Hello Jan,

can you try to reinstall your printer (or reinstall hplip), follow one of ways in http://hplipopensource.com/node/309 to install your plugin and restart your printer after that, please? It seems the problem is in plugin.

Comment 2 Jan Včelák 2016-06-20 09:42:28 UTC

Hm. I don't have the plugin at all. I didn't know the plugin is needed for scanner to work. And no log message indicated that.

Let me check tomorrow if it works with the plugin.

Comment 3 Jan Včelák 2016-06-21 11:31:43 UTC

Installation of the plugin indeed solved the problem. Thank you, Zdenek.
