Rear Stacker (face up), Capacity100 sheets 20-lb. US Bond
(75 g/m²) paper
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.
