Hi Frank,

Lide 300 supports IPP over USB, and eSCL on a top of it. The presence of 
the IPP-over-USB support causes ippusbxd daemon to start, which 
effectively blocks sane-pixma driver and should, in theory, enable 
sane-escl driver, which seems doesn't want to work.

You have two possibilities here:

1. Remove ippusbxd in a hope to unblock sane-pixma:

     sudo apt-get remove ippusbxd

2. Replace eSCL/IPP-over-USB stack with the modern alternative. First 
step as above (remove ippusbxd), then download and install ipp-usb and 
sane-airscan packages from the following location: 

Note, both of these packages will be officially included into the 
subsequent release of Ubuntu, so you will not be locked with some 
strange 3rd party packages.


	Wishes, Alexander Pevzner (pzz at apevzner.com)
