Cleaning the product
WARNING! Before you perform these steps, unplug the printer to avoid shock hazard.
To maintain quality, thoroughly clean the printer at the following times:
■ Any time a new print cartridge is installed
■ After printing approximately 2,000 pages
■ Whenever print-quality problems appear
Clean the outside of the printer with a water-dampened cloth. Clean the inside with only a dry, lint-free
cloth (such as a lens tissue).
WARNING! Avoid touching the heating element in the fuser. It might be very hot and can cause
burns.
CAUTION To avoid permanent damage to the printer, do not use ammonia-based or ethyl
alcohol-based cleaners on or around the printer.
CAUTION Do not touch the surface of the black-sponge transfer roller. Contaminants on the
roller can cause print-quality problems.
