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.

I don't get any reply to my email. Is there a customer service person at the business? My question is: I see that you have the "HP OfficeJet G85 Service Manual and Parts List". How many pages does the manual have? Please answer my question by email, myccma@gmail.com. Thanks in advance.
