When the rear paper stacker is folded down, paper exits the printer
through the rear of the printer and is stacked here face up. This is
mainly used for heavy print media. When used in conjunction with the
Multi-Purpose Tray, the paper path through the printer is essentially
straight. This avoids bending the paper around curves in the paper
path and makes paper feeding more reliable.
