5. Troubleshooting
Vertical lines
If black vertical streaks appear on the page:
•
The surface (drum part) of the cartridge inside the machine has probably been scratched. Remove the cartridge and install a new
one (see "Replacing the toner cartridge" on page 62).
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
70). If these steps do not correct the problem, contact a service representative.
Black or color 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 62).
•
Thoroughly redistribute the toner (see "Redistributing toner" on page 61).
Toner smear
•
Clean the inside of the machine (see "Cleaning the machine" on page 70).
•
Check the paper type and quality.
•
Remove the toner cartridge and install a new one (see "Replacing the toner cartridge" on page 62).
