Older 67 card readers and 65 card readers

[James Linder]

I’ve always replaced this resistor on the 97 card reader because so many of the 97’s seem to have card readers that barely pull the cards through and the will sometimes stop before making it all the way through.

I have a good question for you. There is a component on the 97 keyboard/display circuit board that will create an error message after a card is pulled through a restored card reader. (Let’s assume the printer works fine and is not an issue.) I know this is true because sometimes I must install a replacement keyboard/display circuit board to get rid of the error message when reading cards. This tells me the card reader components are all working fine as well as the components on the motherboard that impact card reading.

So, if I could figure out what component(s) on the keyboard/display circuit board have failed, I probably have at least 6 of these circuit boards that could be repaired and restored to service. Could I mail one of these to you for you to troubleshoot and return to me? Or could you at least point me to the components on this circuit board that must work properly to avoid card reader errors on the 97?

Thanks
