Selecting Image Quality (TEXT, TEXT/PHOTO, PHOTO)
You can adjust image quality to the appropriate level best suited to the quality of text or photo originals.
The following three modes are available for adjusting image quality.
■
TEXT
This mode is best suited for making copies from text originals (600 dpi). Good-looking copies can be
made from even blueprints or faint pencil-drawn originals.
■
TEXT/PHOTO
This mode is best suited for making copies from originals containing both text or photos, or photo
originals containing halftones (i.e. printed photos).
■
PHOTO
This mode is best suited for making copies from photos printed on photographic paper. (200 dpi)
NOTICE
●
If you make copies of an original containing half-tones such as a printed photograph using the Photo mode, moiré
may occur. If this happens, you can soften this moiré effect by using the Sharpness mode. (See ”Making Sharp
Contrast Copies,” on p. 5-17.)
●
Combinations of these three modes cannot be set. If you select one of these modes, the previously set mode is
cancelled.
MEMO
●
When the Photo mode in the Custom Copy Settings is set to [ON], [PHOTO] is displayed. (See ”Photo Mode,” on
p. 8-8.)
●
When you have selected the Text, Text/Photo or Photo mode, the copy exposure can be adjusted only by Manual
Exposure Control. Automatic Exposure Control [A] cannot be selected.
●
If the original is a transparency, select the Text, Text/Photo or Photo mode to adjust the image quality to the most
appropriate level.
