4.5.2 TRAY 2
The tray 2 lift motor [A] controls the vertical position of tray 2 [B] through gears and
timing belts [C].
The paper height detection is the same as for tray 1.
When the tray lowers during printing, the tray is judged to be overflowing when the
tray 2 overflow sensor 1 [D] is off and the tray 2 overflow sensor-2 [F] is on (see
‘Normal Mode’ in the above diagram).
In the multi-tray staple mode (selected by the service technician), the machine
detects that the paper stack height has exceeded the overflow limit when the
actuator [E] enters the tray 2 overflow 1 sensor [D].
The lower limit sensor [G] for tray 2 detects when tray 2 is at its lowest limit and
stops the tray 2 lift motor.
The function of the tray 2 upper limit switch [H] is the same as for tray 1.
