The driver is from 2010, certainly isn't signed to work in Win 10, so to use it, you likely need to Disable driver signing enforcement on the PC
Queried Google and found digital file signature must be turned off temporairly for Windows 10 to install printer driver - access instructions via Windows search bar.
I add a printer - create a new port - standard TCP/IP Port - enter IP address - uncheck Query printer ... - Select Have Disk - ( I downloaded the latest Windows 10 64 bit driver from Xerox Web site - unzip) - Select - fxezui.inf - Select Xerox 6204 Wide Format - Next - accept Printer name - Next - installing printer - allow app to make changes to your device - Yes - installing printer - ....... it now cycles back to Printer name,
I have tried installing printer as a local admin on the PC and a domain admin on the PC - same cycling occurrs - redownloaded drivers - same cycling. Please advise.
