ADF, the most foolproof method is to close HP Precisionscan Pro and re-launch the program. Then
place paper in the ADF.

G. Disabling Automatic Color Adjustment
HP Precisionscan Pro adjusts color automatically for the image type and media (such as a printer). It
makes the white background white from originals that may be slightly off-white. When the scan
changes the background to pure white, other colors in the scan may change slightly as well. Disable the
Automatic Color Adjustment in the Preferences if you want a scanned image EXACTLY like the
original.
H. Retaining settings when repeating scans
A new scan will reset scanning parameters. This allows optimum settings for each scan. Sometimes it
is convenient to keep the settings for subsequent scans without changing scanning parameters (eg. if
you are doing repetitive scans of a portion of a page in which the scan selection area does not change).
You can do this by making the appropriate settings and then performing successive final scans (scan to,
save as, or print) with each new target document. In this case, you will not see a preview image of the
new target document and the image quality will not be optimized for the new target document.
I. Drag and drop with large images
If you experience performance problems with dragging and dropping large images, try transferring the
image by saving a file and then opening the file in the target application. In some cases, these problems
can be resolved by upgrading the application to a newer version, eg. Word 2000 will handle large
images more reliably than Word 97.
J. Complex Page Output Types
When using the Text and Image output type, tool settings are automatically optimized for the image. To
save any manual adjustments made to the color or other tools in the final image, use an image output
type, such as True Color.
When using Text and Image, Text, or Black and White Scalable output types, do not use the Rotate tool
in Precisionscan Pro. The scanning software will detect text and automatically rotate the data. Using
the Rotate tool for these output types can result in unusable data in the final file.
K. OCR Display Issues
Precisionscan Pro can OCR in any supported language on any PC. However, some operating systems,
cannot display characters from all languages. For example, English Windows 95 cannnot display

6. characters from Russian, Turkish, Chinese, Korean, and some other languages. If your OCR results
display squares or other unusual symbols, choose Save As from the Scan menu in Precisionscan Pro,
save the results to an rtf file, and transfer it to a PC that supports display of the target language (for
example a Windows 2000 system with Word 2000 enabled to display the target language). See the
operating system documentation for additional details, eg. the web page
http://www.microsoft.com/office/ork/2000/six/85t2_1.htm.
L. Front Panel and Buttons
The File button on the front panel of the scanner saves a scanned image to a pdf file. If you set the
Quality setting to Large file size, you will get searchable pdf files (note: Asian languages are always
image only). Other settings for Quality will result in image only pdf files.

4. HP Utility Programs
A. HP Scanjet Copy Utility
Notes about the HP Scanjet Copy Utility:
* Use HP ColorSmart printers and drivers for best results.
* When you have a choice, print to the PCL driver rather than the PostScript driver for faster copies.
B. HP Share-to-Web
The HP Share-to-Web feature requires Internet Explorer 4.0 or higher to function. Therefore during the
HP Precisionscan Pro install, if Internet Explorer 4.0 or higher is not already installed on your
computer, HP Share to Web will not be installed. If you upgrade Internet Explorer to version 4.0 or
higher after you have installed Precisionscan Pro and want to add HP Share to Web, first run the
Precisionscan Pro install program again and select the Repair option. After that completes, run the
Precisionscan Pro install again, and select the Modify option. In the Custom Setup dialog, click on the
icon next to the HP Share-to-Web text and select "This feature will be installed on local hard drive"
from the pull-down menu. Then click next and follow the directions on the remaining dialogs.
C. Sharing a scanner (HP Precisionscan LAN)
* To install the Share Scanner feature:
1. Check that the network services are working properly (described below)
2. Install the host by installing Precisionscan Pro on a PC connected to the network.
3. Connect the scanner to this PC. Test the scanner to ensure it is installed properly.
4. Run the Share Scanner program in the HP Scanjet Utilities menu on the Start menu.

8. Right click on the scanner icon in the Windows system tray and select Automatically Start to run
Share Scanner whenever you power on your PC, otherwise you must manually start the Share
Scanner program every time this computer is restarted.
5. Install the client on another PC connected to the network by inserting the HP Scanning Software
CD. When the initial installation screen appears click on Install Software. De-select everything
that is automatically selected and select only HP Remote Scanning Installation. Follow the
instructions during the install, this may include rebooting your PC.
6. Run the Remote Scanning Setup program on the HP Scanjet Utilities menu on the Start menu.
Check Use Remote Scanner. Enter the host PC name and select a network protocol supported by
the host. The host PC name can be found by double clicking on the scanner icon in the Windows
system tray on the host PC.
* Sharing a scanner uses network services and will not work if the network services are down. If using
TCP/IP, check that the client can ping the server. Before you share the scanner over the network,
make sure file sharing and printing are enabled as follows:
Win 95 and Win 98 and Me
In the control panel, double-click the Network icon. Under the Configuration tab, click on the
File and Print Sharing button. Click both checkboxes on.
Win NT 4.0 and Win2000
Contact your network administrator to verify setup.
* If the PC sharing the scanner goes into "suspend mode" or is shut down during a remote scan, both
PCs may need to be rebooted. To prevent the PC sharing the scanner from going into suspend mode,
refer to your PC's manual for instructions on turning suspend mode option OFF.
* The host can force remote sessions to disconnect by selecting "Shut Down" from the menu displayed
when you right click the Share Scanner icon on the tray of the Windows task bar. If you do this, you
must restart Share Scanner before the scanner can be used by a remote PC.
* Using HP Precisionscan LAN, each PC can only communicate with one scanner at a time. Also,
each host can only share one scanner.
* If you are accessing a remote scanner, you can enter its IP address instead of the host PC name, if
you wish. If the host PC is configured to use DHCP to determine its IP address, this will allow the
scanner to resolve the host address correctly. To determined the host PCs IP address, run the program
IPCONFIG.exe (or WinIPCFG.exe on Win95 systems) from the DOS prompt.
* If a client is scanning on a server and the server attempts to use the scanner, a scanner not found
message will display. To determine the user using the scanner, open the Share Scanner application
(right click on the scanner icon in the Windows tray and select Open).
5. Other Application Notes
A. Using compressed tiff images
Some applications, such as Microsoft Office, Lotus Word Pro 97 and Visioneer PaperPort Deluxe 2,
have trouble importing compressed tiff images (they may appear as a solid black box or not import at
all). To avoid this, use regular tiff format.
B. Corel Applications
When you drag and drop an image into Corel PhotoPaint 7 or later, HP Precisionscan Pro will scan
twice. To avoid scanning twice, drag the scanned image to the PhotoPaint icon.
C. TWAIN and WIAApplications on Windows ME
Applications on Windows Millenium Edition scan using one of two protocols: TWAIN or WIA.
Usually the protocol can be selected from the Select Source dialog (name may vary). If you experience
problems scanning through the WIA source, try using the TWAIN source. TWAIN is the most common
and well implemented protocol. WIA is relatively new and not all applications (such as Read Iris and
Omniform) provide a complete implementation yet.
