I upgraded Ubuntu to 12.04 from 11.10. The printer works, but the scanner doesn't now. In 11.10 I had to install a special driver from Brother. The printer's model is Brother MFC-290C. The computer is a Toshiba Satellite. How can I get the scanner working?

Update:

I have a 64-bit installation on the Toshiba Satellite. Thank you for your instructions, Chad--24216. I followed each step: 1 through 5. I also updated the Brother Linux scanner S-KEY tool.

The output of dpkg -l | grep Brother is:

Still the scanner does not work. Here is the message from Xsane:

Failed to open device brother3:bus6;dev1:  Invalid argument.  

Here is the message from Simple Scan:

Failed to scan. Unable to connect to scanner.  

And Scan Utility still doesn't display the scanner line.
