I changed the page to have thumbnails.
I have been doing more testing and the problem is reproducible even when I am scanning something as small as 603x610 pixels at 900 DPI. I also tried scanning in gray scale at more than 900 DPI and it appears that the image is clipped at the right boundary.
I can live with this, but, I'd like to help fix it. Any advice?
Many thanks,
Jeff
