Ubuntu 17.10 and Samsung SCX-4624F Scanner not working

Question

After I installed Ubuntu 17.10, Samsung SCX-4624F Scanner stopped working. What is strange after many tries I scanned one page but couldn't repeat this. After system reboot scanimage -L listed the scanner once and then scanner disappeared.

Answer 1

It turned out that in SANE 1.0.27 released in May 2017 had some USB fix disabled (printer/scanner with USB 2.0 has problems with USB 3.0 port).

It is possible to enable the fix with the new environment variable SANE_USB_WORKAROUND=1. After I added it to the .bashrc, Simple Scan started to work correctly.

Also for me the scanner is not working with samsung scx 4200 but for waiting the solution i find this way :

1) mache a script (for example scanner)

2) inside the script I insert this :

#!/bin/bash
echo "insert path and file name extenction .pnm"
cd /home/YourHome(change this with your home)
read -p "insert:" PathName
echo $PathName
export SANE_USB_WORKAROUND=1
scanimage >$PathName
read -rsp "press a key to terminate" -n1 key

in this way I can scan my document and is working, off course I ave to convert then but this is not a problem

Have you tried using the Ubuntu application "Simple Scan" ?. It is in Ubuntu software center. It works for my old HP all in one Printer.
