You could install the newbiedoc package. Section 5, 'Help with multimedia in Debian', has a section called 'How to install a scanner in Debian GNU-Linux using Sane'. It offers step-by-step installation instructions, checking every step. It helped me install my HP ScanJet 5200C. It works fine in both stretch and buster.
