2)
Select the copy mode to be adjusted with the scroll key.
3)
Enter the adjustment value with 10-key and press [OK] key.
When adjusting the copy density on the low density part, select
"LOW" mode and change the adjustment value. When adjust-
ing the copy density on the high density part, select "HIGH"
mode and change the adjustment value.
When the adjustment value is increased, the copy density is
increased. When the adjustment value is decreased, the copy
density is decreased.
When adjusting the copy density on the low density part, select
"LOW" mode and change the adjustment value. When adjust-
ing the copy density on the high density part, select "HIGH"
mode and change the adjustment value.
When the adjustment value is increased, the copy density is
increased. When the adjustment value is decreased, the copy
density is decreased.
4)
Press [CLOSE] key in this simulation mode to jump to the nor-
mal copy mode. Make a copy and check the adjustment result
Switch the simulation mode and the normal copy mode alter-
nately, and adjust and check the adjustment result.
Repeat switching the adjustment mode (SIM 46-1) and the
normal copy mode and changing the adjustment value and
checking the adjustment result until a satisfactory result is
obtained.
To increase the density, increase the adjustment value. To
decrease the density, decrease the adjustment value.

adjustment) (Normally unnecessary to
adjust)
This adjustment is needed in the following situations:
* When there is necessity to change copy density of the low den-
* When there is necessity to change copy density of the low den-
sity and high density part at each copy mode individually.
* When there is necessity to change the density gradient of the
copy by each the copy mode individually.
* When there is necessity to change all copy density by each the
copy mode individually.
* U2 trouble has occurred.
* When the MFP PWB is replaced.
* When the EEPROM on the MFP PWB is replaced.
The density is adjusted in each copy mode individually. Normally
individual adjustments are not required. When there is a request
from the user, execute this adjustment.

NOTE: MODE1:
High gamma (Improves the image contrast)
MODE2:
Normal gamma
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 con-
stant 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.)
PRESCAN:
The densities of the all surface of document are once
scanned, and the output 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
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
Operation in monochrome auto copy mode:
When the density of the document of the read area is light,
output image density is increased by control. When the
density of the document of the read area is dark, output
image density is decreased by control.
MODE2:
Normal gamma
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 con-
stant 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.)
PRESCAN:
The densities of the all surface of document are once
scanned, and the output 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
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
Operation in monochrome auto copy mode:
When the density of the document of the read area is light,
output image density is increased by control. When the
density of the document of the read area is dark, output
image density is decreased by control.
