This is the page I'm trying to scan in (shown here at 150 dpi, color, no problems):
That costs 213kB though. The content is not so hot, so I'm happy with 75 dpi, greyscale. However, when I try that, HP gives me :
Yuck! 42 kB of junk.
However, if I do a preview with color mode and then, after the preview is done, I choose custom settings with 75 dpi and greyscale, the image comes out fine. What gives?
Problem with a Hewlett Packard product.
Workaround - use preview, then scan in Custom, then, hit the back button and change the object, and do "Next" - in essence - keep that one dialog open forever and you'll be cranking like Nanking.
