HP82143A Repair - Paper Advance and Round O-rings
Hello,

I would like to share my experience with repairing the paper advance rollers for my HP82143A thermal printer. Thanks to some members I was informed a good replacement for the rubber rollers on the paper advance mechanism for this printer, which were square profile o-rings. Unfortunately they seem to be non existent here in Brazil so I ended up using round profile ones. I've installed two on each side of the shaft and then put a tiny amount of glue on the o-ring edges. Attached is a picture of how it looked like.

So far I tested the printer with original HP thermal paper as well as a new roll of thermal paper that is used for credit card machines. I used all 25m of it with no issues so far.

Best regards.
