Cleaning the printer

or whenever print-quality problems occur. As much as possible, keep the printer free from
dust and debris.

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.
