It took me 3 days and I finally figured out that I needed the epson original driver on my laptop. It had been using the windows print driver. This app worked to reset my counter on my epson ET4800.

Worked like a charm. eezy-peezy. This do-it-yourself project saved me the cost and set-up of a new printer; WIC Reset saved me the cost of going to epson for a more expensive reset. Thank you.

​Hi, ​I have an Epson SC-P10070 (T809 series) and want to remove the region lock to use T802 cartridges. ​Does your tool support unlocking or changing the destination code on the SC-P10070? ​Can it bypass or handle the anti-tampering / write-protection routines found in the latest firmware? ​Thanks in advance!

La verdad quedé bastante sorprendido con el resultado. Desde el primer momento todo fue muy sencillo y el servicio cumplió con lo que prometía. La calidad se nota, los detalles están muy bien cuidados y la atención fue excelente. Definitivamente lo recomendaría a cualquiera que esté buscando algo confiable y de buena calidad. Sin duda volvería a utilizarlo.
