Agfa SelectSet 7000 not imaging

[damien@work]

We have a selectset 7000 that has stopped imaging but otherwise seems to be working as normal. It acts like it is imaging but when we process the film in the developer nothing shows up. I have replaced the board that goes the imaging head ( the flat cable) and I have also replaced the laser and laser supply. I am wondering if anyone has any other ideas of why it is not imaging?

Thanks
Damien
