HP-82104A Card Reader Repair Questions

[Papymouzot]

Dear All,

I wish you first a happy Easter break !

Then some news… I don’t know why but I really found useful to open the working reader to swap the card unit/1motor, with the electronics of another non working unit.

Result: I ordered the caps for nothing. The Card err message seems to be coming from the card/motor unit ???

The unit which is working is a bit sensitive though, I got scared when I reassembled it… I also had in a few occasions the card err message, but after 3/4 attempts I finally had « working » and subsequent tests of writing /reading worked fine.

Next… find why the card/units don’t work…. ??
