Setting Recommended use
Color Use this setting for high-quality color photos or documents in
which the color is important.

Grayscale Use this setting when file size is an issue or when you want a

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