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