Well I finely received all the parts that I needed. I replaced heater junction board, heater control board,Ink board id assembly and motherboard that I had and also replaced ink cartridge. Replaced new cards supplied by Mutoh still all cartridge read ink not original. I don't know what else to replace or do.
Check the r45 cables, seems to me they run from the junction board to the heater and then the motherboard.
If they are switched at the heater, it should give a com error, but maybe....
