6.4.2.1 Paper Exit Path

The paper exit path for the paper output from the printer varies
depending on the paper ejection mode. Sensors and switches monitors
if the paper is being transported along the correct path. The paper paths
and involved parts are as shown in the following figure.

A sheet of paper output from the printer enters the 5-Bin Unit if the
Transfer Switch Guide Lever is lowered (in the mode other than duplex
mode). The paper path hereafter depends on the paper eject mode.

5-Bin Unit
In the normal ejection mode (Face-down Bin 1) or shift mode, the paper
guide switches to the lowest position, from which the paper is
transported to the Bin 1 and then ejected to the tray in the Bin 1 by way
of the Eject Sensor, Eject Roller, and Paper Empty Sensor. In the shift
mode, the tray in the Bin 1 moves right and left so paper can be output
to each side alternately.
In the mail box mode, the Paper Guide and Transfer Switch Guide
Lever moves/switches in accordance with the bin selected. The paper
guide switches between four positions as follows; for Bin 2 or Bin 3, the
Paper Guide Switches to the second or third position from the bottom.
For the Bin 4 or 5, it switches to the top position and the Bin 4/Bin 5
Switch Guide Lever also switches to the position for the corresponding
bin. The paper, after passing the Paper Guide (Bin 4/Bin 5 Switch
Guide), is ejected to the tray in the selected bin via the Eject Sensor,
Eject Roller, and Paper Empty Sensor.
If the Eject Sensor does not detect the paper within a specified period of
time after the Paper Eject Sensor in the printer is turned on, it is
considered as a paper jam error condition at the entry or exit part of the
5-Bin Unit.
