Hello, Same bug here with a Deskjet F4500. As a workaround I can use Webscan by entering the IP address of the printer in Firefox URL bar. -- Léo

Bug#961028: hplip: No scanner found: SANE cannot load the hpaio backend
Package: hplip Version: 3.20.5+dfsg0-2 Severity: important Dear Maintainer, The current version of hplip seems to come with a non functional libsane-hpaio. This bug happens with a printer-scanner model. The CUPS print queue is configured using hp-setup and works well. The scanner is not detected anymore since the latest upgrade from 3.20.3+dfsg0-2 to 3.20.5+dfsg0-2. Running "scanimage -L" does not detect any device. I've also tried (removed lines are about other backends): # export SANE_DEBUG_DLL=128 # scanimage -d 'hpaio:/net/Officejet_Pro_8600?ip=192.168.0.21' [sanei_debug] Setting debug level of dll to 128.

I've finally manually downgraded libsane-hpaio to version 3.20.3+dfsg0-2 (and only this package, keeping 3.20.5 for other hplip related packages). The scanner works fine again.
