xsane does not find HP_LaserJet_Pro_MFP_M225dn scanner on the network

[Jan Zegers]

I upgraded from Ubuntu 17.04 to 17.10 and my working HP scanner stopped being detected. I understand that hplip is not yet supporting ubuntu 17.10. Any clues on how to solve this??

You installed an up-to-date plugin?

Anyway, detection should take place with AirPrint activated on the device and with

scanimage -L

scanimage -L

No scanners were identified. If you were expecting something different,
check that the scanner is plugged in, turned on and detected by the
sane-find-scanner tool (if appropriate). Please read the documentation
which came with this software (README, FAQ, manpages).

The plugin is up to date.

The printer is connected to the network with an ethernet cable and is reachable. I don't see what AirPrint has to do with the problem?

Hi,
The Ubuntu 17.10 support has been planned in the 3.17.11 release in the month of November 2017 and it will address this issue.
Can you please check and update whether the hpaio.so files are available in the /usr/lib/sane path?

Thanks,
Badal

Your device does Bonjour broadcasting. The scanner should be picked up with

avahi-browse -art (look for _scanner._tcp).

scanimage should detect the scanner with libsane-hpaio on the system. HPLIP has been designed to do this.

Hello Jan.

Do you get any messages from hpmud in journalctl or syslog when 'scanimage -L' fails to detect the scanner?

Supose you were to edit /usr/share/hplip/data/models/models.dat and alter [hp_laserjet_pro_mfp_m225dn] to read [laserjet_pro_mfp_m225dn]. Does 'scanimage -L' work now? And can you scan?

Cheers,

Brian.

Hello friendly helpers,

I was able to solve the problem. I removed the hplip* packages (sudo apt remove hplip hplip-data hplip-doc hplip-gui) and reinstalling it. Subsequently, I manually moved /etc/hp/hplip.conf.dpkg-dist to hplip.conf. I subsequently reinstalled the printer with hp-toolbox and now it recognized the printer. xsane is working also.

The only error I now have is:
error: No system tray detected on this system. Unable to start, exiting.
But this is not important.

Thank you for your support and ideas for resolving the problem. You may consider it as resolved.

Kind regards,
Jan
