Cleaning the Printer

Before beginning these steps, turn the printer off and unplug the power cord.

1Open the top cover and remove the toner cartridge.

WARNING!

Avoid reaching too far into the printer.

The adjacent fusing area might be hot!

Caution

To prevent damage to the toner cartridge, do not expose it to light for more than a few minutes.

2Wipe any dust or dirt off the paper feed guides (shaded areas) with a dry, lint-free cloth.

Note

If toner gets on your clothing, wipe it off with a dry cloth and wash clothing in cold water. (Hot water sets toner into fabric.)

3Using the green handle, lift the paper access plate and wipe off any residue with a dry, lint-free cloth.
