No. Component Function
S67/S68
Laser Unit Temperature
Sensor A sensor pair that reads the temperature in the optics unit. The
readings are used in MUSIC processing.
S69 Toner End Sensor: M Detects toner end for magenta toner.
S70 Toner End Sensor : K Detects toner end for black toner.
S71 Toner End Sensor: Y Detects toner end for yellow toner.
S72 Toner End Sensor: C Detects toner end for cyan toner.
S73 Scanner HP Sensor Detects the home position of the scanner.
S74 Original Width Sensors
APS1 (a board) holds two original width sensors under the
exposure glass. The detection combinations of these sensors
determine the width of the original on the exposure glass
positioned for LEF.
S75
Original Length Sensors -
1
APS2 (a board) holds two original length sensors under the
exposure glass. The detection combinations of these sensors
determine the length of the original on the exposure glass
positioned for SEF.
S76 Original Length Sensor -2
APS3 (a board) holds one original length sensor under the
exposure glass. The detection combination of this sensor and
other sensors determine the length of the original on the
exposure glass positioned for SEF.
S77 Accordion Jam Sensor
Detects jams at the fusing exit by confirming that paper arrives
at the prescribed time.
S78 Fusing Exit Sensor
Detects jams at the fusing exit by confirming that paper leaves
at the prescribed time.
S79 LCT Relay Sensor Confirms whether the LCT is set correctly.
S80 Original Length Sensor 3
APS4 holds one original length sensor under the exposure
glass. The detection combination of this sensor with other
sensors determines the length of the original on the exposure
glass positioned for SEF.
S81 Encoder
Monitors the rotation of the encoder wheel in the ITB drive
motor unit.
S82 PTR Contact Sensor Detects when the PTR is lifted and lowered.
