Epson Perfection Question

I recently purchased an Epson Perfection 3170. Had used for about 2 weeks
and noticed some dust on the Platen glass. While cleaning the glass with a
soft cloth the scanning lamp was on and I noticed a faint greasy looking
film on the underside of the platen glass. As far as I can tell the scans
produced are excellent (reflective scans only to this point). Is this slight
oily looking film normal or a manufacturing defect? Any way I can "push the
limits" of the scanner to see if this is subtley effecting scan quality? If
I need to is there any way to relatively easily remove the glass to clean
the underside? I purchased the scanner Amazon since no local vendors carried
it and returning it would be not worth the hassle.
Thanks in Advance

Epson flatbed scanners seem to vary in terms of dust or films on the
underside of the glass. Mine has a slight film in the calibration area
which is only visible from the side and is very hard to see.

It is possible to open the scanner and clean the glass. I don't have a
reference handy, but a google search ought to locate one or two websites
with complete instructions. As best I can tell, all the Epson scanners
are put together in similar fashions, but there may be some variation
among models. However, it is going to be very hard to clean the
underside and reassemble the scanner without introducing more crud than
you eliminate. So if your results satisfy you, don't worry about it.

The files section of the Epson 2450/3200 or 4870 Users Groups at Yahoo
Groups has instructions that might give you a starting point.

I also experienced the haze on inside of the glass scanner bed.
(from out-gasing in the interior of the Epson perfection scanner )

Epson tech help said this problem is not user repairable - the scanner needs to be sent
in for repairs to correct the problem

Do not open up the scanner - there are no credible directions through Google to correct
the problem
 
The Epson 4870 can be cleaned, though removing the top is tedious
(releasing locking screw and then easing out 3 clips to the front). My
first unit; the glass was so dirty and smeared I sent it back. The second
had a smoky like haze on the underside. Only detergent and water would
remove this oily like film (bit like smoke damage or car exhaust). In fact,
every attempt to clean the glass with conventional glass cleaner just
resulted in smears. The final clean was with standard window cleaner and
good buff with a soft cotton cloth. Then came the torch test to see if any
lint was present. Luckily after a few buffs and a blow with compressed air,
the lid could be reattached.

Be careful with the front right hand side clip, as it's the one that
sticks. Sitting the scanner back on its end can help to release this. You
may need a friend to assist with cloth in readiness to mop your forehead.

After about 3 months a small amount of haze has returned, which I am yet to
clean. I clean the glass top and plastic surrounds with Yamaha piano
cleaner, as its static free (might be good for final clean and buff on
underside as well).
