      Go to service check. Then run self diagnostic. See test results.

        Results: the rest is good except this : AOM SETUP VALUE- NO GOOD
        What next now?

      Check all your AOM drivers are good.

        Thank you Mr Noritsu and Minilab for your replies..
        Have replaced all 3 AOMs with new ones. And now we are getting this (see attachment). Which boards should I check as well- (would prefer board or part numbers).
        Thank you.
        Regards

          If on test you see that AOM setup value not good and no changes after all AOM drivers replacement then probably laser control pcb will be faulty.

            Hello guys.

            Phew! Last week I cleaned the exposure unit and dark images started coming out when trying to print photos. I just switched off the machine and left it for days whilst I was looking for the laser PCB. I switched it on , ran daily setup without changing anything and its up and working well. God knows what happened. Now am thinking there is a hidden fault somewhere in the boards or laser unit which is giving intermittent faults. Will update you if I finally get to the cause.
            Thank you all for your help.
