(NOTE 1) On the document sensor PCB are these sensors
- Document front sensor
- Document rear sensor
On the harness support is a document tray open sensor.
(NOTE 2) On the scanner base is a CCD HP sensor.
(NOTE 3) On the heat-fixing unit are a jam sensor and heater thermistor.
(NOTE 4) The main PCB monitors the internal resistance of the in-casing
temperature sensor (thermistor) attached to the main chassis.
(NOTE 5) On the paper ejection sensor PCB is the paper ejection sensor
(photosensor).
(NOTE 6) On the engine PCB are these photosensors:
- Registration sensor
- Manual insertion sensor
- Cassette sensor
(NOTE 7) On the toner sensor (light-receiver) PCB is a light-sensitive
transistor.
(NOTE 8) On the toner sensor (LED) PCB are an LED and cover sensor
(photosensor).
