88 3 Managing and maintaining the printer ENWW
Cleaning the inside of the printer
Use these steps to clean dust and residue from the inside of the printer.
To clean the inside of the printer
1 Turn the printer power off and unplug the power cord.
2 Open 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.
3 Wipe 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.)
4 Using the green handle, lift the paper-access plate and wipe off any
residue with a dry, lint-free cloth.
5 Reinstall the print cartridge, close the top cover, plug in the power
cord, and turn the printer power on.
