HP 82240a printer barely advancing paper

[ls41028]

I had a similar problem on my HP97, which has a similar paper feed mechanism. The problem turned out to be a small piece of thermal paper down in the feed mechanism. I pulled the roll of paper out, fished the little piece out with a bent paper clip, and it was all back to normal.

If that isn't it, look for posts on the drive gear on the 97 desktop calculator. As I said I believe the 82240a is similar in design.

Good luck!
