Hp HP LaserJet 4

HP4 card reader

We have an HP Laserjet 4 that has a magnetic card reader that was used to make students pay for their print jobs ahead of time. The card reader was installed by splicing some of the wires inside the machine and running it through the wiring of the card reader. We now want to redeploy this printer in a non-pay setting. How can I undo this splice and enable normal printing once again?
It would be almost impossible to advise you on this one. Without seeing the installation, there's no way one could tell you how to undo it. Can you at least pop off the right side panel and see where the wires go into the printer? Might give some clue how to do it. If you have a digital camera, you can email me a photo of it.
