Stapler unit motor (in the stapler unit assembly)
—
A DC motor to activate the stapler unit assembly for stapling
—
Clockwise rotation of this motor enables stapling, while counterclockwise rotation returns the stapler
unit assembly.
Sensor (stapler carriage HP)
Upper media bin
Operation
The upper media bin contains the sensor (upper media bin full) to detect the media stack volume in the upper
media bin.
Once the sensor detects a full stack (500 sheets) in the upper media bin, ejection of media to the upper media
bin is inhibited until a full stack is reset.
Functions of upper media bin sensors
•
Sensor (upper media exit)
—
A photo-interrupter sensor that detects that media has come to the upper media exit roll assembly top
at the exit of the upper media bin
—
When media reaches the upper media exit roll assembly top, the actuator leaves the sensing area,
which turns the sensor to high (+5 V dc).
•
Sensor (upper media bin full)
—
A photo-reflective sensor that detects the media stack volume in the upper media bin
—
It turns high (+5 V dc) when it detects a full stack.
