Epson V750 - dust under glass

[nathantw]

I just received an Epson V750 and it's pretty exciting considering I'll
finally be able to scan my slides and negatives (I owned a Umax 1220S
that didn't do much of anything in terms of slides and negatives).
However, after unpacking everything and looking at the glass that
there's two white specks under the glass. Does anyone know of any way I
can get the specks off without invalidating my warranty?

Thanks.

Try turning the scanner on the side and running a scan while tapping the
scanner with your hand. Maybe that will dislodge the specks.

That's an interesting idea, but since scanners aren't designed to work
sideways I'm not too sure about doing something like that since I'll
run the risk of messing up the alignment. However, under desperation
I'll probably end up trying. ;-)

If you just bought the scanner, it would probably better to exchange it
for a clean one. Or have Epson clean it if dirty glass on new units is
a common V700 problem. Why risk the warranty over Epson's
manufacturing mistake?

Where are these specks?? Are they in an area that will actually
interfere with scanning your slides and negatives? I would just put
whatever slide/film carrier in place and see if the specks would be
where your slides/negatives would be. If the specks don't interfere or
only affect one or two areas I'd live with it until the end of the
warranty period and then clean it. If they are really a problem, then
I'd return it and demand a " clean" unit. The other alternative would be
to give Epson a call and see what they say (and get an E-Mail stating
it). They may just tell you to go ahead and clean it.

I have a v700 and assume it's identical (for the most part) with the
v750. To open the unit you have to pry 4 plastic plugs out you the top
(not the lid)to access the 4 screws that hold the top in place. I pried
one out to check for the screws Used a small pocket knife) and can not
see a way to get them out without it being noticeable that it was done.

Hope this helps,
Dave

PS - I have a PDF exploded view of the v700/750 that I can E-Mail to you
if you send me an E-Mail address.

Thank you for your reply. The two specks are in areas that I can avoid
if I'm scanning slides, so I'll just live with it for now. If I had
bought the scanner locally I would bring it back and get a new one, but
since I mail ordered it I'm not really feeling like paying for shipping
because of a couple pieces of dust I can eliminate with Photoshop.

Thanks for the offer for the exploded view. I'd love to see that and
will send you my email address.

Patience and a set of jewellers screwdrivers from the dollar store would be
my first thought.

Just open the scanner case and remove the white specks with a canned
air blow.
Check the scanner bed for haze and other dirtness: many times, even
with a brand new scanner, there might be some haze on the glass.
Just remove it with an household spry.

translate: ammonia + distilled water. Nothing else. No soaps, etc. and
OBTW, ammonia is corrosive to electronic connections, so don't get any
there or on the mirrors.

Turn the scanner on it's side and scan a few times. Usually knocks the
dust right off. Otherwise, remove the top completely and clean.

If you use canned air, make sure there is nothing else in, as in oil
free, and hold it away from the surface. Better bet is an antistatic
brush availible from many photo gear shops.

In my experience a good (!) micro fiber cloth does wonders! I'm
definitely a proponent of "dry cleaning" (both sides).

I have to clean the underside of my flatbed glass at regular intervals
and I tried all sorts of "wet" solutions, from lens cleaner to
alcohol, etc but they all seem to leave a residue. Sometimes this
residue appears a few minutes after the cleaning was done. More than
once I would inspect the glass, it appears clean, but by the time I
put it all together the residue shows up again.

But ever since I started "dry cleaning" with a micro fiber cloth I've
never had any problems. Just my 2c for what it's worth...

Don,

If you don't mind please post your source for micro fiber cloth and the
sizes available.

Thanks,

You can find microfiber cloths in many places now. Hardware stores,
Wal-mart, etc. I found one at Walmart in the eyeglass area. 3M brand and
very cheap.

On optical glass surfaces like lenses you could look for optical grade
microfiber cloth (extremely smooth and soft surface) at you photo
dealer's place, or at an optician's outlet (I have several cloths from
Rodenstock).

Your scanner's glass platen is probably much simpler uncoated glass,
so you could use an 'intended for glass' (*very* fine structure and
soft) version from your supermarket. Don't use a generic household
version with visible loops.

These very fine surface structures will avoid grit of many origins to
lodge itself in the surface. To avoid dragging anything other than the
cloth over your glass, brush the glass surface with a soft brush and
then (after shaking it out) use the MF cloth.

You obviously should avoid cleaning in a dusty environment, although
the cloth will get rid of the film of polution that builds up over
time (if need be, after breathing water vapor on the glass). You just
want to avoid replacing it with dust specs from inside the scanner. I
run an ionizer prior to delicate cleaning operations.

I got mine in a photo store on a trip to Germany a couple of years
ago. The make is "HAMA" and someone else reported they were also
available in Ireland. So it's not only a German thing. I paid 5 Euro.

It comes with a handy plastic container and the cloth size is 15x15 cm
or 6x6". The cloth is gray in color and - for what it's worth - by far
the best I've ever used! Fortunately, I got two so when one is the
wash I can use the other.

Don.

P.S. I just noticed, the little leaflet points to www.hama.de so give
that a try (I'm offline as I write this).

The trouble is they're not all made equal. I've gone through many and
some of the so-called "microfiber" cloths were worse than using
whatever you have on. Sometimes a shirt sleeve seems to work better!

Thanks Doug, Don and Bart. What a team.
