MX-7040N ADJUSTMENTS AND SETTINGS 5 – 55
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 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.)
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.)
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

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 doc-
ument of the read area is dark, output image density is decreased
by control.
