CLEANING A 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 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, we recommend you use 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.
1. Turn the machine off and unplug the power cord. Wait for the machine to
cool down.
2. Open the front cover 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 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.
4. Locate the long strip of glass (LSU) inside the top of the cartridge
compartment and gently clean the glass with a swab.
5. Reinsert the toner cartridge and close the front cover.
6. Plug in the power cord and turn the machine on.
Cleaning the scan unit
Keeping the scan unit clean helps ensure the best possible copies. We
suggest that you clean the scan unit at the start of each day and during the
day, as needed.
1. Slightly dampen a soft, lint-free cloth or paper towel with water.
2. Open the scanner lid.
3. Wipe the surface of the scanner glass and the document feeder glass
until it is clean and dry.
