Item Explanation of operation Refer
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.
“Pickup Control”
on page 23
Air assist control The Deck Flotation Fan blows air against the paper so that the pa-
per is shifted slightly to lose attraction, preventing double feeding.
The Deck Flotation Fan 1 with an air heater blows hot wind against
paper to reduce the humidity, thus facilitating separation of paper.

trol” on page

Swing operation The swing operation of the shutter moves itself up and down while
a Deck Flotation Fan blows air against paper. The direction of air
blow against paper changes up or down repeatedly, vibrating the
paper for easier separation.

tion” on page

Paper surface detection con-
trol
When the Deck 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.

Detection Con-
trol” on page

Paper presence/ absence de-
tection 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.

Absence Detec-
tion Control” on
page 27
2. Feed Block Feed control Paper fed from each deck is fed to the host machine. “Feed Control” on
page 27
Double feed detection control The double feeding sensor mounted on the upper and lower of
Feed section emits ultrasonic sounds like burst and judges whether
double feeding occurs or not according to the echo level.

trol” on page

3. Compart-
ment Block
Deck opening/ closing control When the Deck Open Switch is pressed, the Lifter starts to de-
scend. When the Deck Relay Paper Sensor detects the paper sup-
ply stop position of the Lifter, the Lifter stops and the Deck Open/
Close Solenoid turns on to unlock the deck.
“Deck Opening/
Closing Control”
on page 31
Lifter control The Lifter is connected to the drive shaft via a cable, and is moved
up or down by the Deck Lifter Motor.
“Lifter Control” on
page 32
Lifter failure detection control When the Lifter moves up or down, three types of error detection
are performed, i.e., upper limit detection to prevent excessive as-
cension of lifter, lower limit detection to prevent excessive descen-
sion of lifter, and foreign object detection to stop the lifter to prevent
the equipment from being damaged.

tection Control”

Cassette heater control (JP
Model only)
The cassette heater makes the temperature inside the deck suita-
ble to reduce the humidity, thus facilitating separation of paper.
“Cassette Heater
Control (JP Model
only)” on page
36
Remaining paper level detec-
tion control
The level of the paper remaining in the deck is detected by counting
the Deck Lifter Motor pulses that represent the distance of move-
ment of paper from the Deck Relay Paper Sensor to the Deck Paper
Surface Sensor.

per Level Detec-
tion Control” on

Switching between paper
sizes
Paper size can be automatically detected by adjusting the position
of the guide plate.

tween Paper
Sizes” on page

4. Deck Control
Block
Power supply The power supply block supplies DC power to the motors, sole-
noids, and other components.
“Power Supply”
on page 41
5. Through Path
Block (Option)
Feed control Paper picked up in the Stack Bypass or the connect Deck is handed
over to the feed block.
Separately from the Paper Deck Double Feeding Detection Sensor
of the Paper Deck, the Through Path Unit comes standard with
Through Path Double Feeding Sensors, which judge whether paper
is fed one by one.
