Print quality issues

Note:

This symptom may 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 may need to install a developer (toner) cartridge or photoconductor unit.

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.

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: Touch Reset Defaults to zero out all colors.
–Check the paper type, texture and weight settings against what is loaded in the printer.

3.

Inspect the transfer module (transfer belt, and transfer roll) for damage. Replace if damaged.

4.

Inspect the imaging units and toner cartridges for damage. Replace if damaged.

5.

If paper other than 20lb plain letter/A4 paper is being used, load 20lb plain letter/A4 and print the Print
Quality pages to see if the problem remains.

6.

Use Tray 1 to test print quality problems.

7.

Print the Print Quality Pages, 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.
