MX-LCX3 OPERATIONAL DESCRIPTION 5 – 1
MX-LCX3 Service Manual
[5] OPERATIONAL DESCRIPTION
1. Lift operation
A. Lifting by insertion of the tray
When insertion of the tray is detected, the tray is locked by the tray
lock solenoid so that the tray cannot be pulled out.
When tray lock is settled by turning ON the tray lock sensor (LTLD),
the lift motor is turned ON to lift the tray.
When the tray is lifted, the tray LED blinks and stops at the paper
feed position (upper limit) by turning ON the upper limit sensor
(LUD).
When the tray stops at the paper feed position (upper limit), the tray
LED turns on.
When the paper empty sensor (LPED) turns ON within 1097 pulses
of the encoder signal from start of the tray lifting, the lift motor is
turned OFF to stop the tray, and the paper feed solenoid (LPFS) is
turned ON to lower the pick roller.
After that, the lift motor is turned ON again to lift the tray and stop it
at the upper limit sensor (LUD) ON position.
When the paper empty sensor (LPED) does not turn ON within
1097 pulses, the paper feed solenoid (LPFS) is turned ON with the
lift motor ON to lower the pick roller. The lift motor is stopped at the
upper limit sensor (LUD) ON position and the paper feed solenoid
is turned OFF.
Lifting (When LPED turns ON within 1097 pulses during lifting)
Lifting (When LPED does not turn ON within 1097 pulses dur-
ing lifting)
B. Lowering operation by paper empty detection
or pressing the tray SW
When the paper empty sensor (LPED) turns OFF with the tray at
the paper feed position (upper limit) or when the tray SW (LTLSW)
is pressed, the tray is lowered by 542 pulses of the encoder signal
and stopped at the paper supply position.
When the lower limit sensor (LDD) turns ON before lowering the
tray by 542 pulses of the encoder signal, the lift motor is turned
OFF to stop the tray.
When the tray is moving down, the tray LED blinks. When the tray
is stopped at the paper supply position, the tray LED turns OFF.
When the tray is stopped at the paper supply position, the tray lock
solenoid releases the lock so that the tray can be pulled out.
When the tray is lowered with the paper empty sensor (LPED) OFF,
the tray remains at the paper supply position and the tray lock is
kept released.
When the tray is lowered by pressing the tray SW (LTLSW), if the
tray is not pulled out from the paper supply position for 90sec, the
tray lock solenoid locks the tray. When the tray is locked securely,
the lift motor is turned ON to lift the tray.
When the tray is lifting, the tray LED blinks. When the upper limit
sensor (LUD) is turned ON, the tray stops at the paper feed position
(upper limit).
When the tray stop at the paper feed position (upper limit), the tray
LED turns ON.

C. Lowering operation by paper supply
If the tray is pulled out when it is at the paper supply position, the
tray lock solenoid keep the lock released.
When the tray is pulled out, the tray LED turns OFF.
When the paper front surface sensor (LPUD) is turned ON for 2sec
while the tray is pulled out, the lift motor is turned ON to lower the
tray.
When the paper front surface sensor (LPUD) is turned OFF while
the tray is lowered, the lift motor is turned OFF to stop the tray.
When the lower limit sensor (LDD) is turned ON while the tray is
lowered, the lift motor is turned OFF to stop the tray regardless of
the state of the paper front surface sensor (LPUD).
Lowering operation (when paper is supplied or when the paper
front surface sensor is turned ON)
Lowering operation (when paper is supplied or when the lower
limit sensor is turned ON)
2. Paper feed operation
When the tray is stationary at the paper feed position (upper limit
sensor: LUD ON position) and there is paper on the tray, paper
feed operation can be performed.
Paper feed operation is performed by the transport motor (LPFM),
the transport clutch (LTRC), the paper feed clutch (LPFC), and the
paper feed solenoid (LPFS) at the following timing.
When the transport clutch (LTRC) is turned ON with the transport
motor (LPFM) ON (rotating), the transport roller rotates. When the
paper feed clutch (LPFC) is turned on under this state, the paper
feed roller and the take-up roller rotate. When the paper feed sole-
noid (LPFS) is turned ON, the take-up roller is pushed down to
press paper.

MX-LCX3 ADJUSTMENTS 8 – 4
2-B Print lead edge adjustment
1) Execute SIM.50-5 by the key operation of the machine. Then,
the displays shown on the right side appear.
2) Press the [↓] key on the touch panel to select “E:PAPER”.
3) Then, enter the adjustment value 6 with the [10] key, and press
the [OK] button.
(Adjustment value 6: LCC)
4) When the [EXECUTE] button is pressed, the [EXECUTE] but-
ton is highlighted, and printing for adjustment pattern image is
started with the currently set value. After printing is finished,
the [EXECUTE] button returns to the normal display status.
5) Check the adjustment pattern image position.
Measure the dimensions of the void area in the adjustment
pattern right and left frame directions, and ensure that they sat-
isfy the conditions shown below.
If condition of A=4.0±2.0mm, B=4.0±2.0mm is satisfied, no
adjustment is necessary.
If it does not satisfy the condition above, execute the proce-
dures shown below.
6) Change the adjustment values of the adjustment items
A(DEN-C) and B(DEN-B).
* As the adjustment value of the item A(DEN-C) is decreased
by 1, the print start position is moved to the lead edge side of
paper against the paper feed direction by 0.1mm.
* As the adjustment value of the item B(DEN-B) is decreased
by 1, the print range is increased to the trailing edge side of
paper against the paper feed direction by 0.1mm.
7) Repeat the steps from 4) to 6) until the condition shown in the
step 5) is satisfied.
8) After the adjustment is finished, escape from the simulation
mode with the reset key.
