2Open the front cover. Pull the toner cartridge and remove it from the printer.

3With a dry, lint-free cloth, wipe away any dust and spilled toner from the toner cartridge area and the toner cartridge cavity.

NOTE: 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.

4Locate 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.
