[sane-devel] scanimage does not scan the whole page

[Cornelius Koelbel]

Hello,

here I am again with a new problem.
I got my scanner a USB Cannon CanoScan N670/676U  with the plustek 
backend, scanning now.

But when I issue the command scanimage --format tiff --mode Color > 
test.tif,

I get only a small portion of the image (240x160), not the whole page.

What do I have to do to get the whole page?

Thanks
Cornelius
