I upgraded the Firmware on a WF-5710 successfully. I gave the printer to a non-profit and when trying to install the printer at their location, It wouldn't recognize the ink cartridges.
I tried to update the firmware at their location, the printer is on a network and wasn't recognized. When I brought the printer home to attempt another Chipless Conversion and I now
receive the message to "Please Update Our Firmware", I figured there may be a newer version, I downloaded the firmware for the WF-C5710 again and attempted to upgrade and still receive the "please update our firmware" message. Any ideas?
