6. 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.
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. 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.
• Thoroughly redistribute the toner (see Basic Guide).
Toner smear
• Clean the inside of the machine.
• Check the paper type and quality.
• Remove the toner cartridge and install a new one.
