Thanks. The first log was probably sufficient, but the ensuing ones will
probably make good supporting data should it be needed.
I took a look and indeed it is similar to existing code. As a matter of fact,
I'm still deciding whether it's more similar to the MF4270 or the MP730. One
of the key diffs between the MF4270 is the checksumming; in yours, it just puts
a checksum at the end like other Pixmas while mine is weird in that it puts the
inverse at the end and the regular checksum before it.
Anyway, I'll dig into it more tomorrow. If you don't mind, I'm also cc'ing the
list and attaching an abridged version of the log for posterity and in case
anyone else wants to weigh in on the protocol.

Subject: Re: [sane-devel] Canon MF4140
Got a couple more. 150dpi color from the bottom of the scan and 300 dpi b/w
along the left edge.
This enough to get you started?
