Sorry Ed, you missed something.

It's 62ppm *duplex*. That means only 31ppm single-sided.

The Canon is 3x faster for only $300 more - 90ppm single-sided, 180ppm
duplex. Again, what's happening here is that the mechanical paper
handling is the hard part, the actually scanning is easy, so they quote
ppm rates in "duplex" to make it sound faster (classic marketing). And
the Canon paper hopper is bigger (at least 500 sheets vs. 300 and to be
honest I wish 1,000 was available at a good price point). Finally, the
Panasonic you mention does paper to legal size (8.5x14) where the Canon
can hit 11x17 (and I can think of at least one potential application for
that).

Like I said, the Canon is a hell of a deal if we can sort out the drivers.

Another point on that: Canon execs must be aware of the "controversy"
surrounding US voting systems, at least the US side managers and word of
the issue has probably gotten to Japan by now. Canon might like the PR
benefits of being tied to a "white hat solution" and hence help out with
driver R&D - esp. since the same R&D gives them the Linux market...

-----------------------

Sidenote on software design: we could set it up to scan both sides,
throw out blank sides in software while counting the number of same, and
as long as the number of discarded blanks equals the number of data-rich
sheets we know there wasn't a jam or anything AND we can work with
ballots that were stuck in upside-down, rightside-up, maybe even
backwards if we're clever enough and have an "orientation symbol"
somewhere to reference. Now the county elections staff can cram 'em in
there any ol' way! :)
