How do I load paper in the built-in sheet feeder?

First set the paper release lever to the single sheet position and set the thickness lever appropriately based on your paper type (0 for plain paper, + for envelopes or heavy paper). Load a stack of paper with the printable side face down and slide it all the way into the feeder, then adjust the edge guides to match your paper width. Do not load paper above the arrow mark on the right edge guide. (Page 51-55)
