Selecting Image Quality - Canon imageRunner 2220i User Manual

Selecting Image Quality

You can manually adjust the image quality to the level best suited for the quality of
text or photo originals. The following three modes are available for adjusting the
image quality.
IMPORTANT
•
You can select only one of these modes at a time. If you select one of these modes, the
1
previously set mode is canceled.
•
If you scan an original containing halftones, such as a printed photograph, the moiré
effect (a shimmering, wavy pattern) may occur. If this happens, you can lesson this moiré
effect by using the Sharpness mode. (See "Adjusting the Contrast (Sharpness)," on p. 1-
129.)
NOTE
•
If you select the Text, Text/Photo or Photo mode, the scanning exposure can be adjusted
only by Manual Exposure Control. Automatic Exposure Control cannot be set.
•
If the Photo mode in Communications Settings is set to 'On', you can select [Printed
Image] and [Photo] after pressing the drop-down list. (See "Setting the Photo Mode
(Photo Mode)," on p. 3-8.)
If the original is a transparency, select the Text, Text/Photo or Photo mode © adjust the
•
exposure to the most appropriate level for the original.
