Acs (Auto Color Sensing) Mode - Ricoh J-P3 Service Manual

ACS (Auto Color Sensing) Mode

The machine can print in the color or monochrome mode (selected with the printer
driver). In the color mode, ACS can be switched on or off with a user tool (default:
on).
If ACS is on, the transfer belt stays in the default position (against the K drum only)
until a page with color data on it appears. The transfer belt then moves against all
four drums and stays there until the end of the job, even if some K only pages
appear.
If ACS is off and the color mode is selected, all data is printed with the transfer belt
positioned against all four drums. The belt does not move even if a K only page
appears, even if it is at the start of the job.
Regardless of the ACS mode setting, this machine counts a K only page as a
black-and-white page. Because of this, the K only pages (with the ACS mode on)
[A] and the K only pages (with the ACS mode off) [B] are each counted as black-
and-white pages.
