White Spots

White spots appears on the page:

• The paper is too rough and a lot of dirt from a paper falls to the inner devices within the

machine, so the transfer roller may be dirty. Clean the inside of your machine. Contact a
service representative.

• The paper path may need cleaning. Contact a service representative.

Vertical lines

• If black vertical streaks appear on the page, the drum inside the toner cartridge has probably

been scratched. Install a new toner cartridge. See "Replacing the Toner Cartridge".

• If white vertical streaks appear on the page, the surface of the LSU part inside the printer

may be dirty. Clean the LSU (see "Cleaning the Interior").

Gray background

If the amount of background shading becomes unacceptable:

• Change to lighter weight pages. See "Paper Specifications".

• 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 toner cartridge and install a new one. See "Replacing the Toner Cartridge".

Toner smear

• Clean the inside of the printer. See "Cleaning the Interior".

• Check the paper type and quality. See "Paper Specifications".

• Remove the toner cartridge and install a new one. See "Replacing the Toner Cartridge".
