Hopefully you don't have a great deal of prints with this paper. As TCouch shows with the specs, don't plan on tray 2. With tray 1, you'll most likely have to feed it one piece at a time. We've put some pretty heavy card stock through, sometimes even successfully! But it is a slow process. I suggest, if possible for this printing, to use letter size instead of, say, a 4x6.
And experiment with the paper settings. Don't feel like you have to use the card stock setting. Sometimes the rough paper setting helps, as does the label setting. Make sure there is little to no curl to the paper.
We've had this model for a couple of years now and have pushed some limits on different weights (plenty of 80# and above) and textured papers. It doesn't like to be aggravated too much, so good luck.
