Either you have chosen to skip the Plug-in installation or entered incorrect Password.
and the scanner is not functionning with sane.

Please try to install plugin file using below command:

sh hplip-$

It should install plugin file properly. If you face any issue after this please let me know.

Sorry, but I do not have a file on my computer.
I tried from command-line hp-plugin but same problem with keys from hp authorized server. I think the simpler would be to download plugin files on my computer by any mean and then from hp-plugin use "Select and install an existing local copy of the plug-in file".

Today, using hp-plugin -i I succeed to download plugin files from hp server, but after giving my sudo password, the program crashed. So I tried again and after downloading plugin I copied ~/.hplip/plugin_tmp and then launched from this directory hplip-plugin-install. The installation succeed and I can scan, but after each scan, I have a message from sane : "input-output error" but it's OK, I can use the scanner.
