I have a couple of HP 41 card readers. Both started having trouble recently. The cause is that rubber wheel that disintegrates with age. Two cards I used came out with rubber sticked to them.

Can anybody out there supply me with spare rubber wheels? I would appreciate it.

Thanks.

Take a look at the article below. It talks about how to fix this problem.

Victor:

Thanks a lot.

I recently repaired my card reader, had the same problem with "gummy wheel". I first put (2) #006 O-rings, and the reader would not read a card. So I replaced them with #005 O-rings and it works as good as the day I bought it.

Regards Ron.

Ron:

Thanks. One of the readers gave up after 20 years, the other after 18 years. Lasting value, as HP liked to say.

I still have to sit and repair them.

I'll keep you posted on my progress.
