8)

Press [EXECUTE] key.

The adjustment pattern is printed.

9)

Check that the adjustment pattern image is printed in the cor-
rect position.

Perform the procedures 7 thru 9 until the adjustment pattern
comes virtually at the center.

10) When the adjustment pattern comes virtually to the center by

the adjustment, perform the fine adjustment with the simula-
tion. (90cpm machine only)

Enter the adjustment value, and press [EXECUTE] button.

The adjustment pattern is printed.

When the adjustment value is increased, the image is shifted
to the front frame side. When the adjustment value is 
decreased, the image is shifted to the rear frame side. 

A change in the adjustment value by 1 corresponds to a shift
by about 0.1mm.

11) Check that the adjustment pattern image is printed in the cor-

rect position.

Measure the void area sizes of the adjustment pattern on the
front edge and the rear edge, and check that the sizes satisfy
all the following conditions.

RV: REAR VOID AREA
FV: FRONT VOID AREA
RV +  FV 

 5.0mm

RV = 2.5mm or less   
FV = 2.5mm or less

Perform the procedures 10 and 11 until the above conditions
are satisfied. 

 

This adjustment is needed in the following situations:

* When the paper feed tray section is replaced.

* When the paper feed tray section is disassembled.

1)

Enter the Sim. 50-10 mode.

2)

Select a paper feed source for an adjustment target with the
scroll button.

3)

Set A4 (11 X 8.5) or A3 (11 X 17) paper on the paper feed tray
selected in the procedure 2.

4)

Enter 50 as default value of off-center adjustment, and press
[OK] button.

6)

Check that the adjustment pattern image is printed in the cor-
rect position.

When the adjustment pattern is printed virtually at the center,
go to the procedure 10). 

If not, go to the procedure 7). 

7)

Shift the paper feed tray paper guide position and the paper
feed tray base plate back and forth to adjust the off-center. 

Adjust so that the adjustment pattern is virtually at the center.

a)

In the case of MX-LC13N

Since the off-center adjustment has been made at ship-
ping, there is normally no need to djust. If the center is
shifted, however, adjust with the simulation. If the shift is
not recovered, perform the following steps to adjust.

1) Manually pull out the cassette.

Push the shaft at the bottom of the front cabinet to
release the lock, and pull out the cassette.

When shifting the line of printing from the center of the
paper in the direction A of arrow as shown below:

1) Loosen the blue off-center adjustment screws (each

2pcs.), and move the side plate by the dimension
shifted in the direction A (R side), and tighten the blue
screws.

MEMO: The side cabinet front moves in conjunction

with the side cabinet rear.

2) Set a sheet of paper on the paper feed base tray.

Check that the front regulation plate is at the marked
center, and push it in contact with the front regulation
plate. Loosen the blue screw of the rear regulation
plate.

3) Use the mark of the rear regulation plate, and fix the

blue screw at the position so that the clearance
between paper and the rear regulation plate is evenly
1mm.

NOTE: The positions of the regulation plates are even

to the right and left marks.

1)  Press the lock button on the front cabinet and lower the

paper feed base tray to the paper supply position. Pull
out the tray.

2)  Adjust the diagonal feed.

Loosen the blue screw (A) on the front regulation plate.

Referring to the degree of diagonal feed, move the regula-
tion plate in the direction of (–) and fix the blue screw.

MX-M1205  ADJUSTMENTS  5 – 31

Loosen the blue screw (A) on the front regulation plate.

Referring to the degree of diagonal feed, move the regula-
tion plate in the direction of (+) and fix the blue screw.

3)  Set a sheet of paper on the paper feed base tray and

adjust the regulation plate width.

NOTE: After completion of the adjustment, check that
the front regulation plate and the rear regulation plate
are in parallel to each other.

NOTE: When installing this machine in a place of low

atmospheric pressure, check and conform to the
adjustment contents in the MX-LC13N Service
Manual.

b)

a)

Pull out the paper feed tray until it stops.

b)

Loosen the stopper fixing screw on the lower right
side of the paper feed tray to disable the stopper
function.

c)

Then pull out the paper feed tray again until it stops.

d)

Loosen the front/rear paper guide fixing screw, and
shift the paper guides on the front and the rear sides
back and forth.

e)

Shift the auxiliary paper guide back and forth by the
same amount as the change in the paper guide posi-
tion.

f)

Tighten the fixing screws of the paper guide and the
auxiliary paper guide.

g)

Push the paper feed tray in enough to reattach the
stopper plate.  Once the stopper plate has been reat-
tached, confirm its operation. 

8)

Press [EXECUTE] key.

The adjustment pattern is printed.

9)

Check that the adjustment pattern image is printed in the cor-
rect position.

Perform the procedures 7 thru 9 until the adjustment pattern is
center aligned.

10) When the adjustment pattern is center aligned, perform 

the fine adjustment by simulation if necessary. 
(90cpm machine only)

Enter the adjustment value, and press [EXECUTE] button.

The adjustment pattern is printed.

When the adjustment value is increased, the image is shifted
to the front frame side. When the adjustment value is 
decreased, the image is shifted to the rear frame side. 

A change in the adjustment value by 1 corresponds to a shift
by about 0.1mm.

11) Check that the adjustment pattern image is printed in the cor-

rect position.

Measure the void area sizes of the adjustment pattern on the
front edge and the rear edge, and check that the sizes satisfy
all the following conditions.

RV: REAR VOID AREA
FV: FRONT VOID AREA
RV +  FV 

 5.0mm

RV = 2.5mm or less  
FV = 2.5mm or less

Perform the procedures 10 and 11 until the above conditions
are satisfied. 

 

This adjustment is required in the following cases:

* When the scanner (reading) section is disassembled.

* When the scanner (reading) unit is replaced.

* When the CCD unit is replaced.

* When the U2 trouble occurs.

* When the scanner control PWB is replaced.

* When the EEPROM on the scanner control PWB is replaced.

1)

Make an adjustment chart on A4 (11 X 8.5) paper as shown in
the figure below.

2)

Set the adjustment chart on the document table, and make a
copy.

3)

Check the copy image center position.

If A-B = 

 2.6mm or less, the adjustment is not required. 

If the above condition is not satisfied, perform the following
procedures.

4)

Enter the Sim. 50-12 mode.

5)

Select the adjustment mode OC with the scroll key.

6)

Enter the adjustment value with 10-key, and press [OK] key.

The set value is set.

When the set value is increased, the scan image position is
shifted to the front side.

A change in the adjustment value by 1 corresponds to the scan
image position by about 0.1mm.

Press [CLOSE] key to jump from the simulation mode to the
copy mode.

Repeat the procedures 2 thru 6 until the above conditions are
satisfied.
