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.
When the arrow key is pressed, the color densities selected
with the color keys are collectively adjusted.
That is, all the density levels (points) from the low density point
to the high density point can be adjusted collectively.
When [EXECUTE] key is pressed, the adjustment pattern is
printed out.
The color balance at each density level (point) and the density
can be checked by referring to this printed adjustment pattern.
However, it is more practically to make a copy and check it.

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.
