I have the same issue with the WorkCenter 6515 using Mojave or Catalina. Scan works on my old mac that uses macOS High Sierra.
That doesn´t change anything.
If I knew that, I would never have bought a printer from this company.
I used Image Capture to scan from the flatbed but get an error message if I tried to use the document feeder. So it has become semi-useful. Tried a couple of software/driver packages for other multifunction printers that have Catalina compatible drivers. No luck. In checking the existing drivers for 3215/3225 and similar printers are 32 bit and have been around since at least 2014. Really! All these years to upgrade to 64 bit and programers at Xerox have been sitting on their collective butts. If I had known this (and why would I) I would not have purchased the 3215 this past year.
Same here with WorkCentre 6515 on Mac OS X 10.15 Catalina.
I also have problem with printer and scanner. The printer not work properly and the scanner not working at all.
example, if i want to print 1 page, most of cases, print 10 pages with small symbols & letters.
The scanner not working at all, on macOS Catalina !
I don't want to dowgrade the macOS for make the *multifaction printer to work.
I bought six weeks ago, 3225 Xerox WorkCenter and my misfortune appeared at Macos 10.15 and scaner and the printers they stopped working. When Can I expect a new steer to Catalina? With respect.
I also have an issue with my 3225 scanner due to it not having the drivers for Catalina. Please update soon, so that I could use my scanner...
Need new drivers to use the scanner for a new 3215 printer and Mac OS 10.15.
