I managed to rebuild a 97 out of two defect units. One problem however leaves me clueless: The printer heads of both 97 units have broken flex wires (the thin flat wire band connecting the printer head to the driver pcb), and all attempts to solder regular wires to the flex band failed. If anybody has a hint on how to fix this, it would be most welcome, however my last desperate attempt would be to use a 82240A printer head. I have never opened an 82240A unit - does anybody know if such an operation would be feasible, i.e. if the 82240a head is compatible with the 97 head and if its connection is similar?
