Color Control
This function is used when necessary to reduce the image size on the printed page
due to paper shrinkage during printing. It uses the set-up value to reduce the
printed image. For the front engine the reduction of the image for the horizontal
direction can be 0%, 0.12%, 0.24%, 0.36% or 0.48%. For the rear engine the
reduction of the image for the horizontal direction can be 0.12%, 0.24%, 0.36%,
0.48% and 0.60%. For both the front and rear engine the reduction of the image
for the vertical direction can be from 0 to 1.00% in increments of 0.01%.
Before this function is used, the print position must be adjusted vertically and
horizontally. Refer to Setting the Tray Adjust values for adjustment of print
position.
The screen display is based on whether the print mode is simplex or duplex.
In the case of simplex mode, the reduction value is fixed at 0% for the front side
in the front engine because the paper does not shrink. The value needs to be set for
the front side of the rear engine only.
In the case of duplex printing when the paper length is 9 in. or less, the printing
sequence is as follows: Front side/front engine > back side/front engine > front
side/rear engine > back side/rear engine. Therefore, the reduction value should be
set at 0% for front side/front engine > X% for back side/front engine > X% for
front side/rear engine > X% for back side/rear engine.
In the case of duplex printing when the paper length is over 9 in. (Letter SEF, A4
SEF, etc.), the printing sequence is as follows: Back side/front engine > front side/
front engine > back side/rear engine > front side/rear engine. Therefore, the
reduction value should be set at 0% back side/front engine > X% front side/front
engine > X% front side/rear engine > X% back side/rear engine.

If the paper size or direction is changed, the image may not be printed
correctly. Reset the reduction value.
