5. MECHANICAL OPERATION
28 February 1989
5.1 DRIVE MECHANISM
A reversible ac motor [A] drives the LCT’s bottom plate up and down.
The motor’s drive is transmitted directly to the tray drive shaft [B] via a worm
gear and worm wheel. The tray wires [C] have braces on them; these braces
hold the ends of the two lift rods which support the tray bottom plate. The
braces on the wires raise the lift rods [D] and the tray bottom plate when the
pulley turns counterclockwise, and they lower them when the pulley turns
clockwise.
11-5
28 February 1989
5.2 PICK-UP ROLLER MECHANISM
The pick-up roller [A] is driven by a drive gear [B] to initialize paper feed from
the LCT.
The paper end sensor [C] and the upper limit sensor [D] are incorporated in
the LCT not the copier. The paper end sensor is used to detect paper end
and the upper limit sensor detects when the tray has reached its upper limit
when the tray is being raised.
11-6
5.3 PAPER SIZE DETECTION
28 February 1989
The paper size dial controls side post positioning and paper size detection.
When the paper size dial [A] is rotated, the cam groove [B] moves the size
lever [C], which repositions the guide posts [D]. When the dial reaches a
standard paper size, one of the actuator plates [E] enters the paper size sensor [F]. At the same time, the pin [G] on the leaf spring [H] drops into a notch
on the inside rim of the dial and the positioning switch [I] deactuates.
When the positioning switch opens, the scan signal is applied to the LCT
paper size sensor. The paper size sensor then reads the pattern of the ac-
tuator plate and sends paper size data to the copier’s CPU.
When the paper size dial is positioned at a non-standard paper size, the
positioning switch is actuated (closed). In this case, the LCT cannot be used;
the Load Paper indicator lights and no paper size is displayed on the operation panel. This prevents the skewing that would occur if the guide posts were
not at the correct position.
11-7
28 February 1989
6. ELECTRICAL OPERATION
6.1 DOWN OPERATION
The bottom plate moves down only when the Down key is pressed or paper
end occurs. When the Down key is pressed, the flip-flop changes state (all
outputs change from LOW to HIGH or vice versa). Then, three things happen
simultaneously: (1) The gate circuit turns off, preventing size data from being
sent to the copier; (2) The timer circuit turns on, causing the LED in the down
key to blink; and (3) SSR1 turns on, energizing the drive motor to move the
tray down.
The down sensor is actuated when the bottom plate is fully lowered. This
causes the flip-flop to change back to its original state, which turns off SSR1
and resets the timer circuit. The LED in the Down key stays continuously on.
6.2 UP OPERATION
Opening and closing the upper or side LCT cover while the bottom plate is in
the down position starts the up operation. This causes the gate circuit to send
paper size data to the copier. At the same time the cover safety switch changes the state of the flip-flop and the flip-flop energizes SSR2, which turns on
the drive motor to move the tray up. The drive motor stays on until the paper
pushes up the pick-up roller. The actuator on the pick-up roller bracket then
moves out of the upper limit sensor; this again changes the flip-flop’s state
and the motor stops.
The cover safety switch prevents operation if the cover is open by cutting off
the ac 100 volt line.
