1. Operation
a. Operation when copying
Paper feed for the first sheet starts a specified time
after the start button is turned ON. The paper feed
operation starts when the M401 and SD401 turn ON.
The M401 turns OFF a specified time after the PS401
(paper feed detect) detects the leading edge of the
page. SD401 turns OFF a specified time after turning
ON.
Paper feed for the second and subsequent sheets
starts a specified time after the SD401 for the
previouspage turns ON.
When the paper tray is empty, PS402 (no paper

MAIN BODY
The PFUDB (PFU) (PFU drive board (PFU)) is fitted with a
series of tact switches for detecting paper size. This
informs the main body of the paper size in each tray.
1. Operation
Each tray has a series of actuators that are operated
by the paper guides. When each tray is inserted,
these projections turn the tact switches on the
PFUDB (PFU) OFF and ON. The PFUDB (PFU)
determines the paper size of the PFU from the ON/
OFF combinations.

The paper tray (LCT) is suspended using four Up/
Down drive wires (A, B, C and D).
When paper is loaded into the tray, the tray moves
down due to the weight of the paper. The weight of
the paper is balanced by the tension of the drive
auxiliary spring.
When the paper tray (LCT) is inserted, the up/down
motor (M403) rotates, winding the wires on the drive
reel and raising the tray.
When the paper tray is withdrawn from the frame, the
tray drive section and the coupling separate from
each other. This causes the tray to move down to the
position where the paper is balanced by the tension
of the drive auxiliary spring.

Paper is fed by transmitting the M401 (paper feed) driving
force to the paper feed roller and feed roller through
SD402 (paper feed (LCT)).
M401 is driven by the PFUDB (PFU drive board (PFU))
and controlled by the paper feed drive board PFUDB
(PFU) in the main body.
SD402 is driven by the PFUDB (PFU drive board (LCT))
and controlled by the PFUDB (PFU).
1. Operation
a. Initial operation when the power is switched ON
(1) When the power is switched ON, M401 goes ON for the
specified period.
Reason: This is to prevent the paper from being fed from
all of the paper trays at the same time when the
Start button is pressed, as a result of the the
ratchet claw of SD402 being disengaged due to
an impact when the machine was being
transported.
b. Operation when copying
Paper feed for the first sheet starts a specified time
after the start button is turned ON. The paper feed
operation starts when the M401 and SD402 turn ON.
The M401 turns OFF a specified time after the PS401
(paper feed detect) detects the leading edge of the
page. SD402 turns OFF a specified time after turning
ON.
Paper feed for the second and subsequent sheets
starts specified time after the SD402 for the previous
page turns ON.
When the paper tray is empty, PS404 (no paper
detect (LCT)) changes to a high signal (L), to inform
the PFUDB (PFU) in the main body that there is no
paper in the tray.

The paper tray is raised when the M403 (up/down (LCT))
driving force is transmitted to the paper tray through the
up/down drive wires (four for each tray).
The M403 is driven by the PFUDB (LCT) (PFU detection
board (LCT)) and controlled by the PFUDB (PFU) (PFU
drive board (PFU)).
1. Operation
When the SW405 (LCT tray insertion detection) turns
ON, the M403 turns ON and raises the tray.
After the tray is raised, the PS405 (upper limit detect
(LCT)) detects the upper limit of the paper in the tray.
The M403 turns OFF and the tray stops.
When paper is fed the PS405 turns OFF and the tray
is raised when the M402 (up/down) turns ON again.
The paper tray is lowered mechanically.
