Monophoto keyboard question

[John Nixon]

Hi all,
We have an electronic keyboard for the Monophoto.
The punch continually reports a "tight tape" error.
Does anyone have experience or information regarding this issue.
Cheers, John

John, did you find a cause for this error message? If not, I would suggest looking at any micro-switches or sensors that the paper runs over, the paper may just be out of position, not really tight. Also, look at any relays that sensors connect to, they all have a 'best before date'. And if you are into the electronics, capacitors also have a shorter life. Hopefully, if you get into the electronics, you have the schematics.
