2) Set REALTIME, STOP or PRE-SCAN to adjustment item AE
STOP COPY. For contents of each setting item, refer to below.
Change the setting value of "AE WIDTH" item to "FULL" or
"PART", in some cases.

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.
