Calibrator error

Hi, I'm new to the forum, but am in desperate need of some help. I thought I would ask some of you veterans to see what you guys thought. I have a noritsu 2701 mp1600 and I have been getting some strange lines lately. Attatched is the Gamma exposure. Any help will be greatly appreciated. Thanks! I thought that the lines were a result of a bad lamp. When I did the lamp calibration, I received error 9013-02 calibrator error. I don't really know what else to do to fix the problem. I guess I could try deleting and reinstalling the uniformity software but I don't actually think the uniformity is the problem.

Hmmm....well that's a new one for the MP1600. I haven't seen that particular pattern before, lines are wrong direction for uniformity and filter wheels usually show a different result, but nonetheless something to check. Almost appears to be some form of non-linearity in the drive for the paper advance stepper (pulse) motor.

Calibrator problems are hard to resolve as it comes with the MLVA head normally and  retro fitting is not a task to look forward to, or easily undertaken.

Could have something to do with the MLVA itself but I'm sure someone else here will perk up with a relevant comment and resolve.

I think this is not a problem to solve with the uniscan SW, bcause the line are not from up to down on your print.

Look all prints in that way?

I think, it's could be a problem of the dichroric filters movement or of the papermovent during the printing...

have a look there...

Do your uniformity prints look okay?

do regular production prints display this?

At first glance i would lean towards a problem with the paper transportation rather than a unifomity  or gamma issue.

I have had lots of calibrator errors and the like and they have never display a print like that. Ithe closest I have come has been due to transportation of the paper through the mlva...bad timing, motor shot etc

I am still having this problem and, yes, all prints come out like this. I have had a Noritsu tech come out and change four different circuit boards without solving the problem. Now, however, the images are extremely zoomed in. This is costing me a lot of time and money. Any help would be greatly appreciated.

Well, the noritsu tech tried almost everything excpet removing the exposure unit. After many weeks, the trouble turned out to be the filter wheel. Apparently some dust got in there and caused these strange things to happen. Good news is the machine is fixed. Bad news is with parts and labor it cost me much. Thanks for the help though guys.
