Setting up MFC-420cn scanner

I'm new to Ubuntu and Linux based systems and have been trying to get my Brother MFC-420 cn scanner working again. I had it working on 11.04 until I upgraded to 12.04 lts. I set up in Xsane and it finds the scanner. I choose the scanner and xsane goes to work and an error comes up that says Failed to open device brother2:bus5:dev1 Invalid argument. When I go into the terminal and use sane-find-scanner the result comes up:

  # sane-find-scanner will now attempt to detect your scanner. If the
  # result is different from what you expected, first make sure your
  # scanner is powered up and properly connected to your computer.

  # No SCSI scanners found. If you expected something different, make sure that
  # you have loaded a kernel SCSI driver for your SCSI adapter.

found USB scanner (vendor=0x04f9, product=0x0162) at libusb:004:003
  # Your USB scanner was (probably) detected. It may or may not be supported by
  # SANE. Try scanimage -L and read the backend's manpage.

I then ran scanimage -v with the result:

This is sane-find-scanner from sane-backends 1.0.22

  # sane-find-scanner will now attempt to detect your scanner. If the
  # result is different from what you expected, first make sure your
  # scanner is powered up and properly connected to your computer.

found USB scanner (vendor=0x04f9, product=0x0162) at libusb:004:003
  # Your USB scanner was (probably) detected. It may or may not be supported by
  # SANE. Try scanimage -L and read the backend's manpage.

running scanimage -L returns:

device `brother2:net1;dev0' is a Brother MFC-420CN MFC-420CN
device `brother2:bus5;dev1' is a Brother MFC-420CN USB scanner

I ran sudo gedit /lib/udev/rules.d/40-libsane.rules and added:

# Brother Mfc-420cn
ATTRS(idvendor)=="0x04f9", ATTRS(idproduct)=="0x0162", ENV(libsane_matched)="yes" betrween where usb starts and usb end

Checking SANE"s supported scanners the MFC420cn is not supported. I managed to get it working before in 11.04 by adding the scanner to libsane rules

Do I need to move the scanners location from
found USB scanner (vendor=0x04f9, product=0x0162) at libusb:004:003 to /dev/usbscanner or, is there a way to direct xsane to find the scanner?

Also when I run the brsaneconfig2 is says the mfc-420cn is registered.
