HP-82104A Card Reader Repair Questions

[Hiwi]

Hi Tony,
my experience is, that the speed of the cardreader is not the main problem. It works in a great range.

If you record a card and read it again and it gives card errors there may be other issues, that could be
some tantalum caps or the CRC Chip.

If adjusting the pinch roller will not be successful check the waveforms or ripple of the supply voltage.
