Lower Feeder Unit Theory of Operation Operations

II Composition/Operation
3.1.3 Paper separation mechanism
• A Separation Roller provided with a torque limiter is used to prevent double feeding of
paper.
3.1.4 Paper detection mechanism
• The Lower Feeder Paper Feed Sensor (PC3 PF) detects the paper fed in by the Feed
Roller.
• When two Lower Feeder Units are installed, the sensor detects the paper fed off from
Tray 3.
• When the Lower Feeder Paper Feed Sensor actuator unblocks the Lower Feeder Paper
Feed Sensor (PC3 PF), the machine considers that the paper has reached the sensor
position.
