SCX 4500 on ubuntu 18.04.01 on USB

[yanndan]

Hello all,

I have updated my ubuntu version from 16.04 to 18.04. It appears that the scanning function does not work anymore. I have a I/O device issue (see the end of the message for the log from simple scan).
My printer/scanner is plugged in USB.
I installed the drivers v1.00.39 from this webpage: https://support.hp.com/us-en/drivers/selfservice/closure/samsung-scx-4500-laser-multifunction-printer-series/19135297

I added the lines to libsane.rules files (I added old and new version since I was not sure):
________________________________________________________________________
#https://doc.ubuntu-fr.org/tutoriel/installer_imprimante_samsung
# Samsung SCX-4500
ATTRS{idVendor}=="04e8", ATTRS{idProduct}=="3426", ENV{libsane_matched}="yes"
ATTRS{type}=="3", ATTRS{vendor}=="04e8", ATTRS{model}=="3426", ENV{libsane_matched}="yes"
#ATTRS{type}=="3", ATTRS{vendor}=="Samsung", ATTRS{model}=="SCX-4500", ENV{libsane_matched}="yes"
________________________________________________________________________


I added a symbolic link to make it detected by simple scan:
________________________________________________________________________
sudo ln -sfr /usr/lib/sane/libsane-smfp* /usr/lib/x86_64-linux-gnu/sane
________________________________________________________________________



I launched simple-scan as a root because I wanted to be sure that was not a permission issue. Below are the lines of the log

Do you have any idea how to solve this issue?

Hello all,

I have a weird issue.
The scanner worked in command line with scanimage but not with simple scan or xsane. After a reboot, it did not work anymore with any programs.

Kind Regards,

Hi pat,

Thanks for your answer but I still cannot scan with linux. I also tried with linux mint and I have the same issue. There is something that bother me: it worked yesterday but it does not work today. I did not change anything in the configuration.

Thanks for everything.

It's not the same scanner (SCX 4500 <> SCX 4705).
In my case I also had to install "suld-scanner-usblp-fix". You can try to change usb socket, if possible directly on the motherboard. Check this page https://www.bchemnet.com/suldr/scanning.html
