BEFORE USING THE MACHINE►MAINTENANCE

This section explains how to clean the machine, replace the toner cartridge, the waste toner box, and the stamp 
cartridge.

To ensure that the machine continues to provide top quality performance, periodically clean the machine.

If the document glass or document backplate sheet becomes dirty, the dirt will appear as dirty spots, colored lines, or 
white lines in the scanned image. Keep these parts clean at all times.
Wipe the parts with a clean, soft cloth.
If necessary, moisten the cloth with water or a small amount of neutral detergent. After that, wipe with a clean dry cloth.
Examples of lines in the image

Do not use a flammable spray to clean the machine. If gas from the spray comes in contact with hot electrical components or 
the fusing unit inside the machine, fire or electrical shock may result.

• Do not use thinner, benzene, or similar volatile cleaning agents to clean the machine. These may degrade or discolor the 

housing.

• Use a soft cloth to gently wipe off dirt from the area on the operation panel with 

a mirror-like finish (shown at right). If you use a stiff cloth or rub hard, the 
surface may be damaged.
