124   9 Cleaning and maintenance

EN

Use a soft, damp, lint-free cloth to wipe dust, smudges, and stains off the exterior of the product.

Dirty glass, from fingerprints, smudges, hair, and so on, slows down performance and affects the 
accuracy of special features such as fit to page and copy.

Turn off the product, unplug the power cord from the electrical socket, and raise the lid.

If you have a 220V product, turn off the power switch.

Clean the glass with a soft cloth or sponge slightly moistened with nonabrasive glass cleaner.

Do not use abrasives, acetone, benzene, ethyl alcohol, or carbon tetrachloride on the glass; these 
can damage it. Do not place liquids directly on the glass. They may seep under it and damage the 
product.

Dry the glass with a chamois or cellulose sponge to prevent spotting.

Dust might appear on the underside of the glass, but this cannot be cleaned and it has no effect on 
the copy or scan quality.

Minor debris can accumulate on the white document lid backing located underneath the product’s 
lid.

Turn off the product, unplug the power cord from the electrical socket, and raise the lid.

If you have a 220V product, turn off the power switch.

Clean the white document lid backing with a soft cloth or sponge slightly moistened with a mild 
soap and warm water.

Wash the backing gently to loosen debris; do not scrub the backing.

Dry the backing with a chamois or soft cloth.

Do not use paper-based wipes as these may scratch the backing.

If this does not clean the backing well enough, repeat the previous steps using isopropyl 
alcohol, and then wipe the backing thoroughly with a damp cloth to remove any residual 
alcohol.

In certain areas of California, air pollution control regulations restrict the use of 

liquid Isopropyl Alcohol (IPA) as a cleaning agent.  In those areas of California, 

please disregard the previous recommendations and use a dry, lint-free cloth.  

The cloth may be moistened with water if desired.
