No. Component Function
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.
