The raised cam holds the ITB at position
The machine automatically adjusts the paper feed timing for full color copying with all
the drums.
While the Y, M, C drums are separated from the ITB, they do not turn. This reduces
wear on these drums while they are not being used.
When Black-and-White Mode is Selected:
The motor turns the cam until the actuator goes out of the ITB lift sensor.
The motor stops.
With the left side of the ITB down, only the black (K) drum contacts the ITB.
The machine automatically adjusts paper feed timing for black-and-white copying with
only one drum.
The ITB stays down until the next full-color job starts
When ACS Mode is Selected:
⇒
If the job has color pages and black-and-white pages, the ITB operation is controlled
by SP 3930.
The default is 0 (low productivity). In this mode, the ITB changes position each time the
page type changes. This makes printing slower, but decreases wear on the color
PCUs.
If you set the SP to 1, then the machine will not move away from the color PCUs if a
black-and-white page is next. This makes printing faster, but increases wear on the
color PCUs.
