? Full schematics for HP 82104A card reader ?
Does anyone have the full schematics for the 82104A card reader? The middle vertical prong (of five) is not responding during a card passage. Thanks.

Thanks so much. When I tried it earlier today the PDF file wouldn't load but now it does. The problem was simply the second fork prong switch not activating. Reader now works.

Here's the Service Manual. Schematic is in Section IV.
