Bottom plate
The force pushing up the bottom plate is transmitted by the driving force of the motor on the media feed unit
assembly. The bottom plate is pushed up by the rotation of the lift up shaft, which causes the supplied media to
come in contact with the pick roll.
Tray 2, 3, 4 media tray assembly
3TM media feed units
Media feed unit assembly
Since the tray 2, tray 3, and tray 4 are functionally equivalent in terms of the switch (media size), sensor (media
out), sensor (media level) and sensor (pre-feed), only the components of one tray are described here.
The media feed unit assembly is a mechanical unit supplying media from the media tray assembly to the printer.
The driving force from the media feed lift motor on the media feed unit assembly is transmitted to the three roll
assemblies to feed media.
When the pick roll picks up sheets of media and the remaining media decreases, the media level actuator of the
sensor (media level) lowers accordingly.
Media feed lift motor
The media feed lift motor is activated to feed media and to lift the bottom plate. While feeding media, it rotates
forward to drive the pick roll. When lifting the bottom plate, it rotates in reverse to drive the tray module gears to
turn the lift up shaft.
Switch (media size)
The switch (media size) switches the setting of the size of media supplied from each media tray assembly. A
signal indicating the set size is transmitted as a voltage to the printer engine card assembly.
Sensor (media out)
If there is no media in the media tray assembly, the media out actuator lowers and the flag of the media out
actuator that has stayed in the sensor (media out) sensing area leaves there. Thus, the light of the sensor is
transmitted. When the sensing area is blocked (media is present), the signal turns off.
