There is no M15 driver for Windows 10 , or 8, or 7, it is long since dropped out of development.
You have a few choices, Install the Xerox Global PCL driver and use it in Basic printing Mode
Or disable driver signature enforcement and try installing an older driver like the Server 2008 one or the Vista 64bit.
None of the options are official.
I can't install my WorkCentre M15 on a Windows 10 computer.
When I connect the M15 to the computer, Windows recognized it, but shows a warning that driver is not available, so, I can't use it as a printer.
I downloaded and executed all files offered on xerox page, but nothing worked.
What can I do? Does anyone knows how to solve this?
Attached is an image of windows warning (it reads: "Driver not available")
