[filmscanners] RE: SprintScan 4000 cleaning

["Cliff Ober" <cdober@ev1.net>]

John,

I started noticing dark areas from many high contrast slide scans were
exhibiting a bit of flare or fog. It really was noticeable near an
abrupt transition from light to dark. I've had the scanner for three
years now, and I was pretty sure it would be pretty cruddy, based on
comments here from some other folks.

As far as posting the steps, there's far too much involved in the
process to describe, especially with text only. It really would require
a several page manual with a number of photos to do it right. I'm
willing to answer specific questions, but I just haven't the time to
create a service manual. Of course, if Polaroid is interested in
contracting out some work...    :^)

Cliff

Two questions:

What's the best way to determine if your mirror needs to be cleaned?

- and -

Any way you could post the steps you went through to get to the mirror,
clean it, etc. so that others that own this nice scanner won't have as
much of a learning curve as you had to go through?

Obviously I have one myself, and, at times, I've noticed some things in
the scans that made think it needs some maintenance while other times it
seems to still do an excellent job after ~2.5 years of use.

Thanks -
