Function
(Purpose)

Used to set the fusing capability (image process) in the
heavy paper mode. (AR-C150)
Used to select the gamma characteristics in the color
copy mode. (AR-C250/C160/C270)

Operation

Operation/
Procedure

(AR-C150)

Press the ENABLE or the DISABLE key to set.
This simulation is used to give priority to the fusing
capability over the image quality in color copy with
heavy paper.

The quantity of black toner which forms images on the paper is re-
duced in the image process to have better fusing.
It is advisable to use this setting when poor fusing results from
color copy with heavy paper.

When ENABLE (priority to the fusing capability over image quality)
is selected, the black density is slightly reduced to shift the color
phase. Normally set to DISABLE.

Setup

Operation/Effect

Default

ENABLE

K toner is reduced and the black
reproduction is supplemented by
Y/M/C toner in image process./Fusing
capability is increased when heavy
paper is used.

In some AR-C100/C150 machines with an old ROM version,
this simulation is added from the middle of the production. 
In the AR-C150 machines with an old ROM version, upgrading
of the ROM version allows to perform this simulation.

Press the ENABLE / DISABLE key to select. 

This is used to set the order of priority between sharpness and
gradation in the color copy mode. Setup is made by changing the
gamma in the high density area.
