The 6515 device is not EIP compatible which means it does not support Apps and therefore will not be able to be added to Xerox App Gallery.
Device Xerox WorkCentre 6515 (set up on both Ethernet & Wi-Fi)
unable to add my Printer on Xerox App Gallery with Google Chrome.
Don't understand why printer does not appear...
Need help to add Device on Xerox App Gallery.
