System 89 white edges problem

Hi. We experienced a problem with leading white edges on prints. Kodak suggested cleaning exposure plane sensors which we did. Problem fixed - now we have TRAILING white edges!!! Checked paper feed and exposure plane position settings - all ok, but images are well to right of paper centre. We printed patterns for alignment settings (frightening!) but have no green corners on right (leading) edges! Fear it may be lens position settings (more frightening still!). Does this mean anything to anyone or do I need an expensive callout cos I'm fed up with trimming 1-2mm off my prints!

In SuperUser there is an adjustment for paper positioning.  This prints out a test print that you use to make adjustment.  You will have to look in the manual for the details, as have not done it for ages.

Does the lab use a mirror to direct the light onto the exposure deck as the older System 88?

Thanks Nick. I've done both the paper feed and exposure plane paper position adjustments in S.U. But when I try the alignment test pattern prints the print should have 4 green corners (only 2!), if not, the help file suggests other scary routines such as zoom lens position tests first!

No mirror in 89 I don't think. Don't know whether to plough on with the alignment measurements (about 15 micrometer measurements!) or not. Course I could just give K another bag of coins!! Thanks for suggestions.

Thanks Steven, the paper adjustment is for top & bottom edges, but doesn't seem to have leading/trailing settings. Have now run lens/lcd position adjustment, now spot-on, but no effect on paper position. Going to run the alignment tests, lots of micrometer measuring! See if that sorts it.

Sorted! You'll be glad to know (well I am!) that the alignment prints in SU 'Centreing' have done the trick but it takes forever with 15 micrometer measurements per test (needed 3 test runs), so leave lots of time. Conclusion - the alignment tests correct for longterm drift of various lens, lcd & paper transport systems. At last no more print trimming!!

Thanks for suggestions - if anyone else with an 89 (or KIS equivalent (DKS1550?)) has similar problems I'll be glad to help.
