Cleaning the machine
If printing quality problems occur or if you use your machine in a dusty enviroment, you need to clean your machine regularly to keep it in the best printing condition
and use your machine longer.
• Cleaning the cabinet of the machine with cleaning materials containing large amounts of alcohol, solvents, or other strong substances can discolor or distort the
cabinet.
• If your machine or the surrounding area is contaminated with toner, we recommend you 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 to you.
9
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.
10
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.
Use a dry lint free cloth when cleaning the inside of the machine, be careful not to damage the transfer roller or any other inside parts. Do not use solvents such as
benzene or thinner. Printing quality problems can occur and cause damage to the machine.
