Absolute lifesaver. Saved me about $100 and 2 hours driving.

I purchased four activation keys total, but I had an issue using one. John at tech support got it straightened out and I was able to complete the install on the printer. Now I can set up the CISS unit for Sublimation printing. I'm very happy, and can testify that this product works to unlock the firmware of your printer. (Epson WF-3720)

Ich bin begeistert! Mit dem TRIAL Key konnte ich meinen Epson XP 750 wieder resetten und er funktioniert wieder. Vielen Dank, dass ich mir dadurch das Geld für einen neuen Drucker sparen konnte und ein Drucker weniger die Umwelt belastet. War nur etwas anstrengend, die englischen Anweisungen zu lesen und zu übersetzen. Es wäre schön, wenn es diese Seite auch auf Deutsch gäbe.

An excellent service that works. Don't be fooled by the printer manufacturers that you are trapped into buying their over priced cartridges because you thought you were doing the right thing by upgrading the firmware. The only reason for their upgrade was to stop you from using your own cheaper 3rd party ink cartridges. If you accidentally did do the upgrade as they recommended don't worry as you can undo that costly mistake with the help of "wicreset". It really works. Also did you know that 3rd party cartridges actually contain around 25% more ink than oem cartridges?

Hi, I'm particularly satisfied of the Wic Reset Utility I just used for the 3rd time (2020, 2022 and now) for my Epson WP635 Printer. I had felt pads left from the last time, easily replaced them thanks to the excellent instructions found on octoink's site, then bought a new key and re-intitialized my printer in minutes. My printer is now renewed for 2 years! Very very satisfied. Many thanks. MF, France

Veramente efficace e veloce. Sono pi� volte che utilizzo il programma WIC e mi sono trovato sempre bene. Certo, bisogna svuotare la vaschetta di recupero dell\'inchiostro. Se no...
