Reverse Engineering the Brother MFC-7400C

I have an old Brother MFC-7400C, which doesn't work as a printer or fax machine anymore, but the document feeder makes it useful for scanning multi-page documents. Unfortunately, it doesn't seem to be supported under Linux, so I figured I'd try writing my own implementation by reverse engineering the scanning protocol.

SniffUSB was used for analysing the USB traffic. By obtaining logs whilst various operations are performed with the scanner, it is possible to determine the characteristics of the protocol relatively easily.
