Hi Dan,
I am replying off list because I don't think my comparisons of the 3600 and
the ss4000 is scientific by any means. I returned the 3600 for two reasons.
The first is that it sounded like something was grinding inside the unit
whenever it was in use. This may have been the reason I was
I had one. I sent it back for the SS4000. I may have had a bad unit, but
it crashed my Mac G3 every third time I tried to acquire the scanner's
software from within Photoshop. It seems to be memory hungry. My unit
sounded like a jack hammer when it scanned. It could have had an
internal problem.
Could it be dust in the scanner?
