Procedure 2: Modifying the ACS switch setting
Modify the following SP to minimize the idling operation time of Y, M and C
developer units, if color images show more mottled effects compared to mono-
chrome images.
SP MODIFICATION
Why Y, M and C?
Y, M and C development units tend to idle more than the Bk development unit. This
is because, by default, these units are designed to continuously run idle even when
the printing mode switches to mono-chrome from full-color. Y, M and C
development units remain inactive only if printed in mono-chrome mode throughout
the entire operation, from startup to stand-by.
SIDE EFFECT
Productivity will slightly decrease because it will take approximately 5 seconds to
switch from FC mode to mono-chrome mode, and approximately 7 seconds in the
reverse order.
Also, it will take an extra 2~3 minutes to perform Process Control, if turning on the
machine power or resuming operation after a long pause in low temperature
environment.
Enter the following SP and change the value from “0” (default) to “10”.
