This would work outside/avoiding the models.dat file model. However I cannot find the acceptable config option to suggest a change in timeout to `/etc/sane.d/hpaio.conf`.
Maybe someone would be better at discovering the SANE documentation for the `hpaio` backend than I am.
It seems to me the error is of SANE timing out prematurely, as if it assumes the `hpaio` class all have automatic feeders.
It wouldn't be the first time a timeout needed to be adjusted: /unix.stackexch ange.com/ questions/ 349850/ xsane-error- during- read-error- during- device- i-o-canon- pixma-mg3550- scanner
