RE: Hp-41C card reader - dead
I fiddled around with the forks and the internal copper bits, the curvy one and the one close to the magnetic head.
I left a card in the system and closed it. I attached it to the calculator and the system sprung to life. I could not switch it off at all. The card would not move but the motor kept turning. I used a screw driver to try and get more pression on the card nothing. I pulled the card out and the reader stopped. All I get now is a MALFUNCTION error on the display. I used the abrasive card a few times, it doesn't change anything. I switched to PRGM mode and tried to save the routine, inserting the card shows RDY 01 OF 1 the card scrolls but the result is always MALFUNCTION The O-Rigs seem to be working as the card is pulled through I recall reading about this issue but will have to browse my bookmarks in order to find the reason of this. |
