Fixing print quality issues
The symptoms described in this chapter might 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 might need to install a toner cartridge.
Initial print quality check
Before troubleshooting specific print problems, complete the following initial print quality check:
•
Use only genuine Lexmark supplies. Third-party supplies may cause print quality problems.
•
The printer must be in a location that follows the recommended operating environment specifications.
See
“Operating environment” on page 361
•
Check the life status of all supplies. Any supply that is low should be replaced.
•
Load 20
‑
lb plain letter or A4 paper. Make sure the paper guides are properly set and locked. From the
control panel, set the paper size and type to match the paper loaded in the tray.
•
Print a menu settings page. Be sure to keep the original menu settings page to restore the customer’s
custom settings if needed.
•
Verify on the menu settings page if the following are set to their default values:
–
Print resolution: 600 dpi
–
Toner darkness: 8
•
Check the transfer roll for damage. Replace if damaged.
•
Check the toner cartridge and imaging unit for damage. Replace if damaged.
•
Print the print quality pages to see if the problem remains. Use Tray 1 to test print quality problems.
•
Print a print quality test page, and then look for variations in the print from what is expected. Verify if the
settings under EP Setup are set to their default values. See
