RE: Hp-41C card reader - dead
My understanding is that the cam has to be rotated until the tension on the card is just right. IIRC there is a little bit of an offset. I've used a jewelers screwdriver on the slot of the drive shaft - 1/8" turn - test.
This is off my memory of reading one of the repair posts here (or archived). Hopefully I remembered it right, correct me if I am wrong please. Bill |
