[ubuntu] Canon MF3010 printer ok - scaer problem

I have just installed Ubuntu 14.04.4 LTS 64-bit. I have a Canon MF3010 printer/scaer and got the printer part working by installing the deb drivers (link here) from the Canon website. Really this was completed by double clicking on the cndrvcups-common_2.70-1_amd64.deb and cndrvcups-ufr2-uk_2.70-1_amd64.deb packages in this order. This then went through the Ubuntu Software Centre and was installed. In fact now I have two printer setups with almost the same properties. This may be due to what I did when I tried to resolve the scaer problem through another link (see below):

Printer 1: Canon-MF3010
Device uri: usb://Canon/MF3010?serial=014B40000BF0&interface=1
Make and model: Canon MF3010 ver.2.7

Printer 2: Canon-MF3010-2 (now set as default)
Device uri: cnusb:/dev/usb/lp0
Make and model: Canon MF3010 ver.2.7

The problem is now with the scaer. I looked online and found a few posts but followed the instructions in this one which was exhausting, although I did not really understand or follow the Idea below it (see my results below - personal information removed):

useame@pcname:/usr/lib/x86_64-linux-gnu$ scanimage -V
  
scanimage (sane-backends) 1.0.26git; backend version 1.0.26
  
useame@pcname:/usr/lib/x86_64-linux-gnu$ sudo scanimage -L
