Clean the device
During the printing process, paper, toner, and dust particles can accumulate inside the product. Over
time, this buildup can cause print-quality problems, such as toner specks or smearing. This product
has a cleaning mode that can correct and prevent these types of problems.
Clean the exterior
Use a soft, damp, lint-free cloth to wipe dust, smudges, and stains off of the exterior of the device.
Clean the scanner glass
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.
NOTE If streaks or other defects appear only on copies produced using the automatic
document feeder (ADF), clean the scanner strip (step 3). It is not necessary to clean the
scanner glass.
1. Open the scanner lid.
2. Clean the glass by using a damp, lint-free cloth.
CAUTION Do not use abrasives, acetone, benzene, ammonia, ethyl alcohol, or carbon
tetrachloride on any part of the device; these can damage the device. Do not place
liquids directly on the glass. They might seep under it and damage the device.
3. Clean the scanner strip by using a damp, lint-free cloth.
