Troubleshooting
Vertical lines
If black vertical streaks appear on the page:
•
The surface (drum part) of the toner cartridge inside the machine has probably been scratched. Remove the toner cartridge and
install a new one (see "Replacing the toner cartridge" on page 40).
If white vertical streaks appear on the page:
•
The surface of the LSU part inside the machine may be dirty. Clean the inside of your machine (see "Cleaning the machine" on page
42). If these steps do not correct the problem, contact a service representative.
Black background
If the amount of background shading becomes unacceptable:
•
Change to a lighter weight paper.
•
Check the environmental conditions: very dry conditions or a high level of humidity (higher than 80% RH) can increase the amount
of background shading.
•
Remove the old toner cartridge and install a new one (see "Replacing the toner cartridge" on page 40).
•
Thoroughly redistribute the toner (see "Redistributing toner" on page 39).
Toner smear
•
Clean the inside of the machine (see "Replacing the toner cartridge" on page 40).
•
Check the paper type and quality.
•
Remove the toner cartridge and install a new one (see "Replacing the toner cartridge" on page 40).
