The Paper Exit Unit has a Paper Exit Sensor Feeler. The Paper Exit Sensor detects if there is a sheet of paper in the output tray by detecting the orientation of the Paper Exit Senser Feeler. When printing one-sided copy, the paper passes under the Duplex Junction Pawl and is then transported to the Paper Exit/Reverse Roller before being ejected.

When printing two-sided copy, on the other hand, the paper passes over the Duplex Junction Pawl and the Paper Exit/Reverse Roller, and thereby the unit performs a switchback. When the height of the paper stacked in the Paper Exit Tray exceeds a certain level, the Paper Full Sensor detects that the paper height in the output tray has reached the limit by sensing the position of the Paper Full Sensor Filler, and then the printing operation is stopped.
