  Epson XP-700 working fine till suddely get message saying 'ink pad at end of useful life - contact Epson Service' Epson service not interested as printer no longer under warranty and suggested best option would be to buy a new printer and scrap this one. So not a happy chappy and looked for options to try and resolve this issue. Found this site and downloaded reset program. WIN10 64bit PC connected to printer by WiFi. Ran reset utility - did not find any printers. Switched off printer and re started, disabled Epson Print Utility still no printer found. Rebooted PC and then after it had restarted tried the WIC Reset Utility again after connecting printer through USB. This time WIC found both connections WiFI and USB. Using USB took Reset option and purchased Key. Copied key into WIC utility and OK. Switched Off printer and then switched on and magic no error message and printer back to normal. Very pleased and somewhat relieved as have some printing to complete tonight before tomorrow morning. Very happy to pay £9.97 for this result.
