EPSON V700, anyone had to clean underside of glass

Am wondering, due to glass cleaning issues on my 4990, if anyone has had
similar smoky plumes on underside of the V700 glass, and process to remove
to top. The V700 is quite different in appearance to the 4990, which I
learnt to open (not with ease) to clean.

Before purchasing the V700, I want to know what I'm getting into (my 4990
needed to be cleaned from the onset).

The first unit was returned because the glass was filthy, and the
replacement wasn't much better. Cleaning was done in my presence under
warranty, but got it home to find the glass smeary (not visible until
connected and turned on).

Only detergent and water would remove the smears, before a final clean with
a glass cleaner and an antistatic spray.

Sorry I can't help with the V700 but yesterday when cleaning the glass
on my 4490 prior to profiling it the light caught just right and I
noticed a great deal of filming on the inside of the glass. Just
wondering how much of an ordeal it was to get the glass off? Any idea
if it is really glass or a polycarbonate? Thanks.
 
First, I have to apologise, my old Epson was the 4870 (not 4990). I sold
it some time back. I would imagine both have similar triple locking tongues
/ clips at the front. Because I sold my 4870 some time back, can't comment
on the glass or polycarbonate question.

Here is an old post from January 06...

The Epson 4870 can be cleaned, although removing the top is tedious
(releasing locking screw and then easing out 3 clips to the front). 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 a cloth in readiness to mop your forehead.

I found only detergent and water would remove the oily like film on the
glass's underside. In fact, every attempt to clean the glass with
conventional glass cleaner just resulted in smears. The final clean was
with standard window cleaner followed by Yamaha Extra High Gloss Furniture
Polish (polyester non-static Piano cleaner), and a buff with a soft cotton
cloth. Then came the torch test to see if any lint was present. A few
blasts from a can of compressed air will remove any lint. Finally reattach
lid, easing the front clips in then the locking mechanism.

The Yamaha cleaner is great for cleaning the whole unit, plastic and glass.
It actually repels lint and finger prints from the glass.

There is a file which contains an exploded diagram of the 4490 in the files
section of the Epson Scanners discussion group at Yahoo Groups. That may
help you figure out how to disassemble your scanner.

I have had the V700 since it came out in April. I was unaware of this
issue, my Expression 1600 died the week before the V700 was released.
Looking at the V700 right now I don't see any residue on either glass.
Scans still look very good. Will keep an eye out for this in the
future. Also the Area inside the V700 is larger than the 4990, may give
better air circulation. I have done 5-600 scans with this unit.

Not that I want to spoil that, but if in the future you want to check
for dirt build-up, shine a laser pointer through the glass at an angle
(careful for internal reflections getting back at you). That will show
any pollution / outgassing film building up over time.

Just went over it with a pen light, looks fine.

There is a plan break down for the 4870, 4990 and V700/50. The first two
are similarly designed, and both far from easy to open and clean (I
remember it so well... too well). The V700 series appears to have only four
screws holding the top down, and without other linked parts, lifts as one
piece for easy cleaning. I don't know how cleaning would affect the
antiglare treatment on the V750.

Only the V700 is listed on the Epson Australian website. Perhaps the V750
Pro wasn't imported.

There's only one Japanese model corresponding to the V700 and V750. My
understanding is that the hardware is the same, it's just the software and
accessories that are different.

I believe you are right. This will make for easier cleaning. The lock on
the side of the scanner and the front panel button wiring shouldn't be a
hassle like they were with the previous scanners. The caps that hide the
screws look like they still serve a dual function - hiding the screws and
indicating that someone has tried to get into the scanner ;) Can't blame
Epson for using these though.

A much better way to determine if the glass is dirty (on either side!)
is to scan "nothing".

Open the lid, don't put anything on the glass, and darken the room
(best done at night).

Scan. As the light passes under the empty glass look at it at a very
shallow angle. Actually, I get down so my eyes are parallel with the
glass. It's amazing what can be seen like that.

Take the resulting scan - which at first blush looks totally black -
and import this image into the editor of your choice and then brighten
up the image. It's best to use curves so you don't clip.

After a few times (repeatedly boosting curves) the image will turn
gray. At this point examine it at 1:1 magnification and you'll see
every glass imperfection and any spots, scratches, debris or streaks
on either side of the glass.

It's quite an eye opener!

For compulsive scanner glass cleaners like me it's truly a horror to
look at! ;o)
