[sane-devel] Problem scanning with Samsung scx-4100 on centos 4.2

[Yaar Hever]

Hi there,

I have the same problem with my Xerox WorkCentre PE16. This 
multifunction printer is the same as Samsung SCX-4216F and Lexmark X215 
MFP (see: 
http://www.macosxhints.com/article.php?story=20050912064001292), and 
WorkCentre PE16 is reported to work on Mac OS X with Samsung's driver.

I am using Ubuntu 5.10 (kernel 2.6.12). Samsung's driver package contain 
backends for: "MFP 560 Series", "MFP 750 Series", "SCX 4x20 Series", 
"SCX 4100 Series", "SCX 6x20 Series", "SCX 4x21 Series", "SCX 4x16 
Series" and "SCX 4200 Series". I have tried: 4x20, 4100, 4x16 and 4200 
-- and all of them cause segmentation fault with "scanimage -d" and 
complain about "mfpport.ko" and "mfpportprobe.ko" as mentioned by 
Prajjwal Devkota.
The package also contains a fancy GUI that's supposed to detect the 
scanner, and it doesn't detect anything, nor does "sane-find-scanner".

As I would really like to use my scanner, I'll be more than happy to 
give any information necessary and to report on any suggested solution 
to this problem.

>(http://lists.alioth.debian.org/pipermail/sane-devel/2005-May/013660.html), but the problem seems to be a bit different than mine.  I also had a look at (http://hathawaymix.org/Weblog/2005-07-15), and copied the files as recommended, but could not get the scanner detected by sane-find-scanner.  I tried installing the rpm (rebuilt from source) from (http://oskari.saarenmaa.fi/rpm/), but that gave the same problem: scanimage segfaulting.  I am still looking for a way to get the scanner working on my fileserver, and would like any help or pointers you may give to point me in the right direction.
