MX-M316N  ADJUSTMENTS AND SETTINGS  5 – 13

 

This adjustment must be performed in the following cases:
* The CCD unit has been removed from the machine.
* The CCD unit has been replaced.
* When the copy image focus is not properly adjusted.
* When the copy magnification ratio in the copy image main scan-

ning direction is not properly adjusted.

* U2 trouble has occurred.
1) Enter the SIM 48-1 mode.

2) Set the adjustment item CCD (MAIN) to 50 (default value).

Select the adjustment item with the scroll key, and enter the
adjustment value with 10-key and press [OK] key.

3) Place a scale on the original table as illustrated below.

4)

Make a normal copy on A4 paper.
Go to the copy mode, and make a copy.

5)

Compare the copied image of the scale and the actual scale
length in terms of length.

6)

Obtain the copy magnification ratio correction ratio in the main
scanning direction from the following formula.
Main scanning direction copy magnification ratio correction
ratio = (Original size - Copy image size) / Original size x 100%
(Example) 
Compare the scale of 10mm with the scale of 10mm on the
copy image.
Main scanning direction copy magnification ratio correction
ratio = (100 - 99) / 100 x 100 = 1

If the copy magnification ratio is not satisfactory, perform the
following procedures.

7)

Remove the document table glass.

8)

Remove the dark box cover.

9)

To prevent against shift of the CCD unit optical axis, mark the
CCD unit base as shown below.

NOTE: MEMO: This procedure must be executed also when the

CCD unit is replaced.

10) Loosen the CCD unit fixing screws.

CAUTION: Never loosen the screws marked with X.

If any one of these screws is loosened, the position and
the angle of the CCD unit base may be changed to
cause a problem, which cannot be adjusted in the mar-
ket. In that case, the whole scanner unit must be
replaced.

11) Slide the CCD unit in the arrow direction (CCD sub scanning

direction) to change the installing position.
When the copy image is longer than the original scale, shift the
CCD unit in the direction B. When the copy image is shorter
than the original scale, shift the CCD unit in the direction A.
One scale of mark-off line corresponds to 0.2%.
At that time, fix the CCD unit so that it is in parallel with the
scale on the front and the rear side of the CCD unit base.
* Fix the CCD unit so that it is in parallel with the line marked

in procedure 9).

12) Make a copy and check the copy magnification ratio again.

If the copy magnification ratio is not in the range of 100 

repeat the procedures of 9) - 11) until the condition is satisfied.

CAUTION: By changing the CCD unit fixing position with the simu-

lation 48-1 adjustment value at 50, the copy magnifica-
tion ratio is adjusted within the specified range (100 

1.0%) and the specified resolution is obtained based on
the optical system structure.

 

This adjustment must be performed in the following cases:
* When the registration roller section is disassembled.
* When the LSU is replaced or removed.
* U2 trouble has occurred.
* The PCU PWB has been replaced.
* The EEPROM of the PCU PWB has been replaced.

NOTE: This adjustment is performed by the user to increase the

lead edge void area to greater than the standard value
(3mm) in the printer mode.

1)

Enter the SIM 50-5 mode.

2)

Select the set item L with the scroll key, and enter the value
corresponding to the paper feed tray with A4 (11" x 8.5") paper
in it.

3) Press [EXECUTE] key.

The adjustment pattern is printed.

4) Measure the distance from the paper lead edge the adjustment

pattern to the image lead edge, and check to confirm that it is
in the standard adjustment value range.
Standard adjustment value: 4.0mm or less

If the above requirement is not met, do the following steps.

5) Select the adjustment target of the paper feed mode adjust-

ment item DENC with the scroll key.

6) Change the adjustment value.

Enter the adjustment value and press the [OK] key or the
[EXECUTE] key.
When [EXECUTE] key is pressed, the adjustment pattern is
printed.
When the adjustment value is increased, the distance from the
paper lead edge to the image lead edge is increased. When
the adjustment value is decreased, the distance is decreased.
When the set value is changed by 1, the distance is changed
by about 0.1mm.

Repeat the procedures 4) - 6) until the condition of 4) is satisfied.

 

Make a copy of the gray test chart (UKOG-0162FCZZ) and a copy
of the servicing color test chart (UKOG-0326FCZZ/UKOG-
0326FC11), and check that they are proper.

Note for checking the monochrome copy mode density
To check the density, use the gray test chart (UKOG-0162FCZZ).
Set the copy density level to "Manual 3" in the Text/Printed Photo
mode (Manual).
In addition, all the color balance adjustments in the user adjustment
mode must be set to the default (center).

Check with the gray test chart (UKOG-0162FCZZ)
In the copy density check with the gray test chart, check to insure
the following conditions.

CAUTION: For the color (gray) balance, use the servicing color test

chart (UKOG-0326FCZZ/UKOG-0326FC11) to check.
