Abstract
A sheet stacking tray assembly may include a tray having a lead edge surface, a tray exit ramp having a first end and a second end, and a feeder having a feeder edge. The first end of the tray exit ramp may be configured to connect to the lead edge surface. The tray exit ramp may be convex relative to the lead edge surface and may extend beyond the lead edge surface. The tray exit ramp may include one or more first anti-stub surfaces, that may be configured to be positioned below a lead edge of a sheet in a sheet stack. The feeder edge of the feeder may include one or more second anti-stub surfaces that are complementary to the first anti-stub surfaces. The feeder edge may be configured to interconnect with the second end of the tray exit ramp to form a transition surface.
