Have a look at the problem job and inspect the text with a magnifier to see if it contain color dots.

I don't see any color dots in the black text but I do see red and blue on the outsides of the black text with my magnifier that was a cheap lime green plastic thing. I tried a clear magnifier but it didn't zoom in that good but I could still see a hint of color on the very edge of the text.

I did see yellow dots when I zoomed in with my phone but only on the paper.

From manual if using PCL driver.
When you open the [Quality] tab and set the [Select Color] to [Auto Color], the image is automatically converted into gray scale and printed if the RGB values of the original are below the thresholds you have set. On the [Other] tab, check the [Convert to Gray Scale] box and set the threshold (the differential RGB values to be converted into gray scale).
Play a bit with threshold value.

This worked great for the PCL driver but the option doesn't seem to exist for Post Script.
I need a Post Script solution for the macbook users and for post script drivers in general for these 4e series.

The color dots means full color so i agree with you that if from other applications the counter works fine an adobe setting is the problem.
There where you could adjust (0,0,0,100) try making that value 255 not sure about AI settings...

Know that makes no sense i just try every thing.

Any color dots on the MSword job?

Can't set black over 100 (error: value must be between 0-100)

No yellow spots on word document

I'd like to think it was just an Adobe issue but the fact that it prints perfectly to a C552 is puzzling.

Those yellow spots are likely hidden machine identifiers.

I figured they were something like that.

I tried to go into Service mode to look for Engine FW Dipswitch but can't find it on a c364e.

Enter service mode then go to enhanced security mode there you will find the setting.
Enter service mode then stop 0 clear.

Oh, I see, it says "Enhanced Security" at the top...I don't see the Engine FW dipswitch though.

I guess the FW dipswitch doesn't really matter too much because I don't see these settings changing the Post Script drivers threshold any.

I was able to get around this issue with the PS driver but I had to export to b&w pdf's, open in photoshop as grayscale, save and then place each page back into a new indesign document and then paste in the color page. Just doesn't make sense why it works fine on older machines.

Does just a standard .txt document file with black text count a black click correctly??? If so, it sounds like it boils down to Adobe and how color space is managed and passed on to the driver and therefore counted. I had a similar issue at a lawyer's office that was using Wordperfect...the software actually overrode the print driver, so even if the system default was black, the Wordperfect setting for color actually overrode the system driver default!!! ANNOYING!!![emoji35]

Yes, a standard .txt or .doc file prints correctly. Did you ever find a fix for your wordperfect issue?

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 so I will follow up with that today.

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