I just scanned approximately 200 pages in Ubuntu 12.10 with no problems,
using 3.02 package from the repository. I had to use convert to improve
the tiffs from my scanner, but I got very good results, with a very low
error rate. Didnothing special.

I have Ubuntu 12.04, which has tesseract 3.02 and leptonica version 1.69.
I've installed these, and also installed libtiff4 using apt-get.
When I try to process a document, I get:
↪ sudo tesseract united_states_v._ups_customhouse_brokerage_inc.tif
Can you send and example of you tif file?

It's about 300MB, unfortunately, but I generate it programmatically using
imagemagick in a way that's worked in the past, so I don't think the tiff
file itself is the issue.
If you're willing to download this monster, I'll post it to dropbox. I'd
love the help, but I don't think it's the right
Are you able to generate just one page or small example? Or can you provide
step how you create it (so I can create it)?
Tiff could be tricky. E.g. libtiff-4 do not work for me...

Sure, that's a good idea.
Here's the original PDF:
http://courtlistener.com/pdf/2008/05/28/united_states_v._ups_customhouse_brokerage_inc..pdf
If you download that, then run:
convert -depth 4 -density 300
united_states_v._ups_customhouse_brokerage_inc..pdf
BTW: spp means Samples-per-pixel[1]. Are you able to instruct imagick to
use 1,3 or 4?
And I found report on stackoverflow[2] - there mentioned that imagick use
to set spp to 2, which should be invalid for tiff...

OK, we're getting somewhere!
I figured out that the Ubuntu repo just doesn't work properly with tiffs,
and recompiled and installed tesseract and leptonica.
So now when I run tesseract -v, I get:
↪ tesseract -v
tesseract 3.02.02
leptonica-1.69
libjpeg 8b : libpng 1.2.46 : libtiff 3.9.5 :
Looks like I'm all set.
I had to remove -flatten from the command above, and all is working now.
Thanks so much for the help.
