6. Troubleshooting

Vertical lines If black vertical streaks appear on the page:

• The surface (drum part) of the imaging unit 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 imaging unit and install a new one.

Toner smear • Clean the inside of the machine.

• Check the paper type and quality.

• Remove the imaging unit and install a new one.
