Hi, Jonh
i have the same problem:
after chipless solution with your firmware and noninkupdater
printers (wf 5710) stops printing or or start double printing on same text
i think you are changing a small wrong part at the firmware
The problem ocure after updaeting with your key.
i have in my warehouse 50 pieces wf 5710 which are now useless if we can not fix these problems. I am renting printers.
please replay what to do.
