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.

The procedure was easy. I used the trial version, and my printer is now working. I will buy the reset key next time. I recommend this fix. Thank you....

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.
