Fixing print quality issues
• “Initial print quality check” on page 48
• “Print quality checks” on page 49
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:
1 The printer must be in a location that follows the recommended operating environment specifications. See
“Operating environment” on page 239.
2 Check the life status of all supplies. Any supply that is low should be replaced.
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.
