Re: HP 41 CX cardreader problem Message #3 Posted by Hal Bitton in Boise on 5 Sept 2008, 5:03 p.m., in response to message #1 by Matti Övermark
Hello Matti,
More than likely the drive wheel material in your card reader has broken down, and deteriorated into a gummy sludge. This is a common problem in the card readers of all early HP machines and is due to age.
There are two sets of directions (from two different people) that describe the repair procedure here.
Good luck, and best regards, Hal
