1. install these packages

   apt-get install sane sane-airscan
   

2. add the scanner name and URI you got from the airscan discover command to the configuration file. In this example the scanner name is scanner name and the URI is http://192.168.0.1:60000/eSCL/

   /etc/sane.d/airscan.conf

   [devices]

3. open one of the scanner apps such as simple-scan

   apt-get install hp-ppd hplip hplip-data libhpmud0 sane
   

2. reinstall libsane-hpaio as suggested by reference 1

   apt --reinstall install libsane-hpaio
   

3. comment all backends in /etc/sane.d/dll.conf

4. you should have a file in the SANE configuration, like this

   /etc/sane.d/dll.d/hplip

   # dll.conf snippet for hplip
   #
   
   hpaio
   

5. check if scanimage detects the scanner in a matter of seconds

   scanimage -L
   

6. check if remote scanning still works
