Operating principles

6.5.2 Mechanical Operations

6.5.2.1 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.
When the 10-bin Unit is used, the entry part of the Horizontal Transport
Unit is lowered by the Paper Path Switch Solenoid's operation to send
paper out to the Bin 1. In the sort mode, the entry part of the Horizontal
Transport Unit is also lowered so the paper from the printer advances to
the Tray section through the Horizontal Transport Unit to be ejected to
the bin.
If the paper fails to pass the PC1 and PWB-C within the specified period
of time after the Paper Eject Sensor in the printer is turned on, it is
considered as a paper jam condition at the entry or exit part of the 10-
bin Unit.
The paper from the Horizontal Transport Unit is sent to the Tray Section
by the Transport Roller. The paper path after this point varies
depending on the paper ejection mode. The paper is output to the
selected bin via the Eject Sensor, Eject Roller, and the Paper Empty
Sensor. If the paper fails to reach and pass the Eject Sensor within a
specified period of time after the PC1 in the Horizontal Transport Unit is
turned on, it is considered as a paper jam condition at the entry or exit of
the Tray Section.
For duplex print, the entry part of the Horizontal Transport Unit is raised
by the solenoid. The single-sided print paper is temporarily stored
between the top cover of the printer and the Horizontal Transport Unit
and waits for being switched back to the duplex unit.
