I have an Imacon Flextight Precision III scanner that has developed a problem that has me baffled. When the film holder is being ejected after scanning is complete the rear end of the holder gets stuck and will not fully eject until I lift up the front of holder which seems to free it from some obstruction that I cannot identify. While the holder is stuck there is a great deal of banging noise which I assume is my very expensive stepper motor complaining, which can't be good. I've taken the scanner apart and cleaned it, but can't see what the problem might be. BTW, the scans themselves are fine Any ideas anyone?
