  3. 3. Objectives <ul><li>Upon completion of this course, the participant will be able to: </li></ul><ul><li>Identify at least three results of print media that can contribute to poor print quality </li></ul><ul><li>Describe basic troubleshooting steps for determining printer issues </li></ul><ul><li>Identify key causes for paper issues </li></ul>
  4. 4. Overview <ul><li>This presentation will provide a basic overview of troubleshooting for LaserJet printers </li></ul><ul><li>The processes for troubleshooting can vary by model and manufacturer </li></ul><ul><li>Model specific troubleshooting can be based off of the printer control panel error messages </li></ul><ul><li>Focus will be on the following: </li></ul><ul><ul><li>Print Quality Troubleshooting </li></ul></ul><ul><ul><li>Basic Troubleshooting </li></ul></ul><ul><ul><li>Paper Issues </li></ul></ul>
  5. 5. Print Quality Troubleshooting <ul><li>The media being used is usually the cause of poor print quality and related issues </li></ul><ul><li>Problems with print quality usually result from print media that does not meet the specifications of the printer, has been stored improperly, or is not in good condition </li></ul><ul><li>Most LaserJet printers are designed to accept different types of print media </li></ul><ul><li>Media that is designed to work specifically for the printer should be used if possible </li></ul>
  6. 6. Print Quality Troubleshooting <ul><li>To determine if the print media is causing quality related problems, the following should be addressed: </li></ul><ul><li>The media should meet or exceed the specifications set by the manufacturer </li></ul><ul><li>Media must be in good condition with no physical damage, wrinkles or bends </li></ul><ul><li>Environmental and storage practices can also cause media related problems, such as temperature, humidity, exposure to sunlight and cleanliness </li></ul><ul><li>Is the user following the correct procedures for printing? </li></ul>
  7. 7. Basic Troubleshooting <ul><li>If the cause of the printing issue cannot be determined, the following is basic troubleshooting that can be performed: </li></ul><ul><li>Try print media from a different batch, or from a different manufacturer </li></ul><ul><li>Flip the paper over in the input tray, or turn it from front to rear, or both </li></ul><ul><li>If issue pertains to printing an envelope, print a sheet of paper to determine if the problem is being caused by the envelope </li></ul><ul><ul><li>If the paper prints fine, check the envelope again </li></ul></ul><ul><ul><li>If the paper’s print quality is poor, there may be a printer problem </li></ul></ul>
  8. 8. Paper Issues <ul><li>If jammed paper is reused, it can damage the printer! </li></ul><ul><li>If paper is jamming frequently, consider the following: </li></ul><ul><ul><li>The paper may be too stiff or too heavy, and may not be able to make its way through the paper path </li></ul></ul><ul><ul><li>If the paper is not cut to specification, it can cause poor print alignment, improper fit in the tray, or problems for the paper sensors </li></ul></ul>
  9. 9. Paper Issues <ul><li>If the printer is frequently feeding multiple sheets of paper: </li></ul><ul><ul><li>Paper should not be added in small amounts into the input tray, this can cause alignment problems </li></ul></ul><ul><ul><li>If the paper is too dry, or not moist enough the paper may become less conductive and create static buildup </li></ul></ul><ul><ul><li>Paper may be embossed or have raised letterhead </li></ul></ul><ul><ul><li>Paper adjustments are set incorrectly </li></ul></ul>
  10. 10. Troubleshooting Strategies <ul><li>The following are some troubleshooting tips that should be helpful when trying to resolve issues over the phone </li></ul>Press the off-line button or pause button on the printer to return the printer to on-line status If the printer is off-line, no print jobs will be accepted Print job is not reaching the printer Reseat plug to ensure proper power Reseat Ribbon cable and check for damage Indicates the printer is not getting power. Damaged cables or improper cable types can prevent a print job from being transferred to the printer No power light on printer or printer is not being seen by the operating system Change the printer choice in the application If another printer is the default or was used the last time, jobs are being sent to the wrong printer Print job is being sent to the wrong printer Possible Solutions Information Provided Troubleshooting Issue
  11. 11. Troubleshooting Strategies Check that off-line printing is not selected in the properties Check that the job is not paused Purge the first print job Reboot computer and/or printer The Print Manager in the OS created the jobs but the spooler has not sent them to the printer. If no jobs in the Manager, continue troubleshooting steps Print jobs to not reach the printer Clean print heads or drum Replace ink cartridges or toner Change print quality settings in the printer properties Light blinking, uneven printing, colors missing or faded, or streaks on the paper can indicate problems with ink or toner supply, laser drum damage, or wrong settings Print quality is poor Clear the paper path Add acceptable paper type Change ink cartridges, remembering to remove any packaging tape Possible indication of a paper jam, no paper, or no ink. Wrong paper type, not enough paper in the tray, or the printer not sitting flat can cause a paper jam Message lights blinking on printer or display screen shows error message Possible Solutions Information Provided Troubleshooting Issue
  12. 12. Troubleshooting Strategies Delete files in the Temp directory - *tmp Delete files in the spool/printers directory - *spl Ensure there is enough space Scan and defrag the partition Windows uses the hard disk partition that contains the windir to temporarily store print jobs before sending them to the printer. Insufficient space for the content may cause the errors Incomplete documents, garbled characters or documents print slowly Choose to print directly to the printer in the printer properties. Disable bi-directional support Verify the printer manufacturer and model number. Dispatch tech to reinstall drivers If a test page can be printed from a command prompt and not Windows, the Windows print driver is corrupted. No printing can occur from the DOS prompt to a USB printer. Printing from command prompt but not from Windows Reboot computer to clear memory and restart the application Dispatch repair tech to reinstall the application If a test page can be printed then the OS print driver is working. If no test page can be printed, continue troubleshooting steps Cannot print from an application Possible Solutions Information Provided Troubleshooting Issue
  13. 13. Troubleshooting Strategies At a command prompt type: Net uselpt1 erver nameshare name /p Capture the printer port Cannot print from a DOS based program to a network printer Check the mapped path in the printer properties If possible, check that the print server is on and running Ping the print server The print server must be on, the path to the printer must be correct, and both computers must have network connectivity Cannot send print jobs to networked printer or TCP/IP printer Make sure the printer port is correct. Locally, this is usually LPT1 Networked printers are mapped to a specific location Check for conflicts in the Device Manager If the printer port is inactive or mapped to another location, print jobs will not print to the local printer. USB ports are not supported in Windows 95 OEM version or Windows NT Incorrect printer port or port conflicts Possible Solutions Information Provided Troubleshooting Issue
  14. 14. Troubleshooting Strategies In the Details tab of the printer properties, enter the number of seconds for the timeout session in the Timeout Settings group Transmission retry is the amount of time in seconds the printer waits before it cannot accept characters Print job times out Go to the printer properties and click the Details tab Select to capture the printer port and then type in a path if it needs to be entered, otherwise the LPT port is chosen Capture the printer port Cannot print from Windows to a network printer but network connectivity is not a problem Possible Solutions Information Provided Troubleshooting Issue
