2.2.4.1 MSI (Multi Sheet Inserter)
MAIN FUNCTIONS
 GUIDE SIDE L/GUIDE ASSY SIDE R
GUIDE SIDE L and GUIDE ASSY SIDE R move crossways of the paper feed
direction, and true up the left and right edges of sheets of paper.
 SOLENOID PICK UP
The SOLENOID PICK UP controls rotation of GEAR PICK UP. When the
Solenoid is excited, GEAR PICK UP is unlocked, and ROLL MSI rotates by drive
of the MOTOR-PH.
 PLATE BOTTOM ASSY MSI
PLATE BOTTOM ASSY MSI is normally pressed down by the Cam attached to
the shaft. During paper feed, the shaft rotates, releasing the clamping action of the
cam, and the paper is pressed against the ROLL MSI by spring pressure.
 ROLL MSI
Paper that is pressed down by the PLATE BOTTOM ASSY MSI is fed by the
frictional force of the ROLL MSI.
 SENSOR PAPER EMPTY
The SENSOR PAPER EMPTY detects the presence of paper. When the printer
runs out paper, the actuator of the sensor comes down by its own weight and
shields the sensor, and the no paper state is detected. (No paper state : Shielding
the sensor)
