Monochrome copy density, gamma
adjustment (for each monochrome copy
mode) (No need to adjust normally)
Monochrome copy density, gamma
adjustment (for each monochrome copy
mode) (No need to adjust normally)
This adjustment is used to execute the density adjustment for each
density level in each monochrome copy mode.
density level in each monochrome copy mode.
This adjustment must be performed in the following cases:
* When it is required to change the gamma in each copy mode.
* When there is request from the user.
1)
Enter the SIM 46-16 mode.
2)
Select the density level (point) to be adjusted with the scroll
key.

3)
Enter the adjustment value with 10-key and press [OK] key.
When the adjustment value is increased, the density is
increased. When the adjustment value is decreased, the den-
sity is decreased.

The density at each density level (point) can be checked by
referring to this printed adjustment pattern. However, it is more
practical to make a copy and check it.

This setting is required in the following cases.
* When a proper density copy is not obtained in the monochrome
automatic copy mode.
* When a document with images near its lead edge is copied.
* When a document with colored background is copied.
1)
Enter the SIM 46-19 mode.

Change the setting value of "AE WIDTH" item to "FULL" or

NOTE:
MODE1: Normal gamma
MODE2: High gamma (Improves the image contrast)
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.)
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 be not constant at
whole area.)
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 be not constant at
whole area.)
PRESCAN:
Once the densities on the document surface are scanned, the out-
put image density is determined according to the average of the
scanned densities. (The output image density is even for all the
surface.)
Once the densities on the document surface are scanned, the out-
put image density is determined according to the average of the
scanned densities. (The output image density is even for all the
surface.)
AE WIDTH FULL:
Document density reading area in monochrome auto mode is 3 - 7
mm (leading edge of document) x Document width. No relationship
to PRESCAN MODE
Document density reading area in monochrome auto mode is 3 - 7
mm (leading edge of document) x Document width. No relationship
to PRESCAN MODE
AE WIDTH PART:
Document density reading area in monochrome auto mode is 3 - 7
mm (leading edge of document) x 100 mm (width). No relationship
to PRESCAN MODE
Document density reading area in monochrome auto mode is 3 - 7
