Read the following precautions before cleaning the machine: any damages due to user’s mis-handling is not covered by the warranty: |
-
Turn the machine’s power off and unplug all the power cords.
-
Do not disassemble the machine without following the instructions in this guide.
-
Do not clean the machine with cleaning materials containing large amounts of alcohol, solvent, or other strong substances. They can discolor or distort the cabinet.
-
Do not use a vacuum cleaner to clean the toner dust, we recommend you use a cloth or tissue dampened with water to clean it. If you use a vacuum cleaner, toner blows into the air and might be harmful to you.
-
When using a dampened cloth, be careful not to drip any water into the machine: it might cause an electric shock.
-
For more safety issues, refer to the safety information chapter in the User’s Guide.
Clean the machine cabinet or the display screen 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. These accumulations can cause print quality problems, such as toner specks or smearing. Cleaning the inside of the machine clears and reduces printing quality problems.
-
Turn the machine off and unplug the power cord. Wait for the machine to cool down.
-
Open the front cover and pull the toner cartridge out.
-
With a dry, lint-free cloth, wipe away any dust and spilled toner from the toner cartridge area.
While 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 to clean. Printing quality problems can occur and cause damage to the machine.
-
Reinsert the toner cartridges. Hold the toner cartridge and align it with the corresponding slot inside the machine. Insert it back into its slot until it locks in place.
-
Close the front door. Ensure that the cover is securely closed.

The paper dust stick and the chargers of the imaging units will need to be cleaned after a specified number of paper is printed out. When the message that demands you to clean the chargers of the imaging units appears, you have to clean the paper dust stick first. Then clean the chargers. The time when the message appears depends on environmental factors like altitude, temperature, humidity, and so on. You need to clean the charger to maintain printing quality. If cleaning is done, the message will disappear automatically.
Follow the cleaning procedure below.
