It seems so, but binary does!
Binary image is 2479 pixels wide and pixma has 2552 pixels. It seems
that binary crops image width to hide ADF frame and pixma doesn't.

It seems that ADF cannot scan whole page length. Binary crops here, too.
Pixma saves the expected image height of 3508 pixels.
You can investigate this behaviour @ 75 dpi, if you like. Otherwise you
can set the scan size (x, y positions and width, height) in the frontend
to crop ADF frames by yourself.
I prepared a new patch with these fixes (based on patch 2):
(1) remove s->param->adf_pageid to avoid doubled coded functions.
(2) all ADF scanners support 14" legal paper size in ADF mode, but only
A4 in flatbed mode.
Please test this patch again and try to use it in your productive work.
If everything is OK, I'll commit this patch and we can close the ADF
paper empty issue.
Many thanks for your help.
Cheers,
Rolf
