2.5.6 500 PAPER EXIT & FACE UP TRAY
The 500 Paper Exit is a component designed to eject printed paper from the printer.
In addition to Face Down paper ejection, the 500 Paper Exit allows ejection of Face Up
paper to the Face Up Tray (tray mounted on the printer rear) and ejection to the Option
OCT.
MOTOR ASSY EXIT
This motor drives the ROLL EXIT that transports paper to the corresponding exit tray.
When the optional Duplex is installed, this motor also has the function to turn over and
insert the paper to the Duplex.
ROLL EXIT
This roll transports the printed paper, which is fed from the Fuser, to the Face Down
paper exit tray.
ROLL FU
This roll transports the printed paper, which is fed from the Fuser, to the Face Up paper
exit tray.
SENSOR FACE UP OPEN
This sensor detects that Face Up print is selected. When the LEVER GATE FU is
raised, the signal is detected by the Actuator mounted on the synchronizing GATE FU,
and the printer is put in the Face Up print mode.
SENSOR FULL STACK
This sensor detects that the 500 Exit Face Down paper exit tray is full by means of the
ACTUATOR FULL STACK.
GATE FU
This gate operates in synchronization with the LEVER GATE FU to change the paper
transport path. When the LEVER GATE FU is raised, GATE FU intercepts the normal
paper exit path, switching the exit direction to the Face Up paper exit tray.
GATE OCT EXIT
This gate operates in synchronization with the LINK GATE OCT to change the paper
transport path.
When the SOLENOID ASSY GATE installed on the optional OCT operates, the
GATE OCT EXIT intercepts the normal paper exit path by means of the LINK GATE
OCT pushed down by the spindle of the SOLENOID ASSY GATE and switches the
exit direction to the OCT paper exit tray.
