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.
