Tony, Thanks for the details. If you ever do this again, how about a few digital images along the way :).
After I removed the lamp, I tried to remove the film carrier. With the scanner oriented in the same fashion as the background shot on the website you quote below, I removed the two sheet metal "caps" that retain the ends of the rails. I suspect the two other screws that you refer to are under the film carriage on the left side. I marked up the background of the SS4000 Problems page and put it here: http://www.tallgrassimages.com/gallery2/gallery2/main.php?g2_itemId=590 I should have powered up the device and moved the carriage to the right--or used the suggestion of gaining access to the worm gear and moving it while powered off. Did you have to do one of those two options? Thanks Stan ---- Tony Sleep <tonysl...@halftone.co.uk> wrote: > > It was me who wrote the report originally.
