Open the front cover. Pull the toner cartridge and remove it
from the printer.
3 With a dry, lint-free cloth, wipe away any dust and spilled
toner from the toner cartridge area and the toner cartridge
cavity.
N OTE : To prevent damage to the toner cartridge, do not expose it
to light for more than a few minutes. Cover it with a piece of paper,
if necessary and keep it in a flat and clean place. Also, do not touch
the black transfer roller inside the printer.

Locate the long strip of glass (LSU) inside the top of the
cartridge compartment, and gently swab the glass to see if
dirt turns the white cotton black.
