All Bizhub C224e through C754e All printing Full Color when Auto Color is selected

[tsbservice]

I have been working with the Adobe community to try to resolve this as well and the conclusion there is that the Print Driver/Printer is converting the black to 4 color. I Can do Output previews and it shows as pure black and no CMY at all but if I hit print....Color click under auto color. I started a ticket with Konica last week but have heard absolutely nothing back yet.

Note: I am now testing this on a C658 and having the exact same issue.

To me it looks like you are doing terrific job.
Thank you and keep us informed.

It finally prints properly!

Here's what I think did it:

1. Installed FW A5C10Y0-F000-G20-M0 (Has fix for auto-color issue but needed more help)
2. Change Software Switch 59 to hex 01 (Makes the Engine FW DipSW setting button appear in Enhanced Security screen in service mode)
3. Select #25 in the Engine FW Dipswitch settings (ACS parameter: sets the black printing quantity threshold until switching the transfer belt from all press to K press when a few pages of black printingis included in color printing)
4. Indesign Print Setting: Output color = Composite Leave Unchanged
5. Indesign Preference: Appearance of Black = Output all blacks accurately

On the 8 series, I did steps 2-5 and it worked as well.
