Running the Epson Perfection 3490 Photo scanner with sane
The Epson Perfection 3490 Photo scanner (product web site) is supported by sane, using
Installation is straight forward, it is simple, provided that
sane is installed,
it is a Linux-only solution, but:
One step took me some extra minutes, as running
threw the following
[snapscan] Cannot open firmware file /usr/share/sane/snapscan/your-firmwarefile.bin.
[snapscan] Edit the firmware file entry in snapscan.conf.
The firmware is on the driver installation CD that comes with the
scanner it is located the file - that's what had to be guessed, at
least I didn't find it in any documentation:
(this is an M$ Cabinet archive).
Extract it with
cabextract, move it to the appropriate
/usr/local/share/sane/snapscan/Esfw52.bin And edit the
$ mv Esfw52.bin /usr/local/share/sane/snapscan/Esfw52.bin
firmware line in
If you are in the group
scanner and eventuelly
saned (I frequently forget to edit
/etc/group when setting up sane
;-)) you can
xsane and scan.
It is possible to run the scanner without the firmware file being located on the Linux file system, if it has been used with the proprietary driver (under a proprietary OS) before, but this is not a persistent solution as the scanner obviously forgets its firmware during a power cycle.
And by the way: CinePaint (formerly FilmGimp) seems to be a good
alternative to The Gimp for editing images with 16 bit per
channel colour depth. - And thanks Douglas for also pointing out nip2, "a spreadsheet-like
graphical image manipulation tool."
