I assume the scanner works properly in the same configuration on Windows? Just to be sure it's not a hardware issue.
I don't have anything with Windows on to try, however I am confident that it is a software issue as I was scanning some things one morning, then happened to do an 'apt-get upgrade', just after then went on to continue scanning and found the problem as described.
Then, could you please attach the files /etc/sane.d/dll.conf and /etc/sane.d/dll.conf.d/hplip?
Attached as requested, although I take it that you meant /etc/sane.d/dll.d/hplip as I don't have a dll.conf.d
And provide the output of:
