EFI Vutek printer giving intermittent DOOR OPEN errors

We are getting periodic DOOR OPEN errors from our Vutek printer. Doors are all closed, electrician has verified that the correct voltage is reaching the power board from the door sensors. Power board in the printer was replaced with a new one last week. Printed a weeks worth of orders this morning beautifully but then just randomly popped up with the DOOR OPEN error message this afternoon. On the job immediately prior to this one it did give a LED LAMP ERROR message so we shut down and restarted and it appeared to be working fine but halfway through the next job we got the DOOR OPEN message. Anyone have any ideas before we have to get a tech in to throw parts at it?

It sound like a tired door switch, Have you just tried putting a paper spacer over the switch? I have seen this on several types of machines.

You can unscrew the sensors and tape them together with some gaffers tape. The sensors aren't seating correctly and the vibrations while running periodically are knocking them out.

We have bypassed all the sensors, they aren't the problem. Problem is that the power board is okay sending out two volts to the sensors instead of 12. When the power makes the loop and comes back the low voltage reads as a sensor being open. I was hoping someone knew why the voltage was wrong.
