Drive Release Solenoid - Ricoh B121 Service Manual

Drive Release Solenoid

The fusing drive release solenoid [E] is on the rear
end of the gear holder. When the solenoid is off,
the spring [D] pulls the gear holder, and the drive
gear engages with the fusing unit drive gear. When
the solenoid is on, it pulls the top end of the gear
holder to the right, and the gear holder turns clockwise. As a result, the drive gear
is released from the fusing unit drive gear.
The release solenoid comes on when you turn on the main switch if the fusing
temperature is 18°C or higher (
the drive gear from the fusing unit drive gear. The fusing lamps heat the hot roller
[L] more effectively since the heat is not conducted to the pressure roller [K]. When
the hot roller becomes hot enough, the release solenoid turns off, letting the drive
gear engage with the fusing unit drive gear.
