Spec-25
No. Component Function
S12
Vertical Transport Sensor -
Tray 3
Detects the leading edge and trailing edge of each
sheet fed from tray 3 and signals a jam if the edges
do not pass at the prescribed time.
S13 Paper End Sensor - Tray 3
Receives light reflected from the paper until the last
sheet is fed from tray 3 (bottom tray), then signals
paper end.
S14 Lift Sensor - Tray 3
Detects when the pick up roller (pushed up by the
top of the paper stack in the right side of the
tandem tray) has reached the correct height for
paper feed and then switches off the tray 3 (bottom
tray) lift motor.
S15
Bottom
Temperature/Humidity
Sensor
Near the waste toner bottle. Detects ambient
temperature and humidity and then this output is
used to control the amount of current applied to the
paper transfer roller and ITB when the image is
transferred to paper. Also used to correct the fusing
temperature, and to extend the fusing unit idle time
at low room temperatures.
S16
Waste Toner Bottle Set
Sensor
Detects the position of the waste toner bottle and
confirms whether it is set correctly.
S17
Waste Toner Bottle Near-Full
Sensor
When the level of the waste toner rises high enough
to move the actuator of this sensor out of its normal
position, the sensor signals the machine that the
waste toner bottle is nearly full.
S18
Waste Toner Bottle Full
Sensor
Signals an alert when the waste toner bottle is full.
S19 Paper Feed Sensor - Tray 1
Detects the leading edge of each sheet of paper
from the pick–up roller of tray 1 (tandem tray) and
switches off the pick–up roller solenoid so the pick–
up roller lifts.
S20
Vertical Transport Sensor -
Tray 1
Detects the leading edge and trailing edge of each
sheet fed from tray 1, 2, and 3 and signals a jam if
the edges do not pass at the prescribed time.
S21 Paper End Sensor - Tray 1 Detects when the last sheet is fed from tray 1.
S22 Lift Sensor - Tray 1
Detects when the pick up roller (pushed up by the
top of the paper stack in the right side of the
tandem tray) has reached the correct height for
paper feed and then switches off the tray 1 (tandem
tray) lift motor.
S23
Paper Near End Sensor -
Tray 2
Detects the near end condition for tray 2 (middle
tray, a universal cassette).
S24
Paper Near End Sensor -
Tray 3
Detects the near end condition for tray 3 (middle
tray, a universal cassette).
S25
Front Side Fence Open
Sensor
Detects the actuator on the front side fence after it
has reached the open position in the tandem tray.
S26
Front Side Fence Closed
Sensor
Detects the actuator on the front side fence after it
has reached the closed position in the tandem tray.
S27
Rear Side Fence Open
Sensor
Detects the actuator on the rear side fence after it
has reached the open position in the tandem tray.
S28
Rear Side Fence Closed
Sensor
Detects the actuator on the rear side fence after it
has reached the closed position in the tandem tray.
S29 Right Tray Down Sensor
Detects the bottom plate of the right tray and
switches off the tray 1 lift motor and stops the
bottom plate.
