Hello Roger,

Thank you. I've just tried by adding hpaio in /etc/sane-d/dll.conf. It
did not avail.

However, I shall note that this scanner is supposed having the backend
of avision. And avision is listed on /etc/sane-d/dll.conf.

Can someone provide a tip to troubleshoot the scanner?

Kind regards,
