I have a Dolev 800v that we recently moved to a new location. Shortly after the move, the stepper motor quit operating and I put in a used motor. Initially it had some scan line dropouts but eventually seemed to settle in and image solid. But the images are now bowed--they dip down in the middle and the image is not square to the cut of the film. If I print a grid and fold it in half the lines are off by 1/32. I thought the replacement stepper motor might be out of spec so I bought a new motor exactly like the original. The issue improved but did not go away. I find it hard to believe that the problem is related to the stepper motor but I am out of ideas. I did mess with some diagnostics while resetting the home position during the process, so don't rule out the I accidentally reset something. I have checked the NVM table and they appear to be set to factory settings (not default settings).
Any ideas.
