"050 - ACS mode can be changed to limit the amount of time that the color IUs run. When the new mode is selected, the printer works as though doing monochrome printing without driving the color IUs."
What should be the value?
How is life in Kharkiv? Hope all is well.
First there is Engine firmware dipSW 25 that is OFF for production priority and ON for parts life priority. In the OFF state the primary transfer rollers never retracts* for ACS copy or Auto Color for print if the job is mixed B\W and color. In the ON state it will retract if a given number of consecutive B/W pages was detected but only after the second set for copy mode. It needs to get the histogram data from the first set but it does not wait and starts printing immediately without knowing if the pages in the first set are B/W or color.
ACS needs 4 or more consecutive B/W pages to switch to K rotation only and always starts in CMYK rotation for the first 3 pages regardless if they where B/W. Base on 45ppm.
SW 50 HEX00 : Production priority (less print interruption)
SW 50 HEX01 : Parts life priority (more print interruption)
So Engine firmware dipSW 25 to ON and SW 50 HEX01. The machine will be slower with interruptions in the print job.
The machine is default set to Engine firmware dipSW 25 to OFF and SW50 does not seem to apply?!
Whatever

Here is another one to add. Software SW 24 Hex 01, prevents machine from printing a blank page on custom PCL print job because of a form feed command. Works on everything from C220\C452 series up to I series.
