ACS is auto color Selection
This applies to copy only
On many color devices like the 7000cmf(without ACS), as soon as the system outputs a color page all subsequent pages are developed with all 4 developing units and it is counted as a color pages even if the page is black and white. Black is still made with the black toner only (not process black) but it clicks the color meter.
In short a system with ACS, like the 2232/38, will click the color meter when it outputs color and click the bw meter when it outputs bw regardless of the situation. Works just as you would expect it to.
The “problem” currently is if I tell the 2238 to require a user codes to copy in full color the system will not let me select ACS. If I would then copy a 10 page document with the first page color the rest BW it would count them as all color. Just like the 7000CMF.
Ricoh is aware of this issues and hopefully going to fix it.
