Controls
Overview
Item Explanation of operation Reference
1. Pickup block Pickup control The pickup block picks up sheets one by one from the
deck block and hands them over to the feed block.
2-7
Air assist
control
The flotation fan blows air against the paper so that the
paper is shifted slightly to lose attraction, preventing
double feeding.
2-8
Air heater
(option)
control
A left flotation fan with an air heater blows hot wind
against paper to reduce the humidity, thus facilitating
separation of coated paper.
2-9
Swing
operation
The swing operation of the shutter moves itself up and
down while a flotation fan blows air against paper. The
direction of air blow against paper changes up or down
repeatedly, vibrating the paper for easier separation.
2-10
Paper surface
detection When the paper surface sensor detects the top surface
of paper with the upward movement of the lifter, the
lifter stops to keep the top surface of paper at the
pickup position.
2-10
Paper
presence/
absence
detection
control When the paper runs out and the paper detecting lever
of the pickup roller assembly moves past the deck
paper presence/absence sensor, the host machine
indicates the absence of paper on its control panel.
2-11
2. Feed block Feed control Paper fed from each deck is fed to the host machine
via the vertical and horizontal paths. 2-11
Double feed
detection
control
(Option) The double feeding sensor mounted on the horizontal
path emits ultrasonic sounds like burst and judges
whether double feeding occurs or not according to the
echo level.

3.
Compartment Deck open/
close control
When the deck open switch is pressed, the lifter starts
to descend. When the lifter HP sensor detects the
home position of the lifter, the lifter stops and the deck
open/close solenoid turns on to unlock the deck.
2-14
Lifter control The lifter is connected to the drive shaft via a cable,
and is moved up or down by the deck lifter motor.
2-15
Lifter error
detection
control
When the lifter moves up or down, three types of error
detection are performed, i.e., upper limit detection
to prevent excessive ascension of lifter, lower limit
detection to prevent excessive descension of lifter, and
foreign object detection to stop the lifter to prevent the
equipment from being damaged.
2-16
Cassette
heater control
(Option) The cassette heater makes the temperature inside the
deck suitable to reduce the humidity, thus facilitating
separation of paper.
2-17
Remaining
paper level
detection
control The level of the paper remaining in the deck is detected
by counting the lifter motor pulses that represent
the distance of movement of paper from the lifter HP
sensor to the paper surface sensor. 2-17
Paper size
switching
control
To switch between paper sizes, move the side and
rear guide plates to suit the paper side and enter the
appropriate paper size in the user mode.
2-18
4. Power
supply block
Power supply The power supply block supplies DC power to the
motors, solenoids, clutches, and other components.
2-21
5. Others Jam detection The signal from the sensor is read at the check timing
recorded in the host machine to judge whether paper is
present and fed normally.
