Component Function
Signals 10% paper remaining when the actuator on
the right rail of the right tray in the tandem tray
passes.
Signals 100% paper remaining until activated.
Signals 50% paper remaining when the actuator on
the left rail of the right tray in the tandem tray
passes.
Signals 30% paper remaining when the actuator on
the left rail of the right tray in the tandem tray
passes.
When near end sensor 1 on right rail of the right
tray of the tandem tray is actuated, and paper
height sensor 3 has detected the passing of the
actuator on the left rail, then the near end sensor
signals 10% paper remaining.
Detects paper in the right side of the tandem paper
tray.
Detects the actuator on the rear fence in the
tandem tray and switches off the rear fence motor.
Detects the actuator on the rear fence in the
tandem tray and reverses the rear fence motor.
Detects the presence of paper in the left tray of the
tandem tray.
Monitors the surface temperature of the heating
roller and breaks the circuits to the fusing lamps if
the heating roller overheats.
Signals an alert if the waste toner collection coil
locks and stops rotating.
The feeler of this sensor detects the leading edge
and trailing edge of each sheet as it passes from
the jogger unit above and into the horizontal feed
path of the duplex unit below. Signals a jam if the
paper does not arrive at or reach the sensor
location at the prescribed time.
1) Detects the leading edge of the paper at the
inverter exit roller, signals to switch off the duplex
transport clutch and retracts the reverse trigger
roller, and 2) Controls the operation of the duplex
transport clutch.
Detects paper jams at the entrance of the duplex
unit.
Detects the leading edge and trailing edge of each
sheet as it passes from the jogger unit above
through the horizontal feed path of the duplex unit
below. Signals a jam if the paper does not arrive at
or reach the sensor location at the prescribed time.
Detects the leading edge and trailing edge of each
sheets as it passes from the jogger unit above and
into the horizontal feed path of the duplex unit
below. Signals a jam if the paper does not arrive at
or reach the sensor location at the prescribed time.
At power on, detects the actuators on the jogger
fences of the duplex unit, switches off the jogger
motor and stops the fences at their home positions.
