MX-7580N  MX-LC13 N (LARGE CAPACITY TRAYS)  7 – 13

Loosen the 2 blue screws (1) on the front regulation plate.

Referring to the degree of diagonal feed, move the regulation
plate in the counterclockwize direction and fix the blue screw.

Loosen the 2 blue screws (2) on the rear regulation plate.

To make parallel with the front regulation plate, move the rear
regulation plate in the counterclockwize direction and fix the
screws.

NOTE: When fixing the rear regulation plate, not to fix it more

closely against the paper.

(The target of the gap between the edge of paper and the
rear regulation plate is about 1.0mm)

NOTE: After completion of the adjustment, check that the front reg-

ulation plate and the rear regulation plate are in parallel to
each other.

In order to avoid the unstable installation, underlay the adjustment
bolt with the adjuster and fix LC13 to the floor.

NOTE: Fix the right side adjuster not to change the height level of

LC13 largely.

NOTE: If the fixation of LC13 is unstable, it might be moved when

insert the tray to the unit.

If there’s some gap between cabinets or door adjustment is neces-
sary, adjust the height adjustment.

1)

Install the adjuster (Packed items No.3) and adjuste the height
of LC13 (4 places)

2)

Adjust height in order to make the gap evenly of  each cabinet
as the figure below.

3)

Adjust height in order to make the height and the gap evenly of
each cabinet as the figure below.

The image lead edge position and the off-center adjustment value
of the desk unit have been set to the average value when shipping
from the factory. 
Therefore, this adjustment must be performed only when the judg-
ment is made to execute it through checking the print image.

* There must be a tray with A4 (LT) paper in it.

1)

Enter the Sim. 50-10 mode.

2)

Select a paper feed source “K“ (MAIN-LCT1).

3)

Set A4 (11 X 8.5) paper on the LCC paper feed tray.

4)

Check to confirm that the inside dimension of the printed half-
tone pattern is 240

0.5mm.

If the above condition is not satisfied, follow and repeat the
procedures of ADJ3A(Service manual) until a satisfactory
result is obtained.

5)

Measure the void area size of the adjustment pattern in the
front/rear frame direction (F side void amount) and that in the
transport direction (Lead edge void amount).

Check to confirm that all the following conditions are satisfied.

(Example) Lead edge void amount

(1) Measure by visual inspection.

Measurement result: 3.5mm

(2) Calculate the shift amount.

The target value is the specification value (center value) of
3mm.

* For the F side void amount, the target is 2mm.
[3 – 3.5 = -0.5 (mm)]

(3) Calculate the adjustment value.

Subtract 5 from the shift amount of -0.5mm.

* For the shift amount of 0.1mm, the adjustment value is

varied by 1.

When the current value is 50:

[50 – 5 = 45]

(4) Enter the adjustment value for SUB-LC.

Enter the [45].

6)

Enter MAIN-LCT1 (F side void) and SUB-LC (Lead edge void),
and press OK button.

Enter the calculated adjustment values for the shift amount to
MAIN-LCT1/SUB-LC, and press OK button. (The cursor can
be used instead of the button.)

7)

After entering the adjustment values, print again and check to
confirm that the avoid amounts are adjusted to the target
range.

Perform procedures 4) to 7) for each paper feed tray.

NOTE: Before installation, be sure to turn both the operation and

main power switches off and disconnect the power plug
from the power outlet. Make double sure that the data lamp
on the operation panel does not light up or blink when per-
forming installation.

1)

Draw out the second tray from the unit.
Push the button of the bottom side of the unit to unlock the
tray, and then slowly pull out the tray until it stops.

2)

Remove 3 screws from the tray.

3)

For 19 inch size paper, remove the step screw.

4)

Slowly insert the tray to the original position.

1)

Attach the LCT connecting plate to the large capacity trays
with the screws (Packed items No.4 S-tight, M4 x 8).

3)

Insert the installation plate of the LCT to the mounting plate of
the paper pass unit.

4)

Install the adjuster (Packed items No.3) and adjuste the height
of LC13 (4 places)
