Hi. I have an Epson Perfection 2400 scanner, but now I'd like to buy a
faster one.
I mainly use it to scan documents, pages from books etc.; I usually
scan at about 240 dpi, monochrome or grayscale.
What are the fastest scanners running on Linux?
(http://www.sane-project.org/sane-mfgs.html says which scanners are
supported by Linux and which are not)

I've googled for information about scanning speeds, but I found no
satisfactorily comparable data.

So, I have myself measured the speed of my scanner; I hope someone will
answer informing about scanning times for other (faster) scanners, so
that they can be clearly compared.

In each of my measurements, I started timing when my scanner (Epson
Perfection 2400) was making the first noise, and I stopped the timer
when the scanning was complete (that is, before the optical system
started moving back to its rest position).

When I scan the maximum scan area (21.59 x 29.72 cm² = 8.5 x 11.7
inch²) in grayscale, my scanning times are:
100 dpi: 8 sec
120 dpi: 10.5 sec
133, 144 dpi: 11 sec
150, 175, 180, 200, 216 dpi: 11.5 sec
240 dpi: 12 sec
266, 300 dpi: 15 sec
320 dpi: 27 sec
350, 360, 400 dpi: 28 sec
480 dpi: 36 sec

When I scan a square sized 15.02 x 15.02 cm² (= 5.92 x 5.92 inch²), on
the "nearer" side (the side of the optical system in its rest position,
I mean), in grayscale, my scanning times are:
100, 120 dpi: 5 sec
133, 144, 150, 160, 175, 180, 200, 216, 240 dpi: 7 sec
266, 300, dpi: 8.5 sec
320, 350, 360, 400, 480 dpi: 15.5 sec

Bye.
