HP Thermal Printer Paper Advance Repair

[Hiwi]

Hi all,
some years ago I got many NOS paper advance rollers for the repair of the HP-41 thermal printers from a former HP dealer here in Hamburg/Germany.

But they are not usable anymore because the gum is destroyed as well.

So i decided to use as an alternative silicone tube. I did this reapair successfully now for more than 15 printers. This covers the HP82143, the HP82166 and the HP-97.

Many HP power users are repairing cardreaders theirself but are afraid of repairing the printer.

But it is basically the same thing and not a rocket science.

I made a brief descpiption of the things to do.

May be this will help others.

Excellent - maybe the document should be copied or moved to the "Articles" Forum section?

Nicely done. One tip for cutting a thin section of tubing it to push tubing onto a wooden or plastic dowel rod first.

I used a small drill press with a drill of the right size inside the tubing and used a blade against the rotating side of the tube. It takes a bit more time but produces a nice result. Some pictures on page 41 of my Classic Notes.

Great suggestion, I'll move it there now (but of course if you're reading this, you knew that).

Thanks Martin!
