MX-LCX2 OPERATIONAL DESCRIPTION 5 – 1
MX-LCX2 Service Manual
[5] OPERATIONAL DESCRIPTION
1. Lift operation
When the main unit is turned ON, if the tray is at the lower limit
position (lower limit sensor: LDD ON position), the lift motor is
turned ON to lift the tray.
When the paper presence/empty sensor (LPED) is turned ON
within 800 pulses of the encoder signal from start of lifting up the
tray, the lift motor is turned OFF to stop the tray, and the paper feed
solenoid is turned ON to move down the pickup roller. After that,
the lift motor is turned ON to lift the tray. The tray is stopped when
the upper limit sensor (LUD) is turned ON.
If the paper presence/empty sensor (LPED) is not turned on within
800 pulses, the paper feed solenoid is turned ON with the lift motor
ON to move down the pickup roller. The lift motor is stopped at the
upper limit sensor (LUD) ON position, and the paper feed solenoid
is turned OFF.
When the machine power is turned on, if the tray is on the paper
feed position, lifting is not performed.
When the tray is pulled out, it moves down by its own weight.
Lifting up operation (When LPED is turned ON within 800 pulses of encoder.) Lifting up operation (When LPED is not turned ON within 800 pulses of encoder.)
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 (LRFM) 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.

[8] ADJUSTMENTS
Each adjustment item in the adjustment item list is indicated with its JOB number. Perform the adjustment procedures in the sequence of Job
numbers from the smallest to the greatest.
However, there is no need to perform all the adjustment items. Perform only the necessary adjustments according to the need.
Unnecessary adjustments can be omitted. Even in this case, however, the sequence from the smallest to the greatest JOB number must be
observed.
If the above precaution should be neglected, the adjustment would not complete normally or a trouble may occur.

2. Details
ADJ 1 Print off-center adjustment
1) Execute SIM.50-10 by the key operation of the machine. Then,
the displays shown on the right side appear.
2) The print off-center adjustment value can be set for each tray.
3) Press the [↓] key on the touch panel to select “G:50:LCC”.
4) Then, enter your desired adjustment value with the [10] key.
(Default: 50 Adjustment range: from 1 to 99)
* If the adjustment value is decreased by 1, the main scanning
print position is shifted to the front side by 0.1mm.
* If the adjustment value is increased by 1, the main scanning
print position is shifted to the rear side by 0.1mm.
5) When the [EXECUTE] button is pressed, the [EXECUTE] but-
ton is highlighted, currently set value is saved into the
EEPROM and the RAM, and printing for adjustment pattern
image is started. After printing is finished, the [EXECUTE] but-
ton returns to the normal display status.
6) Check the adjustment pattern image position.
Measure the dimensions of the void area in the adjustment
pattern front and rear frame directions, and ensure that they
satisfy the conditions shown below.
If condition of A - B = 0±3.0mm is satisfied, no adjustment is
necessary.
If it does not satisfy the condition above, execute the proce-
dures shown below.
7) Change the adjustment value. Repeat the steps from 4) to 6)
until the condition described in the step 6) is satisfied.
8) After the adjustment is finished, escape from the simulation
mode with the reset key.

MX-LCX2 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.

Item Display items and
details Descriptions Setup range Default Writing Remarks
A DEN-C Print lead edge adjustment 1 to 99 30 Yes
Adjustment value for matching to the print lead
edge for printer.
As the adjustment value of this item is decreased
by 1, the print start position against the paper
feeding direction is moved to the leading edge side
by 0.1mm.
BDEN-B Sub scanning direction print area
adjustment 1 to 99 20 Yes
Amount of void to be created at the trailing edge of
paper. As the adjustment value of the item B(DEN-
B) is decreased by 1, the sub scanning print range
adjustment value is decreased by 0.1mm.
C FRONT/REAR FRONT/REAR void amount
adjustment 1 to 99 20 Yes
Amount of void to be created at the right and left
