Thanks for the tip. I've also been told that humidity change can cause the paper to curl that slight bit.

Side note: The Kyocera-Mita 6330 copier/printer/scanner at my office has clocked over 650k pages in its two years so far. It's had about 1/100000th as many jams. (watch me have done that math wrong...) Shame on HP for making us change imaging drum with toner after 3,000 pages when my Kyocera-Mita drum lasted 500,000 pages.
