Cleaning the printer
General guidelines
Follow the cleaning procedure on the following page every time you
change the toner 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 toner cartridge). Skin oils
on the roller can cause print quality problems.
