This is not exactly correct. There bearing in the HR 8000 was made of brass. Phil Lippincott told them not to do it and Howtek went ahead anyway. He considered this quite dangerous (to the scanner). When they acquired Aztek, they immediately swapped out this bearing with a stainless steel one, made a dozen or so additional changes and put the scanner out as a DPL 8000.

The Premier was re-designed and re-built from the group up. Almost all the boards were combined into a single master board, reducing connection errors. The stainless screw was mounted on ceramic bearings to make it run as smooth as possible.

I have never had any issue with dmax...
