Condition Possible cause Suggested solutions
Condition Suggested solutions
Light or faded print
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 Toner”
on page 8.7. 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
Specifications” on page F.6.
• If the entire page is light, the print resolution setting is too
low or the toner save mode is on. Adjust the print
resolution and turn the toner save mode off. See page 4.8
and page 2.23, respectively.
• A combination of faded or smeared defects may indicate
that the toner cartridge needs cleaning. See “Cleaning the
Drum” on page 8.11.
• The surface of the LSU part inside the machine may be
dirty. Clean the LSU (see page 8.5).
