Print Quality Service Checks
Note: This symptom may require replacement of one or more CRU's (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
ITM, Fuser Assembly or 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 will set 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 Paper Jam errors can be caused by a faulty print cartridge.
