That's _LOSSY_ JBIG2.
YOU DON"T HAVE TO USE LOSSY MODE!
Don't shout!!
And for the topic: you don't have to use JBIG2. Space isn't really an
issue today for scanned bilevel documents, so you can just stick with TIFF
G4 or PNG.

PS:
You should have a look at the netiquette that says "Only post with a
name" and "Be polite, don't shout".
