Thank you! I'm going to do some fiddling with it tomorrow, earlier in the day, when I'm a bit sharper. And I'll take your suggestion to email HP for advice.

I typed in "contrast", and thought I hit the jackpot, but the information was for scanning, not printing.

It MUST be something I'm not doing, because, again, it got such good reviews. The one I just scrapped was an HP, and I had it for seven and a half years.
