49
Garbled Characters on Printed Output
Cause: Incorrect or corrupt print driver
Resolution:
Download and reinstall the appropriate print driver for your specific print device and operating system.
50
Garbled Characters on Printed Output
Cause: Loose or damaged data cable
Resolution:
Verify the data cable is securely connected. Try a different data cable.
51
Garbled Characters on Printed Output
Cause: Attempting to print a corrupt file
Resolution:
Try printing smaller sections of document. For example, print individual pages to see if you can locate a specific problem in the file.
52
Garbled Characters on Printed Output
Cause: Virus or malware
Resolution:
Run virus and malware scanners.
53
Garbled Characters on Printed Output
Cause: Software issue
Resolution:
Try printing from another software program or running a printer test page. If you've determined the problem is limited to one particular software, check the manufacturer's Website for a fix.
54
Garbled Characters on Printed Output
Cause: Operating system issue
Resolution:
Look for a hotfix or patch from your operating system manufacturer.
55
Vertical Lines on the Page
Cause: Toner on the main corona or transfer corona wire
Resolution:
Can cause vertical white areas on a laser printout. Clean the corona wires or replace the toner cartridge, which has new corona wires in it.
56
Vertical Lines on the Page
Cause: Low resolution image
Resolution:
Lower resolution images that display okay on screen might be stretched out when printed. This increases the likelihood of the small spaces between image pixels being visible, which can lead to vertical lines running down the paper. Obtain a higher resolution image.
57
Vertical Lines on the Page
Cause: Print resolution setting is too low
Resolution:
When printing at a very low dpi, the printer can't increase the dot size pitch (how large an individual dot is) to compensate for a low number of resolution lines in the print. Increase the print resolution setting.
58
Vertical Lines on the Page
Cause: Dust and debris on the printer heads and rollers block the ink from getting to the page
Resolution:
Clean the print heads and rollers.
59
Vertical Lines on the Page
Cause: Low ink/toner
Resolution:
Gently shake the cartridge to see if you can get more ink/toner out of it. Replace the cartridge.
60
Back up in the Print Queue
Cause: Print job can't be interpreted by the printer or print server
Resolution:
Causes it to lock. Delete the print job from the print queue. If you can't delete the job from the queue, stop and restart the print spooler service.
61
Back up in the Print Queue
Cause: Bi-directional printing is enabled but not supported by the printer
Resolution:
Turn off bi-directional printing.
62
Back up in the Print Queue
Cause: Corrupt or incorrect print driver
Resolution:
Reinstall correct print driver.
63
Low Memory Errors
Cause: The memory setting on the printer driver is too low
Resolution:
By default the memory setting for some printer drivers is configured to the lowest possible setting. Use the printer's Device Options or Settings to increase the printer memory.
64
Low Memory Errors
Cause: Printer memory is being used for another complex print job
Resolution:
Wait for the first job to complete or interrupt it if your new print job takes priority.
65
Low Memory Errors
Cause: Not enough memory in the printer
Resolution:
If possible, upgrade the printer's memory. If you have an older printer where you can't upgrade the memory, you might want to consider purchasing a new printer.
66
Printer Access Denied
Cause: Credentials were not saved properly when the printer was installed
Resolution:
Remove and then reinstall the printer, making sure to save credentials when prompted.
67
Printer Access Denied
Cause: The user doesn't have access
Resolution:
Add the user to the printer's access list. Verify the user is not a member of a group that is denied access to the printer.
68
Printer Access Denied
Cause: Print server or host computer does not have correct print drivers for client
Resolution:
Using Printer Management, install the correct drivers.
69

Printer Won't Work
Cause: Incorrect or corrupt print driver
Resolution:
Download and reinstall the appropriate print driver for your specific print device and operating system.
77
Printer Won't Work

Refer to your printer manufacturer's documentation to adjust the print driver's color settings. For example, Epson printers use Color Control and sRGB print modes, Canon printers have Color Adjustment modes, and HP printers have a Color tab with available settings.
84
Unable to Install Local Printer
Cause: Printer is not turned on
Resolution:
Power on the printer.
85
Unable to Install Local Printer
Cause: Driver conflict
Resolution:
Remove previous versions of the printer driver. You might have to do this manually from within the file system and, if in Windows, the Registry.
86
Unable to Install Local Printer
Cause: Print Spooler service isn't running
Resolution:
Start the print spooler service. Make sure it is set to automatic startup.
87
Unable to Install Local Printer
Cause: A service the Print Spooler depends on isn't running
Resolution:
View the Print Spooler's dependencies and verify each is running. Start any that aren't running. Make sure the services are set to automatic startup.
88
Unable to Install a Network Printer
Cause: The print server or host computer has different OS or different OS version and it doesn't have the driver for your operating system available
Resolution:
Check to see if your printer manufacturer provides a proprietary install kit. This kit will install the driver on your computer without verifying the physical presence of the printer.
89

92
Printing Blank Pages - Non Laser Printers
Cause: Separator pages is enabled
Resolution:
Turn off the separator page feature in the printer's preferences.
93
Printing Blank Pages - Non Laser Printers
Cause: Incorrect paper size is selected
Resolution:
Select the correct paper size in the printer's preferences.
94
Printing Blank Pages - Non Laser Printers
Cause: Clogged inkjet print heads
Resolution:
Use the printer's software to clean the print heads.
95
Printing Blank Pages - Non Laser Printers
Cause: A cartridge is empty
Resolution:
Replace any empty cartridges. Many color printers won't allow you to print in B&W if a single color cartridge is empty. Usually the printer won't print, but sometimes it will feed the paper through without printing anything on it.
96
Printing Blank Pages - Laser Printers
Cause: No toner is available for print
Resolution:
If you just installed a toner cartridge, make sure you removed the sealing tape. Replace the toner cartridge if empty.
97
Printing Blank Pages - Laser Printers
Cause: Debris is obstructing the laser beam
Resolution:
Clean the inside of the printer and remove any debris from within the paper path.
98
Printing Blank Pages - Laser Printers
Cause: No transfer roller voltage
Resolution:
Perform a half-way test. Determine if there is an image on the imaging drum. If there is an image on the drum, verify sure the transfer roller is installed and working. Without transfer roller voltage, the toner isn't pulled to the paper from the surface of the drum. Replace the transfer roller if necessary.
99
Printing Blank Pages - Laser Printers
Cause: No developing bias
Resolution:
Perform a half-way test. Determine if there is an image on the imaging drum. If there isn't an image on the drum, clean the high-voltage power supply contacts. If this doesn't help, you might need to replace the high-voltage unit or the engine controller board.
100
Printing Blank Pages - Laser Printers
Cause: Defective laser scanner cable
Resolution:
Perform a half-way test. Determine if there is an image on the imaging drum. If there isn't an image on the drum, low-level signals exchanged between the laser/scanner assembly and the engine controller board could theoretically affect laser output. You might need to replace the laser/scanner cable assembly.
101
No Image on the Printer Display
Cause: Printer power is off
Resolution:
Turn on the power to the printer.
102
No Image on the Printer Display
Cause: Printer needs to be reset
Resolution:
Cycle the power off, remove the power cord, wait 10 seconds, plug the power cord back in, and then power the printer on again.
103
No Image on the Printer Display
Cause: Surge protector is preventing power from reaching printer
Resolution:
Plug printer directly into a wall outlet.
104
No Image on the Printer Display
Cause: Printer's firmware needs updating
Resolution:
Download and install firmware update from your printer manufacturer's Web site.
105
No Image on the Printer Display
Cause: Display panel needs to be replaced
Resolution:
Hardware replacement of the display panel.
