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 it in the best printing condition and use your machine longer. CAUTION: ● 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. 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. CAUTION: ● 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 area of the toner cartridge. Use the handle on the cartridge to avoid touching this area. ● 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. NOTE: ● Use a dry lint-free cloth to clean the machine. ● Turn the machine off and unplug the power cord. Wait for the machine to cool down. ● Illustrations on this user's guide may differ from your machine depending on its options or models. Check your machine type. ENWW Cleaning the machine 89

●
If your machine or the surrounding area is contaminated with toner, we recommend you use a cloth or

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.

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.

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 area of the toner cartridge. Use the handle on the cartridge to avoid touching this
