Vertical lines
If black vertical streaks appear on the page:
• The imaging unit inside the printer has probably been
scratched. Install a new imaging unit.
If white vertical lines appear on the page:
• The surface of the LSU may be dirty. Clean the LSU. See
page 6.29.
Color or Black
background
If the amount of background shading becomes unacceptable,
the procedures below may fix the problem.
• Change to lighter weight pages. See “Paper Specifications” on
page E.4.
• Check the printer’s environment; very dry (low humidity) or
high humidity (higher than 80% RH) conditions can increase
the amount of background shading.
• Remove the old imaging unit and install a new one. See
“Replacing the Imaging Unit” on page 6.14.
Toner smear
• Clean the inside of the printer. See “Cleaning the Inside of the
Printer” on page 6.30
• Check the paper type and quality. See “Paper Specifications”
on page E.4.
• Remove the transfer belt and install a new one. See “Replacing
the Transfer Belt” on page 6.22.
Vertical repetitive
defects
If marks repeatedly appear on the printed side of the page at
even intervals:
• Clean the inside of the printer. See “Cleaning the Inside of the
Printer” on page 6.30. After cleaning the inside of the printer,
if you still have the same problems, install a new toner
cartridge of the problem color. See “Replacing Toner
Cartridges” on page 6.8.
• Parts of the printer may have toner on them. If the defects
occur on the back of the page, the problem will likely correct
itself after a few more pages.
• The fusing assembly may be damaged. Contact a service
representative.
