I have a C5540 color copier.
I set up two printers on our server. One B&W and one Color. Most users only have access to the B&W.
Most of the time it it does exactly as it should where it prints 100% black toner.
However once and a while, the device prints color objects. I've noticed this most with word documents that have colored boarders around images. I used the B&W driver so it doesn't even have a color option on the printer. In the image below you can see that the photo I took of the print out made the images back and white but kept the red boarder as seen in the original screen shot in the upper left.
How do I stop this? I need it to stop as these count against our color copy allowance provided by the lease.

I was able to determine that this only happens on machines with Windows 11 in turn, a driver issue. Our local dealer that provided the printer is either unable or unwilling to report this to Canon. One thing is for certain, we are going with Sharp for our next copier. I did not have these issues with that company.
