Solution
In addition to checking for sensor/actuator defect by eye, also execute Input/Output Check as
necessary.
1. Check if the tray is overloaded.
If so, set the paper correctly.
2. Check the connectors of the harnesses related to load detection (lower limit sensor / paper height
middle sensor / upper limit sensor 2)
Reconnect the connectors. Turn the main power OFF and then ON.
3. Check the electrical components related to load detection (lower limit sensor / paper height middle
sensor / upper limit sensor 2)
If they are defective, replace them. Turn the main power OFF and then ON.
