Usable scan area

I am curious what is the typical usable area of a flatbed scanner. I can see
the scanner bulb extends beyond 8 1/2 inches and the travel of the bulb is
longer than
11 inches, yet I have yet to figure out how to scan full 8 1/2 by 11 inch
documents,
or even larger sizes that fit onto the flatbed.

Also, I would like someone to define some of these terms in my manual like, A4,
A5, LTR, LTR/L, and LEGAL. They also appear on the sides of my flatbed table,
but make no sense when used with Epson's Smart Panel Program.

Generally the 1-2mm (less than 0.1") abutting the plastic frame does not
scan, regardless of where the lamp goes.
A4 and LEGAL etc. are important terms to your printer, not so much to the
scanner. The rest of the world uses the International Standards
Organization [ISO] dimensions for its A/B/C series papers based on the
ratio (sqrt1/1) but if you never leave the U.S. you never see them;
OfficeDepot doesn't stock any of the paper, altho' they have ring binders
for them. LTR is 8.5x11". LEGAL is 8.5x14", fading in popularity 'tho
OfficeDepot still stocks. If the scanner bed is less than 12" you cannot
get a 100% scan of legal-length paper.
You have no options in source or target size until you choose
'Professional' in the MODE field at the top right of the Smart Panel
window. In Preview View you move the crop borders, on your printer you
change your forms in its software and change the paper in the feed tray.

I'd imagine the light goes past the scan area so the light doesn't fall off
and leave a dark edge.

The professional mode lets you set the scanner area, but I cannot get it to
scan outside of a fixed area, somewhat less than 8 1/2 by 11 inches. You can

crop the borders in Preview Mode, but they only allow you to reduce down
from the limited area taken in by the original scan, which is 8.29 inches by
10.77 inches.

The ISO uses square root of 2 (=1.4142) aspect ratio for the A-series sheet
size. A4 (the closest size to our LTR) is 210x297 mm. You get A5 by folding
A4 in half, resulting in 149x210. A3 is twice as big as A4 or 420x297, and
so on, up to A0. You get the idea...

A4 is a size in the range of the European A-series papers, which run
from A0 to A6. The dimensions are in the ratio of 1:sqrt(2) for all
sizes, and that ratio allows successive halving of any size to produce
two sheets with the same aspect ratio, i.e. cutting with no loss. An A4
halved produces two A5 sheets.

A4 is the most commonly used size outside of the USA, at 210 x 297 mm,
or 8.25 x 11.7 inches, slightly narrower and longer than the American
Letter, which is 8.5 x 11 inches.

Most recent scanners will scan an 8.5 x 11.7 area, which covers both A4
and Letter sizes. What scanner are you using?

Hi Colin,

I'm using the scanner from an Epson RX500, All-In-One. I have tried everything
thinkable and I cannot capture an image larger than say about 8 X 10 inches. Trying
to copy standard letters and documents that have information close to the edge of
the paper have the outer information cut off. I can see the scanner bed is at least
as
wide as a LTR size and the scanner light extends beyond the width of the document
and travels well beyond its length. I'm using Epson's Smart Panel Software and the
Professional Mode direct Epson Scan and none of these options will capture a
complete standard letter size.

It looks like you have a problem there, perusing the web didn't reveal
anything concrete, and I noticed you had done the same. How about
returning it to your supplier quoting the Sale of Goods Act (or similar
in your country) and saying it doesn't do what it is purported to do,
and request a refund? The law here in NZ says that if an item doesn't
do what is claimed, and will not do what you bought it for, namely scan
Letter or A4 pages, then you are entitled to return it regardless of any
guarantee limitations.
