I apologize if this is a second message to the list, I think the first one didn't go through
 
We are having a bizzare scanning problem. Straight vertical lines in an object become slightly zigzagged with a period of up to 6-7 scan lines, and there also may be some oscillation in the intensity. The period and the magnitude of this periodic noise depends on the scan speed and the scan size. So far we (with the help of an Olympus engineer) have established that:
 
1. It doesn't seem to be the scanner controller or the galvo mechanism
2. It does not seem to be the electric power in the building
3. It is not a mechanical vibration
4. It is not a computer
5. It is not the cables
6. It is not a 60 Hz noise
 
Sometimes connecting the scanner controller to the outlet through a long extension cord seemed to help which may suggest a problem with grounding, but as soon as we concluded that, the trick stopped working. The trouble could not be reproduced at the Olympus testing lab.
 
Has anyone experienced anything similar and successfully resolved the problem?
 
Many thanks in advance!
