The printing in multifunction Samsung SCX-4200 is correctly recognized but Xsane doesn't recognize the device. Please add "usb 0x04e8 0x341b" into /etc/sane.d/xerox_mfp.conf

Binary package hint: libsane

1) edubuntu version 9.10
2) xsane version 0.996-2 ubuntu1
3) recognition of the scanner
4)Answer of Xsane "non è disponibile nessun dispositivo"

I found, thay Samsung SCX-4200 scanner works fine with the xerox mfp driver (look at http://lists.alioth.debian.org/pipermail/sane-devel/2009-June/025028.html ).
Please add USB ID of SCX-4200 into /etc/sane.d/xerox_mfp.conf - this is just one line:

echo "usb 0x04e8 0x341b" >> /etc/sane.d/xerox_mfp.conf

I can confirm, that this works fine with my Samsung SCX-4200 (I've started xsane from root user, because scanner device file has wrong permissions, it seems udev rules should be tweaked...)

Assigning to correct package - file /etc/sane.d/xerox_mfp.conf from sane-backends source package should be patched to support scanner from Samsung SCX-4200 Multifunction device.

Gelam, Thanks!!!!!

Just did the same for my Samsung SCX-4623F and now works perfectly. In my case it was:
echo "usb 0x04e8 0x3434" >> /etc/sane.d/xerox_mfp.conf

For everyone else with a Samsung multifunction/scanner, you can get the appropriate vendor ID and product ID with "sane-find-scanner":
$> sane-find-scanner
found USB scanner (vendor=0x04e8 [Samsung], product=0x3434 [SCX-4623 Series]) at libusb:001:010

In my case sane-find-scanner was always reporting the proper scanner found, but then it was not listed by scanimage -L. Also, scanimage -d xerox_mfp:libusb:001:010 was failing with "Invalid argument" (not after adding the line to xerox_mfp.conf)

After adding my scanner conf line to use the xerox_mfp backend as above, scanning works perfectly with the Simple Scanner in Lucid.

I confirm this solution to be valid for Samsung SCX multifunction sets. Thank you!

Inspecting the source tells me this should be fixed in quantal and raring. Can you please confirm?

[Rolf Leggewie (r0lf)]

and it seems to be in precise as well.

$ grep 341 /etc/sane.d/xerox_mfp.conf
usb 0x04e8 0x341b
usb 0x04e8 0x341f
