Print quality issues
Note: These symptoms may require replacement of one or more CRUs (Customer Replaceable Units)
designated as supplies or maintenance items, which are the responsibility of the customer.
Service tip: Before troubleshooting any print quality problems, do the following:
1.
Print a menu settings page, and then check the life status of all supplies. Any supplies that are low should
be replaced.
Note: Be sure and keep the original menu page to restore the customer's custom settings if needed.
2.
On the menu page, make sure that everything is set to the default level.
3.
Check the ink cartridges, and install new cartridges if necessary.
4.
If paper other than 20 lb plain letter/A4 paper is being used; load 20 lb plain letter/A4, and print the Print
Test Page to see if the problem remains.
5.
Use Tray 1 to test print quality problems.
6.
Print the Print Test Page , and then look for variations in the print from what is expected.
An incorrect printer driver for the installed software can cause problems. Incorrect characters could print, and
the copy may not fit the page correctly.
