7.11 Troubleshooting
Print Quality Problems
Problem Possible Cause and Remedy
If a vertical white streak or faded area appears on the page:
• The toner supply is low. You may be able to temporarily
extend the toner cartridge life. See “Redistributing the
Toner” on
page 6.7 . If this does not improve the print
quality, install a new toner cartridge.
• The paper may not meet paper specifications (for
example, the paper is too moist or too rough). See “Paper
Type and Size” for faxing on
page 1.17 and “Selecting
Print Media” for PC printing on page 4.1 .
• If the whole page is light, Toner Save Mode may be on.
Turn the Toner Save Mode option off on front panel or
within the printer properties as your setting. See
page 1.22 and 4.16 respectively.
• A combination of faded and smeared defects may indicate
that the toner cartridge needs cleaning. See “Cleaning the
OPC Drum” on
page 6.2 .
• The surface of scanner parts inside the machine may be
dirty. See “Cleaning the Document Scanner” on page 6.5 .

If black vertical streaks appear on the page:

probably been scratched. Install a new toner cartridge.
