Comment 49 for bug 1847142

For those like me who look forward a solution to make HP scanjet pro 2500 f1 device working, here is a working process (thanks to that post : https://gitlab.com/sane-project/backends/-/issues/150).

I'm on Kubuntu 20.4 x64, Those steps where OK :

    sudo apt install hplip
    sudo apt purge hplip
    sudo apt autoremove
    sudo rm -rf /usr/share/hplip
    sudo apt install libsane-hpaio

hp-plugin couldn't download automatically so I had to get it from : https://developers.hp.com/hp-linux-imaging-and-printing/plugins And download 3.20.3 version of the two files hplip-3.20.3-plugin.run hplip-3.20.3-plugin.run.asc to make it compatible with distro packages. Then :

sudo hp-plugin -i

Indicate "p" to give path and if you're in the right folder, a dot as path : .

scanimage -L

detects the scanner

Many posts suggest simple-scan (sudo apt install simple-scan) but I could not manage to scan multiple pages on "simplex" mode...

kscanlite works well but you have to make a first preview to select A4 area and unfortunately, it doesn't remember the area after relaunch.

Xsane (my favorite) works well too but I had to understand how to make it work with multiple pages scanning as I had only first page scanned :

    At first use, in the view window, select A4 and drag&drop the A4 area,
    On the main window, select "multiple page" (opens a new window),
    Select ADF Simplex (or duplex),
    On the main window, upper-left corner, select the number of pages to scan (or any number higher),
    On the multiple-page windows, give a path and a name to the project and "create" project,
    Launch scanning,
    Save multiple page file.
    You will have to delete project to start a new multiple page scan.

Best regards
