Cleaning the printer
Use the cleaning procedure on the following page every time you change the print cartridge or
whenever print-quality problems occur. As much as possible, keep the printer free from dust and
debris.
Clean the outside of the printer with a slightly water-dampened cloth.
Clean the inside with a dry, lint-free cloth.
CAUTION Do not use ammonia-based cleaners on or around the printer.
While cleaning the printer, be careful not to touch the transfer roller (the black, rubber roller located
underneath the print cartridge). Skin oils on the roller can cause print-quality problems.
