  Absolutely brilliant , this small utility saved me from having to replace my Printer. Had I known of this sites existence previously I am sure it would have saved my Epson 580 which I just through out.

  I have modified the firmware of an Epson wf3620 with the firmware key to make the printer run with chipless ink cartridges. The instructions were clear but must be followed exactly in order for the process to be successful. I am very happy with the result as I have the freedom to use oem ink or not depending on my needs. No oem cartridges now work perfectly well. Well done wic utility people. regds, Peter.
