drivers - Brother MFC-295CN Scanner

I have managed to add my MFC-295CN printer to my Ubuntu 11.04 desktop. However, I need some help adding the scanner.
from the Brother website I am instructed to install the driver
step 4-3) Command (for dpkg)

# dpkg -i --force-all (scanner-drivername)

and the example given is:

dpkg -i brscan-skey-0.2.1-1.i386.deb 
Selecting previously deselected package brscan-skey.
(Reading database ... 89058 files and directories currently installed.)

Unpacking brscan-skey (from brscan-skey-0.2.1-1.i386.deb) ...
Setting up brscan-skey (0.2.1-1) ...

With terminal I can add PPA's and remove programs but this is very confusing to me. Do I write the '#'? do I need to type 'sudo'?
FYI I need to download the brscan3 driver. Please help me with this, once I get this I won't need Windows 7 really anymore, being able to scan from Ubuntu would be a huge win.

Thank you,

Dustin
