Print quality service check

Note: This symptom may require replacement of one or more CRUs (Customer Replaceable Units) designated
as supplies or maintenance items, which are the responsibility of the customer. With the customer's permission,
you may need to install an ITU, fuser assembly, second transfer roll, or print cartridge.

Check the following before proceeding with any of the print quality service checks.

• Use tray 1 (internal tray) to test the print quality of the base printer.
• Be sure the fuser assembly is installed correctly.
• Be sure the ITU assembly is installed correctly.
• Be sure the second transfer roll is installed correctly.
• Check the media in tray 1 to make sure it meets paper specifications.
• Run a copy of the CE Test page. This sets all the printer defaults to the correct settings to check for print
quality.
• If a specific color has a print quality problem, first try a new cartridge to help isolate the problem.

An incorrect printer driver for the installed software can cause print quality problems. Incorrect characters could
print, and the copy may not fit the page correctly.

Note: Some 201.xx Paper Jam errors can be caused by a faulty print cartridge.

Blank page (no image)

• If there is no image (blank page) and no error codes displayed, go to step 1.

• If there is no image (blank page) but error codes are displayed, go to “Service error code and paper jam
message table” on page 2-7 and perform the necessary action.

Residual image

• If only one color has a residual image repeated every 95 mm, replace the print cartridge.
• If all colors have a residual image 147 mm from the top of the page, replace the fuser assembly.
Note: Do the following steps before you replace the fuser assembly:

1. Check Media Type setting on the operator panel. If the setting is for light paper, select the correct
setting for the current media type.
2. If the problem continues, set the fuser temperature selection to High.
3. If the problem continues, check the page count. If the page count is greater than 200K copies and the
fuser has not been replaced, advise the customer to install a new fuser CRU or a maintenance kit.
• If only one color has a residual image problem, go to “Horizontal lines or streaks” on

• If all colors have a residual image problem, go to “Residual image” on page 2-101.

Uneven printing

• If all colors have uneven print, replace the ITU assembly.

• The uneven print may appear as spots or streaks that are different on each page. The most likely cause for
