Card reader head cleaning

[Raymond Del Tondo]

Hi,

if you can find an index card of the thickness of the mag cards, it should work.
Thicker cards may lead to kinda paper jam.

I'm not sure whether isopropyl alc. could damage the transport wheel or not.
If the transport wheel has been replaced, it could work w/o damage,
but if the card reader wasn't serviced so far,
I suspect the alc. damaging the old transport wheel.
