Operating Principles Description of Mechanisms 88
2.2.7.3 Paper Cassette Empty Sensor
The Paper Cassette Empty sensor is mounted on the control board in the Lower
Cassette and it detects “paper cassette empty”.
(See “Figure 2-26”)
When there is paper, the actuator is lifted so that the light to the sensor is
intercepted.
When the cassette is empty of paper, the actuator falls into the hole in the paper
lifting plate so that the light to the sensor is transmitted.
2.2.7.4 Cassette Type Sensor
The Lower Cassette is equipped with the cassette type sensor switch having a lever.
(See “Figure 2-27”)
When the cassette for a paper size is inserted, the switch presser on the right side
of the cassette pushes the lever according to the paper size and it turns the cassette
type sensor ON.
These triple switches enable the printer to distinguish the cassette types (paper
sizes) by ON/OFF combinations of the switches.
Table 2-8 below indicates the status of the Cassette Type Sensor Switch for each
cassette type:
