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