HP67 card reader problems Message #1 Posted by JohnC on 1 Dec 1999, 12:08 a.m. This is probably a common question, but what can I do to fix my HP67 card reader? It appears to be gummed up with who knows what - not sure if it is lubricant which has flowed or if the rubber wheels have turned to jelly. Cards will not pass through. Is there any hope?

I have made the repair on a 41 card reader, but never a 67. I have heard there are many more small parts in the 67 so be careful. Randy

The reader mechanism is pretty much the same, but I found that they're somewhat easier to disassemble/reassemble. The small parts (like the small vynil roller and balls) need to be watched in any case. One of the quickest ways to kill a vintage calculator is to try and disassemble it, for instance, in a room with a carpeted floor! Viktor
