RE: Hp-41C card reader - dead

Hi Tony, I have read the pdf a couple of times. I have turned the drive pin 360 degrees, a bit at the time, to see if it was a card dragging pressure issue and nothing changed. The drive roller on the drive pin spun freely without any sort of friction before attaching the motor.
I'll try taking it all apart again and see what I have missed ?
Thank you
Marco
