penny-farthing It doesn't look like you try to scan any document from the debug trace. I honestly don't know if this will help solving your problem or I will be able to solve it for you. But if you want to indulge me in this pursuit. Please try these steps :

  1. Uninstall sane-airscan. sudo eopkg rm --purge sane-airscan . Make sure it is not installed.
  2. Make sure sane-backends is installed.
  3. From terminal run simple-scan --debug
  4. Try scan a page with "Single Page" option.
  5. Try scan a page with "All Page from Feeder" option.
  6. Try scan a page with "Multiple Page From Flatbed" option.
  7. Close simple-scan.
  8. Post that log here.
  9. Now, install sane-airscan. Check if there is any other scanner in the dropdown-menu. If there isn't, just select the previous scanner.
  10. Redo Step number 3 until step number 8.

      Not trying to interupt this may be something to try at some point.

      Go to system printers and then your printer details and get the address of printer mine looked like this
      Brother MFC-J680DW.ipp.tcp.local.

      Then in terminal run (simple-scan airscan: Brother MFC-J680DW.ipp.tcp.local)
      I had 2 entries airscan and eSCL select airscan and see if that works.

      Just info

      Note I forgot my brother scanned dont use it to ink hungry but I tested the above and it worked
      for me

      Note might run (scanimage --list-devices) to make sure you have an airscan device listed

        The logs are substantial and I've recorded them by copy/paste into a .txt file via gedit.

        Problem: when importing the file into this post, the following message appears => "Uploading files of this type is not allowed."

        How can I report the results of the tests you asked me to carry out?

            penny-farthing I wasnt expecting that start simple-scan and see if changes the address
            if it does thats what you want where it says localhost. (let me know either way could make difference)
            It should change meaning it found the scanner.

            Note then close simple-scan and try that from terminal
            Oh type it just like it shows

              Awaiting your analysis and thanking you in advance.

                  @penny-farthing Sorry I will be not be able take a look at this for a few days. I made a big mistake on my PC. Cheers!

                    penny-farthing Copy like a copy machine
                    Like on mine if I need a copy of something I can do it from the printer itself.
                    The reason being wanted to make sure it wasnt hardware from the log you posted.
                    Does your printer have that feature.
                    Printing doesnt use the scanning hardware.
                    Thanks

                        My printer's menu includes a Copy function (black & white or color) with the option of setting the number of copies.

                        I tested this function by placing a document on the glass on top of the printer and asking for 2 copies. The document was printed as requested, with no downtime.

                            @penny-farthing Ok, I just got my computer back. Unfortunately, I couldn't find anything different from your logs😢. I also just realize that sane-airscan is only useful if you connect your printer via network (Wifi/LAN). Maybe try connecting your printer via Wifi ? Then install sane-aircscan and see if simple-scan will show that "eSCL -Your Pinter Name" option in the drop down menu. This is the last one, I don't know any other solution. Maybe someone else have more knowledge on this than me. Sorry if this is not helpful after all. Cheers!

                              Unfortunately, I will not be able to follow up on your request, because my printer is not planned to operate in WiFi. I will therefore uninstall the sane-airscan package, since in my current config, it is not useful to me to keep it.

                              Thank you anyway for trying to help me.

                              I'm leaving this post open in case someone can suggest another way forward and I'll be using the Skanpage sofware in the meantime.

                                Precision:
                                In the meantime, I have managed to install simple-scan in flatpak version after uninstalled that of the Software Center) and there, from the launch of the application, it tells me the following message:
                                "Aucun périphérique de numérisation détecté." (No detected scanning device.)
                                while my printer is properly connected to a USB port on my computer.

                                Below, the logs when startup the application in a terminal session:

                                administrateur@solus-budgie ~ $ flatpak run org.gnome.SimpleScan
Gtk-Message: 13:55:21.304: Failed to load module "xapp-gtk3-module"
Gtk-Message: 13:55:21.334: Failed to load module "canberra-gtk-module"
Gtk-Message: 13:55:21.334: Failed to load module "canberra-gtk-module"
administrateur@solus-budgie ~ $

                                So I uninstalled it and reinstalled the Software Center version while waiting.

                                the canberr stuff is normal.
                                have you tried gscan2pdf in our repo?

                                  I have been full circle so many times on this because its not a real clear issue
                                  Tried running hp-check -t or -r on my hp laser/no scan their was so much stuff and errors could not
                                  tell anything concrete.
                                  In the log she posted its says device busy error if the printer isnt showing that in display its going to be a software thing.
                                  Have not connected dots yet.

                                    brent

                                    The installation of gscan2pdf generated 36 packages.

                                    The launch of the application generated the following message:


                                    (but the pdftk package does not exist in the Software Center)

                                    Then arrived on the interface, when scanning the 2nd page, the following error message appears:


                                    but the page is well scanned.

                                    Please note:

                                    • The quality of scanning of pages with gscan2pdf is less good than with Skanpage

                                    • gscan2pdf allows you to scan the image of a webcam.
