Running the Epson Perfection 3490 Photo scanner with sane
The Epson Perfection 3490 Photo scanner (product web site) is supported by sane, using
the snapscan backend.
Installation is straight
forward, it is simple, provided that sane is installed,
it is a Linux-only solution, but the following:
may occur: Error
[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:
/cdrom/ESCAN/ModUsd.cab (this is an M$ Cabinet
archive).
Extract it with cabextract, move it to the appropriate
directory, e.g.
$ mkdir
/usr/local/share/sane/snapscan/
$ mv Esfw52.bin
/usr/local/share/sane/snapscan/
In the config file /etc/sane.d/snapscan.conf
just add the line
firmware /usr/local/share/sane/snapscan/Esfw52.bin
near the top.
The firmware line
# Epson Perfection 3490
should be ok.
usb 0x04b8 0x0122
If you are in the group scanner (and maybe
saned) you can
start 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.
