Product: T739
I have a designjet t730 in for repair.
The printhead is not seen, saying missing damaged or not seated correctly.
It was replaced with a new one, but this made no difference.
I then installed a known good head.
Again no progress.
I then took a known working carriage board off a machine installed and tested it.
Again no progress. Same error.
I'm thinking there is only the main board or the trailing cable left.
Machine boots ok carriage moves across etc etc.
I did a oobr - no change
Any advice
Thanks
