If you know how to reset Xerox to factory default it will be solution too. I haven't a lot of user settings, so it will be easy to restore all I need.
It doesn't work:catindifferent: I deleted xerox from device manager (WSD scanner) and all it drivers, rebooted PC and printer and no, destination with my PC name is still in the list
If there is nothing in the Addressbook, and nothing in EPM from any of the devices you used, then TWAIN and or WIA was used, those would need to be disabled/removed from those PC's as no matter what you do at the printer, as long as it is on the same network location, those client PC's will keep pushing those templates to it.
Can't find how to delete destination list from printer?
When you want to scan to PC you should enter it, by default it's name of the computer, where EPM installed and configured. Unfortunatelly I didn't find any clear documentation about network scanning, so I created a few records from different computers, but finally I made virtual machine, so I don't need all list. I didn't find this list of records neither device menu, nor EPM, nor Web-interface.
