Service tip
Before troubleshooting any print quality problems, do the following:
1. Print a menu settings page, and check the life status of all supplies. Any supplies that are low should be
replaced.
To print a Menu Settings page from the home screen, navigate to:
> Reports > Menu Settings Page
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 the following is set to the default level:
• Color Correction: Set to Auto.
• Print Resolution: Set to 1200 dpi (print quality problems should be checked at different resolution
settings).
• Toner Darkness: Set to 4 (default).
• Color Saver: Set to OFF.
• RGB Brightness, RGB Contrast, RGB Saturation: Set to 0.
• Color Balance: Select Reset Defaults to zero out all colors.
• Check the paper type, texture and weight settings against what is loaded in the printer.
Once the printer has been restored to its default levels, do the following:
1. Inspect the imaging unit for damage, including the developers and toner cartridges. Replace if damaged.
2. If paper other than 20lb plain letter/A4 paper is being used, load 20lb plain letter/A4.
3. Print the Print Quality pages to see if the problem remains. Look for variations in the print from what is
expected.
To print the quality pages:
a. Enter the Diagnostics Menu (Turn off the printer, press and hold 3 and 6, turn
on the printer, and release the buttons when the progress bar appears.)
b. Navigate to PRINT TESTS > Print Quality Pages.
c. Printing Quality Test Pages appears and the pages print.
