8 HCI unit explanation ENWW
Paper feed section
Composition
Note In the following diagram, LT refers to the high capacity input (HCI).
Mechanisms
*1 Paper lifting
a Up/down plate lifting drive operation
The up/down plate is lifted with the
up/down wires. When the top cover
closes, HCI up/down motor (M100)
rotates and the up/down plate
connected to the up/down wires rises.
a Up/down plate down drive operation
The up/down plate automatically lowers
by 120 mm when the top cover is
opened.
Subsequently, it is lowered by 120 mm
each time HCI tray down drive switch
(SW100) is pressed.
*2 Remaining paper detection
The HCI is equipped with a remaining
paper detection gear which rotates
together with HCI up/down motor
(M100) driving the up/down plate.
The remaining paper detection gear has
an actuator to turn on/off HCI remaining
