Re: how to fix a hp41 card reader? Message #3 Posted by Gerry on 8 Sept 1999, 5:50 p.m., in response to message #1 by thib
If "traces" are a kind of gooey film left on the cards, then you've got a deteriorated pinch roller. I fixed this myself a month ago. Go into the HP Forum archive and follow the "thread" of Wayne Brown's post of 10 April 1999 and Steve Borowsky's post of 17 April 1999. They had excellent instructions on how to get into the card reader and make a new roller. I used Steve's method of using two O-rings. I think that material is more robust and can be found at any good hardware store. Cheaper, too, than buying a few feet of model airplane hose.
