No. Component Function
S30 Paper Near End Sensor -
Tray 1 Signals 10% paper remaining when the actuator on
the right rail of the right tray in the tandem tray
passes.
S31 Paper Height Sensor 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.
S32 Paper Height Sensor
Signals 30% paper remaining when the actuator on
the left rail of the right tray in the tandem tray
passes.
S33 Paper Height Sensor 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.
S34 Right Tray Paper Sensor
Detects paper in the right side of the tandem paper
tray.
S35 Rear Fence HP Sensor Detects the actuator on the rear fence in the
tandem tray and switches off the rear fence motor.
S36 Rear Fence Return Sensor Detects the actuator on the rear fence in the
tandem tray and reverses the rear fence motor.
S37 Left Tray Paper Sensor Detects the presence of paper in the left tray of the
tandem tray.
S38 Heating Roller Temperature
Sensor Monitors the surface temperature of the heating
roller and breaks the circuits to the fusing lamps if
the heating roller overheats.
S39 Waste Toner Lock Sensor
Signals an alert if the waste toner collection coil
locks and stops rotating.
S40 Duplex Transport Sensor 1 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.
S41 Duplex Inverter Sensor 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.
S42 Duplex Entrance Sensor Detects paper jams at the entrance of the duplex
unit.
S43 Duplex Transport Sensor 3
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.
S44 Duplex Transport Sensor 2
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.
S45 Duplex Jogger HP Sensor At power on, detects the actuators on the jogger
fences of the duplex unit, switches off the duplex
jogger motor and stops the fences at their home
positions.
