MX-C250 ADJUSTMENTS 5 – 39
2)
Set “MODE” or “STOP” to adjustment items. For contents of
each setting item, refer to below. Change the setting value of
"MODE" or "STOP" in some cases.
MODE1: High gamma (Improves the image contrast)
MODE2: Normal gamma
LAEADING EDGE STOP:
Reads the density of 3 - 7 mm area from leading edge of document,
decides the output image density according to the density of that
part. (The output image density is constant at whole area.)
REALTIME:
Reads the density of width of the document one by one, decides
the output image density according to the density of each part of
the document. (The output image density may not be constant
through the whole document.)
Operation in monochrome auto copy mode:
When the density of the document of the read area is light, output
image density is increased by logic. When the density of the docu-
ment of the read area is dark, output image density is decreased by
logic.

Document low density image density
reproduction adjustment in the automatic
(Copy/Scan/FAX) mode
(No need to adjust normally) (Background
density adjustment in the scanning section)
Use for the reproducibility adjustment of document background
density in auto mode.
This adjustment is required in the following cases.
* When there is a desire not to reproduce the background of the
document. When there is a desire to reproduce the low density
image of the document.
* When there is request from the user.
1)
Enter the SIM 46-32 mode.
2)
Select the adjustment mode with [UP] or [DOWN] keys.
3)
Enter the adjustment value with 10-key and press [OK] key.
When the adjustment value is increased, reproducibility of the
background and the low density image is increased. When the
adjustment value is decreased, reproducibility of the back-
ground and the low density image is decreased.
9-H
Color copy simple density adjustment
Adjustment 1
The gamma and the density of Text, Text/Printed Photo, Text/Pho-
tograph mode is to be changed. With this adjustment, the total
density and the contrast can be varied.
This adjustment is required in the following cases.
* When the reproducibility is to be changed.
* When there is request from the user.
1)
Enter the SIM 46-27 mode.
2)
Select the mode to be adjusted with [UP] or [DOWN] keys.
3)
Enter the adjustment value with 10-key.
When the adjustment values of item A, C and E are changed,
the gamma at the total image is changed.
When the adjustment value is increased, the image contrast of
the total image is increased. When the adjustment value is
decreased, the image contrast of the total image is decreased.
When the adjustment value of the adjustment item B, D and F
are increased, the image density at the total image is
increased, and vice versa.
4)
Press [OK] key.
5)
Check the copy.
If a satisfactory result is not obtained, return to the SIM 46-27
mode and change the adjustment value.
Repeat the above procedures until a satisfactory result is
obtained.
