REGULAR MAINTENANCE

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

Warning

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.

Caution

Do not use thinner, benzene, or similar volatile cleaning agents to clean the machine. These may degrade or discolour the housing.
Use a soft cloth to gently wipe off dirt from the area on the operation panel with a mirror-like finish. If you use a stiff cloth or rub hard, the surface may be damaged.

CLEANING THE DOCUMENT GLASS AND AUTOMATIC DOCUMENT FEEDER

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.

Clean the document scanning area on the document glass with the glass cleaner.

Replace the glass cleaner.

If paper misfeeds frequently occur when feeding envelopes or heavy paper through the bypass tray, wipe the surface of the feed roller with a clean soft cloth moistened with water or a neutral detergent.
