Vertical lines as it is visible on normally exp shots, but not so it is appreciable.

In what there can be a reason?

It looks like you need to replace the tension belts - they are toothed to give incremental movement of the film in front of the sensor and these teeth are probably not the right size anymore -- they are a maintenance item that needs to be replaced. When this happens the film moves jerkily in front of the sensor and you get banding perpendicular to the film path (like your film).

That's my first thought.

Jeremy is right. I'd be surprised if this doesn't solve the problem. I've done this service and it needs about an hour of technician time. I seem to recall that Imacon/Hasselblad supplied a kit with the belts, at least one gear and various bearings. I'd check with them.

There is a Yahoo Imacon scanner group. If you search back through the message archives there is information on where/what to buy and how to replace them yourself if you are so inclined.
