RE: HP19c Printer Disassembly
I figured out how to disassemble the HP-19c printer (more details later). I've removed the thermal printhead and the measurements for the head are as follows, in case anyone has access to a similar 7-wire, thermal printhead. Fundamentally, the HP-19c thermal printhead is 6.37mm x 14.00mm. The 7-lead ribbon cable is 135.85mm long, including the gold contacts.
This particular HP-19c thermal printhead has 3 of the 7 thermal print pins are dead. Average resistance of a good thermal pin is 11.8 ohms from the pin lead to the ground lead, including the ribbon cable leads. Here is a picture of the printhead. |
