HP-19C Repair Odysee

[Jonas Sandstedt]

Bernhard, I have to agree that it is an awesome collection. I hope that you one day have time to share how these HP-19c units work and what measures that have to be done to fix possible malfunctions.
Regarding printheads, I ordered a couple of TH102-E printheads which were received today. The TH102-E is used in the Seiko printer MTP-102 that is adapted for 38mm paper width, the printhead TH201-E used in the Seiko printer MTP-201 that is adapted for 57mm paper width was unavailable. I guess the only difference is the length of the flex cable. As mentioned previously, MTP-201 is used in for example the HP-82240A/B.
I enclose some pictures of the printhead, unfortunately it is glued to a plastic holder, and the flex cable is shorter than the one used for the HP-19c. As you can see, the printhead is not as wide as the one used for the HP-19c. I have not figured out how to use the printhead, or even if it can be used, but wanted to share the pictures for information purposes.
Best regards Jonas
