Samsung SCX-4521F on LMDE 64bit: Printer ok, Scanner nok

[yaq1]

Hi *,

I followed these instructions:

and the Printer works fine.

samsungmfp-scanner in version 3.00.90-2 is installed, but xsane doesn't find a scanner (neither as root). On switching on the printer, /var/log/messages says:

Code: Select all

My user is in the "lp" and "scanner" group.

I also tried:

Code: Select all

$ sane-find-scanner

  # sane-find-scanner will now attempt to detect your scanner. If the
  # result is different from what you expected, first make sure your
  # scanner is powered up and properly connected to your computer.

  # No SCSI scanners found. If you expected something different, make sure that
  # you have loaded a kernel SCSI driver for your SCSI adapter.

found USB scanner (vendor=0x04e8 [Samsung], product=0x3419 [SCX-4x21 Series]) at libusb:003:006
  # Your USB scanner was (probably) detected. It may or may not be supported by
  # SANE. Try scanimage -L and read the backend's manpage.

  # Not checking for parallel port scanners.

  # Most Scanners connected to the parallel port or other proprietary ports
  # can't be detected by this program.

  # You may want to run this program as root to find all devices. Once you
  # found the scanner devices, be sure to adjust access permissions as
  # necessary.
$ 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).

ok, there it says what I should do next.... anyway, before I go hunting the straw in MBs of manpages, any suggestions?

[yaq1]

ok, by now I tried the manpages & stuff. Not really helpful (for me...).

I'm stuck ...

"anyone? anyone? class? anyone? anyone know what this is?" ;o)

oh, one more thing, that might [not] help: I did use the same hardware & samsung-package before under Ubuntu where it did work fine
(yes, YAUR - yet another unity refugee...)

[yaq1]

come on, guys, don't leave me hanging on like this - anyone got a clue where to look or what to do? Any suggestions where else I could ask for help?

I have the same problem with the 32bit edition.

modprobe usblp

makes the scanner available, but then the printer is no longer working.

I found a more complex solution here:

which used to work with Ubuntu and Debian, but is not working with Mint.
