I have 2 printers WF-7710, I bought chipless keys
One printer I chipless mounth ago and remove all chips (cartrige+maintenance box) and perfect work without chips
Week ago I chipless second printer and remove all chips too (cartrige+maintenance box), but he work only 5 days and blocked
Now he show cartrige ink full , but maintenance box 0%
Dear John, can you fixed this bug in chipless firmware ?
