HP 9872T Trouble Shooting

[husmann]

I’m giving up. After having spent (again) quite a few hours analyzing the defective electronics of my HP-9872T I come to the conclusion that it is time to withdrawal. I do not have neither the equipment nor the time budget to continue this quest. Thanks to all who helped me.

If someone has interest in this HP-9872T: I give it away for free – complete with one spare paper roll, the service manual, the operating and programming manual, and the quick reference guide (no cables, no pens, 240 V AC).
