HP-97 printer
Message #1 Posted by Michel on 24 Sept 2004, 10:18 p.m.

Hi, i have a HP-97 that i want to change the printer head. I just tried with the HP-41 external printer head but when i try to print, the printer move but nothing print on the paper. I verify all connections and the ohmeter says all it's right... SO why i get nothing on the paper? Is the 97 and the 41 pinter head compatible ( except for the wire connector tha is longer thant the 97)?

Than you for answering my question.

The heads are NOT electrically compatible. The '41 printer uses a high impedance head driven by a higher voltage than the HP97 head.

Unless the break is in the flex cable itself there is no practical way to fix it. Only source of replacements is another HP97/91/92.
