This update helps to recognize compatible cartridges or continuous system with self-resetting chip that I stopped recognizing due to firmware update in Epson WF-7510 Printer.

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.

I have order it but it can not work for reset wast ink pad. When release a new it too sad to order with 19.99$ with nothing can do. ====REPLY==== This printer model has separate Waste Ink Maintenance Box with its own IC chip. You can replace Waste Ink Maintenance Box or reset the chip on the Waste Ink Maintenance Box. This information is clearly stated in program description at our site.

I replaced the waste ink pad assembly on my Epson XP-800, not understanding that there were internal counters needing to be reset. The WIC Reset Utility and the WIC RESET KEY, along with the replacement waste ink pad assembly, have restored my printer to me. Thanks for making it so easy and, most importantly, having it work like you said it would.
