Problems with Brother MFC-J430W

[jabberwock359]

Hi folks,
I've just run through the linux mint trouble shooter for my printer and ended up with this diagnostic output (sorry! its long) its possible the crucial bits are further down, not sure!
Is there a linux saint out there who wouldn't mind having a little scroll down to tell me what I might try? thanking you heaps in advance!!
