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
 usb 0x04b8 0x0122
should be ok.

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.
