Outgassing on Glass??

I have a new Epson 3170 with an outgassing
film on the inside of the glass... it doesn't
appear to be affecting the scans or anything,
but it is bothering me. I have a couple days
left to return it so I am looking for some
recommendations on what to do. I suspect and
have been told that this is a common problem
and to just clean the glass, but there seems
to be no easy way to get into the scanner
to do as such.

Thanks,

Cindy

IIRC this is a repeated post ...
probably never read the answers.

Thanks for your help. I really appreciate it.
Technically it is not a repeated post. I originally
posted a similar post over on alt.comp.periphs.scanners
and then I found this groups and thought I might get more
answers from this group since it appears to have more
traffic. I did read the answers, which basically said
that this can be a common problem and to clean the glass.
Well, I can't really clean the glass without ripping the
scanner apart, so I posted again to try and get some
additional advise/help/recommendations... so sue me.

I really want to know if this outgassing affects the
quality of the scans. To my novice, untrained eye, I
can't see anything but I would like others opinions.

Thanks again for being oh so helpful.

Cindy,

yes it will degrade the scans having that fog in between. It is
common. It is a dilemma if it's hard to rip it apart. That's the fact.
Send it in or rip it apart. Dirty glasses, shitty windshields, foggy
camera lenses INSIDE it all depends on the glass, the multicoating,
how "open" the lenspackage is and how much pullution there is in the
air.

Let me tell you this; my very expensive Nikon lenses gets it INSIDE.
The viewfinder in my Leica M cameras gets it INSIDE and I have to rip
the Leica topcover off after a couple of years to clean it up. Yes. I
do it myself....your not alone with this problem. Leitz tried to
explained it once like it was the "glue" in the rangerfinder that was
the bastard. Well, it could be grease from the mecchanism evaporating
during hot days as well....it could be the glass as all glass
evaporate gasses. Look at the mirror in the Nikon film scanners -
THAT's really frustrating. It beginns to build up quite soon and it
depends on how much care you are willing to pay to keep it in a dust
clean storage and never leave the slide crack open. Smoke, fumes and
whatever will speed it up. If beeing a perfectionist this is hell.
There's always a limit for what will VISUALLY effect the result. But
any fogging WILL degrade performance. Drive your car at sunset and you
will find out how sloppy you are on cleaning windows. A strong
lightsource in the right angle and you're deep down there in that
depression again. Dust on a lens surface isn't that bad, but that
foggy residue is a killer to imagecontrast.

Find a repairmanual and some special tools or just go for it with what
you've got at hands....or send it in and find out what a sloppy
technician can create on the glass surface. It's a dilemma.
