Use these steps to clean dust and residue from the inside of the printer.

To clean the inside of the printer

1Turn the printer power off and unplug the power cord.

2Open the top cover and remove the print cartridge.

WARNING!

Avoid reaching too far into the printer. The adjacent fusing area might be hot.

CAUTION

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

3Wipe 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.)

4Using the green handle, lift the paper-access plate and wipe off any residue with a dry, lint-free cloth.

5Reinstall the print cartridge, close the top cover, plug in the power cord, and turn the printer power on.
