7.2 Cleaning the Main Unit
When cleaning this product, use the designated cleaning materials exclusive to it. Other
cleaning materials may result in poor performance of the product. Never use aerosol
cleaners to avoid catching fire and explosion.
When cleaning this product, always switch off and unplug it. Access to a live machine
interior may cause electric shock.
Cleaning the Exterior
Using volatile solvents such as benzine or thinner, or spraying with insecticide may cause discoloration,
deformation, or cracks on the covers or exterior.
Be cautious with water, since too much moisture could cause the machine to malfunction.
1. Wipe the exterior of the machine with a soft, moistened, and tightly-squeezed cloth.
Do not use cleaning agents other than water or neutral detergent.
For stubborn stains, apply a small amount of mild detergent to the cloth and gently wipe the stain off.
2. Wipe the moisture off with a dry soft cloth.
Cleaning the Interior (LED Printheads)
Normally, clean the LED printheads when you replace a drum cartridge and the waste toner
container. However, if you have image quality problems such as white or colored stripes appearing
on outputs, clean the LED printheads.
1. Make sure that the machine is not operating, and open the right door.
