I bought a Minolta PS3000 scanner. It's an antique (older than half you young fella's around here :) ) books scanner, has the overhead camera thing. Seems Minolta doesn't support it anymore.
It scans at 400DPI bitonal (black and white) which should be plenty for what I need, which is basically just a readable copy of the page.
However when I scan a page, I end up with an image that looks like it's been dithered, or halftoned. Or something. I'm not a scanner expert, but it's definitely too light. I posted at this thread where you can see a pic of one of the images:

That image is clearly not good enough, particularly for OCR. The scanner has settings for text, image, or B/W (though I think all three settings start with bitonal) and I don't think the scanner does greyscale - I don't think anyway.
That's a long way of asking - any thoughts on what I'm doing wrong here? Or am I not doing anything wrong and that's the way the pics are supposed to look (don't think so though - I did a 400DPI b&W scan on a different scanner and it was way nicer).
