HP41CV cardreader
Message #1 Posted by Karel Marchena on 14 Oct 2003, 9:01 a.m.

I repaired the cardreader with fuel line and it runs o.k. but gives a card error massage each time after reading the magnetic card. I resized the register to 026 so this is o.k. too, but still gives the error massage. I realised that I switched the black electrical wire with the orange wire. Maybe I damaged the cardreader doing so?. After having this problem I switched it back. The cardreader still gives the error masage. Maybe I need to buy a new cardreader? Is there anyone who has a cardreader?Please advise. Thanks Karel

Switching the head wires should not damage the reader. Make sure that the black and red motor wires are routed as far from the head as possible.
