Simple Scan and HPLIP do not recognize my scanner

Asked by Lefol Laurent

I own an HP Officejet 6500 A. I use Ubuntu 18.04.1 LTS. dpkg -l hplip says that HPLIP (3.17.10+repa) is installed. I suspect that HPLIP is not installed properly.
The printer is connected to my Ethernet network and works fine for printing tasks. However the scanner is not recognized (I use Simple Scan). The scanner used to work when I installed Ubuntu and HPLIP the first time. But I had a message at boot "Systray missing". I also had error messages regarding Python at every Ubuntu update. I tried to fix it, uninstalled HPLIP and re-installed it but I guess I did something wrong as I am very novice with Linux.
hp-check -t provides an error message: error: Unable to locate models.dat file
Here is the log:
Any help will be appreciated.

I finally managed to solve my problem. I downloaded hplip-3.18.9.run and installed it following the instructions given at https://developers.hp.com/hp-linux-imaging-and-printing/howtos/install#howtocheck2
The automatic installer managed to uninstall my previous hplip version.
It worked fine apart from some minor issues. Printer and scanner work now.
