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 den-
sity 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 output image density is determined according to the
average of the scanned densities. (The output image density is
even for all the surface.)
In addition, the original type is automatically determined and the
processing is carried out in an optimum original mode.
AE WIDTH FULL: Document density reading area in monochrome
auto mode is 3 - 7mm (leading edge of document) x Document
width. No relationship to PRESCAN MODE

auto mode is 3 - 7mm (leading edge of document) x 100 mm
(width). No relationship to PRESCAN MODE
STOP: Reads the density of 3 - 7 mm area from leading edge of
document, decides the output image density according to the den-
sity 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 output image density is determined according to the
average of the scanned densities. (The output image density is
even for all the surface.)
In addition, the original type is automatically determined and the
processing is carried out in an optimum original mode.
AE WIDTH FULL: Document density reading area in monochrome
auto mode is 3 - 7mm (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 - 7mm (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.
When the density of the document of the read area is light, output
