S9 Paper End Sensor: Tray 2
Receives light reflected from the paper until the
last sheet is fed from tray 2 (middle tray), then
signals paper end.
S10 Lift Sensor: Tray 2
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 2
(middle tray) lift motor.
S11 Paper Feed Sensor: Tray 3
Detects the leading edge of each sheet of paper
from the pick–up roller of tray 3 (bottom tray) and
switches off the pick–up roller solenoid so the
pick–up roller lifts.
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.
