HP-65 Card Reader Problem Help

[Geoff Quickfall]

Actually it is an eccentric cam, albeit very slight and it does adjust the height of the pinch roller. This does affect the read and write ability. I have adjusted units that write only and turned them into read only. Then adjusted back to the units sweet spot to have read/write working.

I will dig up the manufacturer of the tubing I use and post it.
