Re: HP97 Printer idler gear. Message #3 Posted by Etienne Victoria on 6 Apr 2006, 2:24 p.m., in response to message #1 by Ignazio Cara Hello Ignazio, If you're located in Europe and if your request is about a broken idler gear (the ugly whitish plastic lego-like part), I suggest you follow Jürgen's advice posted here. I purchased 10 of these gears, drilled carefully the center to axis dimensions and successfully restored many 9x printers this way. GHW is a very nice and helpful person. Good luck!

Basically, this horror: The GHW gear is as follows: And it is very robust though quite easy to drill. Nelson, you have mail. All the best from France. Etienne Edited: 6 Apr 2006, 3:22 p.m.

Re: HP97 Printer idler gear. Message #6 Posted by Nelson M. Sicuro (Brazil) on 6 Apr 2006, 6:47 p.m., in response to message #4 by Etienne Victoria Yes, this is the "beast"... I can't imagine what kind of plastics this gear is built of. It "desintegrated" in my hands! Ok, 30+ years is a lot of time for a plastic gear to keep working... why a plastic one and not a metallic one? Damping of the motor's vibration? Now I need to find a suitable 0-ring to repair the card reader :) and become a proud owner of a full-restored HP-97! Best regards, Nelson from Brazil
