Remove and reinstall the printer.

Use a system restore to roll your system back to a time when you could connect.

45
Q

Unable to Connect to the Printer

Cause: Damaged or outdated print driver

A

Resolution:

Download and reinstall the print driver.

46
Q

49
Q

Garbled Characters on Printed Output

Cause: Incorrect or corrupt print driver

A

Resolution:

Download and reinstall the appropriate print driver for your specific print device and operating system.

50
Q

Garbled Characters on Printed Output

Cause: Loose or damaged data cable

A

Resolution:

Verify the data cable is securely connected. Try a different data cable.

51
Q

Garbled Characters on Printed Output

Cause: Attempting to print a corrupt file

A

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
Q

Garbled Characters on Printed Output

Cause: Virus or malware

A

Resolution:

Run virus and malware scanners.

53
Q

54
Q

Garbled Characters on Printed Output

Cause: Operating system issue

A

Resolution:

Look for a hotfix or patch from your operating system manufacturer.

55
Q

Vertical Lines on the Page

Cause: Toner on the main corona or transfer corona wire

A

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
Q

Vertical Lines on the Page

Cause: Low resolution image

A

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
Q

Vertical Lines on the Page

Cause: Print resolution setting is too low

A

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
Q

Vertical Lines on the Page

Cause: Dust and debris on the printer heads and rollers block the ink from getting to the page

A

Resolution:

Clean the print heads and rollers.

59
Q

Vertical Lines on the Page

Cause: Low ink/toner

A

Resolution:

Gently shake the cartridge to see if you can get more ink/toner out of it. Replace the cartridge.

60
Q

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
Q

Back up in the Print Queue

Cause: Bi-directional printing is enabled but not supported by the printer

A

Resolution:

Turn off bi-directional printing.

62
Q

Back up in the Print Queue

Cause: Corrupt or incorrect print driver

A

Resolution:

Reinstall correct print driver.

63
Q

Low Memory Errors

Cause: The memory setting on the printer driver is too low

A

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
Q

Low Memory Errors

Cause: Printer memory is being used for another complex print job

A

Resolution:

Wait for the first job to complete or interrupt it if your new print job takes priority.

65
Q

Low Memory Errors

Cause: Not enough memory in the printer

A

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.

92
Q

Printing Blank Pages - Non Laser Printers

Cause: Separator pages is enabled

A

Resolution:

Turn off the separator page feature in the printer’s preferences.

93
Q

Printing Blank Pages - Non Laser Printers

Cause: Incorrect paper size is selected

A

Resolution:

94
Q

Printing Blank Pages - Non Laser Printers

Cause: Clogged inkjet print heads

A

Resolution:

Use the printer’s software to clean the print heads.

95
Q

Printing Blank Pages - Non Laser Printers

Cause: A cartridge is empty

A

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
Q

Printing Blank Pages - Laser Printers

Cause: No toner is available for print

A

Resolution:

If you just installed a toner cartridge, make sure you removed the sealing tape. Replace the toner cartridge if empty.

97
Q

Printing Blank Pages - Laser Printers

Cause: Debris is obstructing the laser beam

A

Resolution:

98
Q

Printing Blank Pages - Laser Printers

Cause: No transfer roller voltage

A

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
Q

Printing Blank Pages - Laser Printers

Cause: No developing bias

A

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
Q

Printing Blank Pages - Laser Printers

Cause: Defective laser scanner cable

A

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
Q

No Image on the Printer Display

Cause: Printer power is off

A

Resolution:

Turn on the power to the printer.

102
Q

No Image on the Printer Display
