Recently our Stingray 63 imagesetter started shifting images to one side of the film. When we output a CMYK separation 63cm wide the Cyan image will image at the centre of the film the Magenta will shift around 1.5inches off center & so on until the image is partially off the media width.
We cleaned the feeding rollers, lazy loop roller, checked belt tension, performed Spinner test.
Spinner test results are as follows:
99596, 99597, 99598 for min, average and max
In the Spinner Variance test the Var 0 & Var 1 change every time we repeat the test 1st test Var 0=62864 Var 1=136 2nd test Var 0=62694 Var 1=306 3rd test Var 0=61950 Var 1=1050 Var 2,3 & 4 are always 0. Is this variation in the results normal.
Has anyone experienced this problem, I really appreciate any help
