Sounds to me like that there is a small buffer in the device driver
(scsi/pp/etc) or the reading process (SANE backend) is requesting little
chunks of data. Irregardless, you *should* end up with an image...hmmm,
you might have another issue.
I've experienced much of the same issues while writing my USB device
driver and trying to find an optimal read buffer.
