Thanks Again.
I'm off to the SANE website to see if I can work out how to work with it.

This is by way of thanks for sticking with this non-expert: Simple Scan now works & 'Xsane image scanning program' produces a preview and whirrs happily when told to Scan; though I have yet to find where it dumps the result.

A couple of notes to any other reader with low expertise:
As explained in the thread: to uninstall "samsung  Samsung  smfp-common" I had to do the totally counter-intuitive & Download the Samsung INSTALLER v1.00.36 from this [bchemnet] site before I could uninstall.

When I ran  "~$ sudo apt-get update"           60+ files were updated but the final lines read:
"Reading package lists... Done
W: Duplicate sources.list entry http://www.bchemnet.com/suldr/ debian/extra i386 Packages (/var/lib/apt/lists/www.bchemnet.com_suldr_dists_debian_extra_binary-i386_Packages)
W: You may want to run apt-get update to correct these problems"

This may be because of the bollx I made of my 1st attempt. I did run apt-get update again but the warning remained so I ignored it & that seems not to have interfered with the ability to Simple Scan.

Many thanks again.

Thanks.
As advised I use Synaptic to 'completely remove' :
suld-driver – 4.00.39
suld-driver- common-1
suld-network-2
suld-ppd-1
suld-keyring

I run ~$ ls /opt/   OUTPUT=  samsung  Samsung  smfp-common
So I need to Uninstall  version 1.00.xx
The Samsung Installer tab seems not to offer a Terminal command for uninstall, it just says "To execute the uninstaller, execute (as root/sudo, and in a terminal) the uninstall.sh script in the installer download or in /opt/".
Since [in Nautilus] I have no Installer download file that I can find - or ANY directory or file named 'samsung Samsung' I use a manual search for the listed files  in Synaptic.
It finds NONE of those listed, or any hits on 'smpf'.
How come Terminal says  'samsung Samsung' exists but Nautilus & Synaptic can't find it?
Please provide instructions from here. Happy to work with Terminal, but [as you'll have seen!] my expertise is about 11% so specific command lines needed please. Thanks.

Many thanks - it worked.

A/ An apology is due. I must have installed something from the Samsung site .... I thought I'd lost my scanner disasters log but I now find the following notes to myself:
"I downloaded from http://www.samsungsetup.com/TS/Files/RDS_XML/web_install_agent/linux/SamsungPrinterInstaller.tar.gz
Various failures followed eg: "./noarch/package_install.sh: 46: ./noarch/package_install.sh: ./noarch/package_install.sh: Permission denied"

Eventually I got xsane installed and available through Applications>Graphics. Only trouble was, trying to scan preview using screen 'Preview Samsung SCX-4100 Series on USB:usb;04e8;3413;0123456789ABCDEF' I got a dialogue saying "failed to start scanner Error during device I/O" the saga went on .....

If I NOW search Synaptic on 'noar' I get no hits
If I search Synaptic on '46' I get nothing that looks like a Samsung hit, but [irrelevant?] I do get INSTALLED brother-lpr-drivers** & brother-cups-wrapper**

B/ In the interim your 'cd' instructiom worked well & I chose uld-driver-4.00.39 package.
I have downloaded and installed 5 'suld-***'  files from suldr-keyring_2_all.

However the output of '$ sane-find-scanner' gives 24 lines, 16 of which is "  # No USB scanners found. If you expected something different, make sure that you have loaded a kernel driver for your USB host controller ... "
the output of '$ sudo sane-find-scanner' is better: it says "found USB scanner (vendor=0x0ace [ZyDAS], product=0x1215 [USB2.0 WLAN]) at libusb:002:005"  but it still will not scan.

IF I should have purged all the Samsung driver stuff mentioned at A/ above then B/ was probably a mistake [sorry again]. Do I have to uninstall the uld-driver-4.00.39 package? If so please give instructions [I heard Synaptic can be iffy on uninstalls].

Sorry to be verbose: it may well be you tell me just to uninstall Version 1.00.xx if I can find out how.

Thanks:
To be clear I'm trying to get the SCX-4100 to scan under Ubuntu 14.04
Your "Samsung Installer" tab says:
"If you want to know specific details of what files are installed or how to uninstall particular versions of the driver installed the Samsung way, see the page specific for the version that you downloaded and installed:
    Version 2.00.xx (very old)
    Version 3.00.xx
    Version 4.00.xx
    Version 4.01.xx
    Version 1.00.xx (driver 2)"

Given I'm unsure which if any was installed, which should I run please?

I have discovered only one hit in Synaptic searching on 'Samsung':
"PACKAGE: printer-driver-splix
VERSION: 2.0.0+svn315-2fakesync1
DESCRIPTION: Driver for Samsung and Xerox SPL2 and SPLc laser printers"

Should this be left or uninstalled separately please?

I do like this site - clear, precise and uncluttered.

After many many tries at getting the SCX-4100 to scan I can't remember what I've installed. The directions say "... installations of the Unified Linux Driver performed using the Samsung installer ... must be completely removed before using the .debs in this repository"

Q: is there a Synaptic [or even Terminal] input/command that will identify what relevant packages need to be removed?

Quite probably a silly Q for anyone more familiar with Terminal.

A/ Downloaded:  -i suldr-keyring_2_all.deb [Firefox dumped it in Desktop]
B/ input: ~$ sudo dpkg -i suldr-keyring_2_all.deb
C/ Output: dpkg: error processing archive suldr-keyring_2_all.deb (--install):
cannot access archive: No such file or directory
Errors were encountered while processing:  suldr-keyring_2_all.deb

Is this as simple as moving the download somewhere? If so where please? detailed Terminal instructions would be appreciated : I also have Synaptic.
