How do I load paper in the rear paper feeder?

Flip the feeder guard forward and raise the paper support, then slide the edge guides all the way out. Fan the sheets if inserting a stack and tap them on a flat surface to even the edges. Insert paper glossy or printable side up and short edge first at the center of the paper support. Slide the edge guides against the paper but not too tightly, and select the paper size and type on the LCD screen if prompted. (Page 46)
