MX-CFX1 ELECTRICAL SECTION 11 – 5
R39 is a current limiting resistor for the LED. R34 is a load resistor
for the sensor.
3) Reverse Unit Open/Closed Sensor (HYK_SEN)
HYK_SEN uses the photointerrupter integrated with an LED and a
phototransistor.
The sensor detects state of the reverse unit with the lever actuator
interrupting the light path of the photointerrupter.
The signal is transmitted to the CPU (IC6-Pin108) through the
noise filters (R21,C7).
The signal input to the CPU follows the logic: "L" when the reverse
unit is open, "H" when closed.
R37 is a current limiting resistor for the LED. R32 is a load resistor
for the sensor.
4) Set Sensor (S_SEN)
S_SEN uses the photointerrupter integrated with an LED and a
phototransistor.
The sensor detects the main unit with the lever actuator interrupting
the light path.
The signal is transmitted to the CPU (IC6-Pin2) through the noise
filters (R56,C16).
The signal input to the CPU follows the logic: "H" when the inserter
is connected to the main unit, "L" when not connected.
R59 is a current limiting resistor for the LED. R58 is a load resistor
for the sensor.
5) Empty Sensor (EMP_SEN)
EMP_SEN uses the photointerrupter including the LED and the
phototransistor in one unit.
The sensor detects a sheet with the lever actuator interrupting the
light path.
The signal is transmitted to the CPU (IC6-Pin31) through the noise
filters (R7,C4).
The signal input to the CPU is the following logic: the signal is "H"
when a sheet is detected, "L" when not detected.
R12 is the current limiting resistor for the LED. R11 is the load
resistor for the sensor.
6)
Registration Sensor (REG_SEN)
REG_SEN uses the photointerrupter integrated with an LED and a
phototransistor.
The sensor detects a sheet with the lever actuator interrupting the
light path.
The signal is transmitted to the CPU (IC6-Pin32) through the noise
filters (R14,C5).
The signal input to the CPU follows the logic: "L" when a sheet is
detected, "H" when not detected.
R17 is a current limiting resistor for the LED. R16 is a load resistor
for the sensor.
7)
Timing Sensor (TIM_SEN)
TIM_SEN uses the photointerrupter integrated with an LED and a
phototransistor.
The sensor detects a sheet with the lever actuator interrupting the
light path.
The signal is transmitted to the CPU (IC6-Pin33) through the noise
filters (R19,C6).
The signal input to the CPU follows the logic: "L" when a sheet is
detected, "H" when not detected.
R18 is a current limiting resistor for the LED. R31 is a load resistor
for the sensor.
8) Paper Width Detection Potentiometer (T_VR)
T_VR is a potentiometer.
The paper width is detected using the output voltage, which may
vary depending on the potentiometer's knob position.
The signal is transmitted to the CPU (IC6-Pin112) through the
noise filters (R48,C12).
