Title: SCX-4521F and Raspberry Pi: suggestions?
Post by: Lx on January 07, 2015, 05:22:21
My goal is to make my USB-only Samsung SCX-4521F accessible over the network for printing and scanning purposes.

To avoid having to keep a power-hungry PC on, I've decided to set up a 512MB Raspberry Pi with the latest known soft-float ("armel") Debian distribution (Wheezy, found here (http://ftp://ftp.mirrorservice.org/sites/downloads.raspberrypi.org/images/debian/7/2013-05-29-wheezy-armel/)).  I figure that if I can get printing and scanning working locally from the Pi, I can worry about the networking element later.

On the Raspberry Pi I have the following driver options:

Code: [Select]
suld-driver2-1.00.06 - Samsung Unified Linux Driver2
suld-driver2-1.00.21 - Samsung Unified Linux Driver2
suld-driver2-1.00.27 - Samsung Unified Linux Driver2
suld-driver2-1.00.29 - Samsung Unified Linux Driver2

and I've tried them all (explicitly restarting saned each time I've changed the driver).  With drivers 1.00.27 and 1.00.29 I can't see the scanner at all:

Code: [Select]
# scanimage -L

No scanners were identified. If you were expecting something different,
check that the scanner is plugged in, turned on and detected by the
sane-find-scanner tool (if appropriate). Please read the documentation
which came with this software (README, FAQ, manpages).

With drivers 1.00.06 and 1.00.21 I can see the scanner:

Code: [Select]
# scanimage -L
device `smfp:usb;04E8;3419;8P54BAIQ223032B.' is a SAMSUNG SCX-4x21 Series on USB Scanner

and when I try to scan, some physical activity happens within the scanner, but the operation fails within a second or so:

Code: [Select]
# time scanimage --device-name='smfp:usb;04e8;3419;8P54BAIQ223032B.' > out.pnm
scanimage: sane_start: Error during device I/O

real    0m1.012s
user    0m0.090s
sys     0m0.010s

Frustratingly, I did manage to scan some individual pages earlier; I don't believe I've changed any other aspect of the system's configuration though.

My questions for anyone willing to suggest answers are as follows:

After much frustration and little hope of advancement towards a solution, I gave up and resorted to connecting the unit to a full-scale PC via USB.
