Changing Image Contrast
on Prints
To achieve different tones on printed copies from those of
an original, adjust the scanning contrast manually by
canceling the Auto Scanning Contrast Adjustment mode.
The Auto Scanning Contrast Adjustment mode is
NOTE
available only for the Line processing mode.
However, this mode is not available with the
Bound Original feature even when the Line
processing mode is selected.
When the Auto Scanning Contrast Adjustment mode is
A
selected, is highlighted in the [Scanning Contrast]
frame and [Line (Auto)] appears in the [Image Processing]
frame in the Main Display.
In this case, the scanning contrast will be adjusted
automatically according to the darkness of the original
scanned.
Press the SCANNING CONTRAST
Adjustment Key in the Sub control
panel.
The [Scanning Contrast] frame indicates the contrast
currently selected.
Each time the key is pressed, the contrast changes in the
following order:
Auto Light
A
For newspaper or colored originals.
For poor copies or pencil-written originals.
NOTE
After adjusting the scanning contrast, make
another master to make the adjustment effective
for further printed copies.
Holding down the RESET key longer than one second
returns the Scanning Contrast Adjustment mode to
the initial setting.
☞ p.62 ....Scanning contrast can be adjusted and saved
