scanner?

Hi All,

W7-pro-x64

I have a customer that needs a stand alone, flat bed
scanner that will do 8-1/2" by 14".

Any favorites?

Many thanks,

EPSON WorkForce DS-1630 (B11B239201)

It's CIS, which means no depth-of-field. If you take a
textbook and lay it on the bed, none of the text near
the binding will be visible. A CCD sensor will pick up
that text on the curve, as it has depth of field. Most
scanners were CCD, many many years ago. Now, they're
all CIS, with few exceptions.

Document scanning only needs 150-300DPI, as you only
need enough resolution to meet Nyquist on media which
is printed with dots (half-tone). You count the dots,
to figure out the correct scan DPI. A "de-screen" plugin
does the best job of anti-aliasing the resulting image.
So while 600DPI optical resolution may seem restrictive,
in practice it's good enough.

For photographic paper or negatives, you can find a
smaller scanner with 6400DPI, dual illumination for
dust and scratch removal, 2 minute per page scan time,
an entirely different beast. The grain size of photographic
paper or negatives, means you can crank the res all you
want.

If you expect to be doing mostly office work, then you're stuck
with the low-res unit, because the scan times will almost
be reasonable. I own a scanner with a 2 minute scan time,
and I can tell you, it's a real damper when it comes to
scanning. Waiting and waiting... You want a scanner which
only takes a few seconds per page.

You will likely have to visit a lot of web stores, to
get a good picture of what is available.

Before you race off and do a victory lap, a
word of warning.

https://epson.com/For-Work/Scanners/...r/p/B11B239201

scan up to 8.5x11 on the platen
scan up to 8.5x14 on the ADF

If your ADF breaks, then laying the documents flat on the
platen doesn't give you a 8.5x14 scanner. The duplexing
storage area defines the 14" limit. One other scanner
with an ADF (but no duplexing function), describes their
scanner as 8.5xN, as it'll just keep grabbing an infinitely
long sheet and shove it into the output tray area.

*******

This is another Epson, probably the model replaced by the DS-1630.
It's price should be the same as the DS-1630.

https://www.newegg.com/Product/Produ...9SIA61K53X2908

I have a lot of trouble, judging by eye, whether I'm getting
an 8.5x14 platen there. It might be another 8.5x11 platen.

*******

This one is pretty expensive (and maybe the price is wrong),
but this one right on the web page, says both the ADF and
platen scan 8.5"x14".

HP Scanjet 8270 $598 ???
https://www.newegg.com/Product/Produ...9SIA6AU4UH5273

It has a duplex ADF so flips the paper for the second scan.
And then the paper has to be in mint condition, or the
duplex request will jam up. Maybe it runs a bit better
in simplex mode.

*******

And then the price shoots up from there. This one has an 8.5x14 platen.

The prices are all over the place on this stuff.
It's like a used car lot, where the price changes
depending on whether you're wearing a skirt.

If her printer is getting long in the tooth, it might be a better buy to
get an all-in-one now instead of replacing the printer later.
Stand-alone scanner + printer is considerably more expensive than
all-in-one. The only difference between copy and scan is software; and
adding a copy/scan engine to a printer is cheap compared to building it
into its own box.


She has a special stand alone printer for printing legal forms.

(You should have said what the purpose was, though [a] the size you
mention suggests it's documents rather than photographs, [b] you have
confirmed that later.)

I have a small scanner that is like that: it's a feedthrough scanner (no
duplex), that is about standard width (A4 for Europe, 8.5" I think is
what you use in USA), but unlimited length - as Paul says, it just keeps
feeding through indefinitely. I find it handy as it's very portable -
goes in a tubular bag. The good length capability is useful for
genealogy (birth/marriage/death certificates in the UK used to be rather
long, or rather wide).

IIRR it's an Antec. I won't recommend it for you, as I suspect you want
(though not necessarily high-resolution, as someone else has said),
_accurate_ scans, and this does tend to skew a bit if you're not careful
as you feed them through.
