Hello fellows,
who can help me to find and purchase a spur gear for my HP 97 printer? I have tried at Pic-design but with few luck. I will refund in advance all your costs.
Thanks a lot for your help.



I have the very same problem, if you found more than one i'm interested in 1 piece.

Best regards,

Nelson Sicuro

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 J├╝rgen'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!

Hi again, Ignazio & Nelson,

I've put a few images of my 9x repair here to make sure we are talking about the same thing.

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.

Thank you, Victoria, for your advice.
I've need of this gear, exacltly.

Best regards from Italy,


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

Hi Nelson,
If GHW send me soon the spur-gear I could send you a gear and a couple of o-rings for your HP-97.

Best regards

Can anyone kindly send me one of those gears? I am not good at modifying them. I would pay whatever reasonable amount you ask. Thank you.
