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.

Before troubleshooting specific print problems, complete the following initial print quality check:
1 The printer must be in a location that follows the recommended operating environment specifications. See
“Operating environment” on page 281.

3 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.
4 Print a Menu settings page. Be sure to keep the original Menu settings page to restore the customer's custom
settings if needed.
5 Verify on the Menu settings page if the following are set to their default values:
• Print resolution: 600 dpi
