Cleaning the machine
If printing quality problems occur or if you use your machine in a dusty environment, you need to clean your machine
regularly to keep the best printing condition and use your machine longer.
Cleaning the cabinet of the machine with cleaning materials containing large amounts of alcohol, solvent, or
other strong substances can discolor or distort the cabinet.
If your machine or the surrounding area is contaminated with toner, use a cloth or tissue dampened with
water to clean it. If you use a vacuum cleaner, toner blows in the air and might be harmful.
Cleaning the outside
Clean the machine cabinet with a soft, lint-free cloth. Dampen the cloth slightly with water, but be careful not to let
any water drip onto or into the machine.
Cleaning the inside
During the printing process, paper, toner, and dust particles can accumulate inside the machine. This buildup can
cause print quality problems, such as toner specks or smearing. Cleaning the inside of the machine clears and
reduces these problems.
1. Turn the machine off and unplug the power cord. Wait for the machine to cool down.
2. Open the front door and pull the toner cartridge out. Set it on a clean flat surface
To prevent damage to the toner cartridge, do not expose it to light for more than a few minutes.
Cover it with a piece of paper, if necessary.
Do not touch the green surface underside of the toner cartridge. Use the handle on the cartridge to
avoid touching this area.
3. With a dry, lint-free cloth, wipe away any dust and spilt toner from the toner cartridge area.
