[5] INSTALLATION

A. Installing conditions

To ensure safety and proper machine performance, please note the
following before initial installation and whenever the machine is to be
relocated.

1. The copier should be installed near an accessible power outlet for
easy connection.

2. Be sure to connect the power cord only to a power outlet that
meets the specified voltage and current requirements.
Also make certain the outlet is properly grounded.

3. Do not install the machine where it is:

• damp or humid,

• exposed to direct sunlight,

5. Be sure to allow the required space around the machine for ser­vicing and proper ventilation.

11-13/16"
(30cm)

12/8"
(60cm)

12/8"
(60cm)

A small amount of ozone is produced within the copier during
operation.
The emission level is insufficient to cause any health hazard.

NOTE:

The present recommended long term exposure limit for ozone is

0.1 ppm (0.2 mg/m3) calculated as an 8 hr. time-weighted average
concentration.
However, since the small amount that is emitted may have an
objectionable odor, it is advisable to place the copier in a
ventilated area.

00-13/16"
(30cm)

• extremely dusty,

• poorly ventilated,

• subject to extreme temperature or humidity changes (e.g., near

an air conditioner or heater).

4. Ensure that the area chosen for the machine location is level.

(front/rear). Pass the mirror base wire along the outer groove of
the mirror base B pulley.

3 Pass the mirror base wire along the pulley groove in the paper

feed side.

4 Pass the mirror base wire under mirror base B and wind it around

the winding pulley.
At that time, fix the wire groove section in the winding pulley to the
upper position, wind the mirror base wire 9 times, and put the 8th
winding in the groove.

If the preset reference value is larger than the mid value "42",
the 4. and 5. mirrors are set further away from lens.
If the preset reference value is smaller than mid value "42",
the mirrors are set closer to lens.

(3) Adjusting the Longitudinal Magnification

This adjustment must be done while the mirror bases A, B and C
are in parallel with each other and the lens is focalized.

• When the lens home position sensor (LHPS) is moved or

replaced.

• When the lens is replaced.

• When the mirror base is moved or replaced.

• When the main PWB is replaced.

• When self diag U2 occurs.

• When RAM in the main PWB is replaced.

(4) Adjusting the Resolution

Applied Material: UKOG-0089CSZZ (Test chart)

1 Perform Simulation 48-01 to check that a preset value cor-

responds to a focal length of lens used:
C → 0/◊ → 0/↵ → =↵ → 4 → 8 → PSW →
1 → PSW .

When the ready lamp is lit, a preset value is indicated.

2 If no preset value exists, set a reference value according to

(2)"Adjusting the reference position of 4. and 5. mirror". Then
take a copy of "UKOG-0089CSZZ" and check the resolution.

3 When changing a preset value:

→ → PSW .

Checking Procedure
After adjusting the reference position of 4. and 5. mirror, check as
follows:
1 Set the test chart UKOG-0089CSZZ or a resolution test chart on

the original table.

2 Take a full-size copy.
3 Check if the center and corners of the copy paper is in focus.
4 The resolution must be at least 5.0 lines/mm in the center and

4.5 lines/mm in the corners. Otherwise, repeat the steps 2 to 4
of (2) while changing the preset value by 1 at a time, until this
requirement is met.

(5) Adjusting the Lateral Magnification

The lateral magnification should be adjusted in the following cases:

• When the main PWB is replaced.

• When the RAM in the main PWB is replaced.

• When self diag U2 occurs.

• When the mirror motor is replaced.

Change the mirror base scan speed to adjust the lateral magnifica­tion ratio.
1 Set a scale on the original table as shown in the figure and

perform Simulation 48-02.
The machine starts the warm-up cycle and the ready lamp is lit.
At the same time a preset value (ranging from 15 to 35) is
indicated.
Now take a full-size copy of the scale and determine the correc­tion factor for lateral magnification according to the following
expression:
Correction factor for lateral magnification = [(original size – copy
size)/original size] x 100 (%)

2 Use the correction factor to change the indicated value:

Value to be input = (preset value) + (correction factor for lateral
magnification(%)) x 10

• Eg.1: 35 = 25 + 1 x 10

• Eg.2: 15 = 25 + (–1 x 10)

When a new value is typed and the print switch is pressed, the
new value is stored in memory and the ready lamp goes off.

3 Clear Simulation 48-02.

Note: In Simulation 48-02 the correctable range of the

preset value is limited from15 to 35.

(6) Inputting the Lens Travel Correction Value

(Simulation 26-08, 26-09)

<Inputting the lens characteristics>

The lens varies in focal length for each machine. The lens travel is
required to correspond to the focal length of the lens. If the lens
travels at a magnification would be constant among the machines
in spite of the focal length irregularity, the magnification could vary
depending on this irregularity.
To avoid this problem, we have prepared the table showing focal
length ranks of lens and correction data (see the next page) which
can be stored in memory at the time of Simulations described
below. In order to copy properly at a magnification, the lens travel
corresponding to its focal length is calculated on the basis of the
stored data.

<When lens is replaced>

1 Set correction data according to the "focal length ranks of lens

and correction data" table at following Simulation:
C → =↵ → 0/↵ → =↵ → 2 → 6 → PSW →
9 → PSW to perform Simulation 26-09.

When the ready lamp is lit, a preset value (ranging from 1 to 21) is
indicated.
2 Input a new preset value.

Otherwise, follow the steps 4 to 7 described below:
4 Loosen screws securing the mirror base driving pulley on the

rear frame side.
If La is bigger than Lb, rotate the mirror base driving pulley on
the rear frame side in the A direction. (Do not rotate the flange
and the shaft of the mirror base driving pulley).
If La is smaller than Lb, rotate the mirror base driving pulley on
the rear frame side in the B direction. (Do not rotate the flange
and the shaft of the mirror base driving pulley).

5 Tighten the screws securing the mirror base driving pulley.
6 Repeat steps 1 to 3.
7 If La is not equal to Lb, repeat steps 4 and 5 until La=Lb.

(8) Correcting the Lateral Distortion

If the lateral distortion occurs without the longitudinal distortion(dis­tortion in the mirror base scanning direction), the lateral distortion
can be corrected by adjusting the height of 2. and 3. mirror base
and/or the eccentric roller of 4. and 5. mirror base.
The correction procedure is as follows:

A

Original

Copy

1 Preparing the reference original:

On an A3-size or 11" x 17" blank paper, draw 2 parallel lines at
the positions 10 mm away from the both ends.

2 Take a full-size copy of the paper using an A3-size or 11" x 17"

paper.

3 Measure and the distance between the paper end and the line

at 4 positions (La, Lb, Lc and Ld).

7 – 13

If La=Lb and Lc=Ld, no adjustment is required.

(Original)

2 mm

or less

Copy paper center

(Copy 1) Move lens in the A direction

(Copy 2) Move lens in the B direction

Copy paper center

If La>Lb(Lc<Ld), rotate the eccentric roller in one direction to raise
the front frame side of the 4. and 5. mirror base unit.
If La<Lb(Lc>Ld), rotate the eccentric roller in the other direction to
lower the front frame side of the 4. and 5. mirror base unit.
Note: Remember how much the roller is rotated.
(One rotation of the roller causes the height of the front frame side
to change by 2 mm and the difference between La and Lb to
change by 4 mm).
* After opening the front cabinet, the adjustment described above

can be made through the access hole.
If the above procedure does not provide sufficient adjustment, fol­low the steps shown below:
1 Move the B rail of the mirror base upward or downward (in the

arrow direction).
If La>Lb, raise the mirror base B rail on the paper discharge side
by one-half of (La-Lb).
If La<Lb, lower the mirror base B rail on the paper discharge
side by one-half of (Lb-La).
ex.:
When La=12 mm and Lb=9 mm, raise the mirror base B rail on
the paper discharge side by 1.5 mm.

If Lc>Ld, lower the mirror base B rail on the paper discharge
side by one-half of (Lc-Ld).
If Lc<Ld, raise the mirror base B rail on the paper discharge side
by one-half of (Ld-Lc).
(Grasping the grip of the mirror base rail, move the mirror base
rail).

2 Adjust the eccentric roller as described in 1) until La=Lb and

Lc=Ld.

3 After adjustment, manually rotate the mirror base driving pulley

to check that the mirror base A and B do not come into contact
with each other during full-scanning motion.

Note: If the mirror base rail is moved excessively, the mir-

ror bases may contact with each other.

(9) Adjusting the Center Deviation

Take a full-size copy and compare the copy with the original.
If the deviation of the copy center from the original center is more
than 2mm, move the lens in the arrow direction so that the deviation
is 2 mm or less.

Note: After moving the lens, adjust the position of the blank

lamp because a change of the reference center position
results in a change of the blank lamp position.

(10) Adjusting the Exposure Balance

Take a half-tone copy, and move the exposure control plate a, b, c
and d to adjust the exposure balance. Movement of the plate in the
A direction provides less exposure and the B direction more ex­posure.

4. Adjustment of Copy Density

1. When must the copy density be adjusted ?

• When doing maintenance;

• After adjusting the output current of the main charger and transfer

charger, the bias voltage of the separation charger and the grid
voltage (After replacing the charger unit and/or the high voltage
unit);

• After adjusting the developing bias;

• After replacing parts in the AC PWB unit;

• After replacing the automatic exposure sensor;

• After replacing the copy lamp;

• After replacing the optical unit;

• After disassembling, repairing and/or adjusting the optical unit;

• After moving the exposure control plate;

• After replacing the drum;

• After replacing the main substrate

2. Notes on adjustment of copy density

Before adjusting the copy density, do the followings:
1 Clean the optical system(original glass plate, lens, mirror, copy

lamp, reflector).

2 Clean the automatic exposure sensor (clean the surface of the

photosensor with a soft cloth soaked with alcohol or water).
(Note: The use of dry cloth will cause dust adhesion on the sur­face of the sensor due to static electricity).

3 Clean the (transfer and separation) charger wire and the screen

grid.

4 Clean the blank lamp and the separation lamp around the drum

holder unit.

5 Clean the drum cleaning blade. (After cleaning, always apply pow-

der on the blade).

Note: Perform the manual-exposure density adjustment first, and

then perform the auto-exposure density adjustment.

Note: • This machine automatically performs the correction to

the optical system dirt.
When Simulation 46-01 is performed, each mode cor­rection is initialized. When performing Simulation 46-01,
perform the adjustments of all modes.

• This machine automatically performs the correction to

the sensitivity due to photoconductor aging. When a
copy is made in Simulation 46-01, the correction state
will be initialized.

3. Procedure for copy density adjustment

(1) Initial setting of auto-exposure density level (User
adjustment)

1 Enter the key operator code.
2 Execute simulation No. 20.
3 Select "3" with the ten key.

The following message is displayed on the LCD.

P.20: AUTO EXPOSURE ADJUSTMENT

1. LIGHTEST 2. LIGHTER 3. NORMAL

4. DARKER 5. DARKEST

4 Press CA key to cancel the set mode.

(2) Initial setting of TSM mode (User adjustment)

1 Execute simulation 26-18.

0: Cancel, 1: Setting

2 Select "0" with the 10 key pad.

"1": TSM mode valid
"2": TS mode invalid

3 Cancel the setting mode with CA key.

(3) Adjustment of AE sensor level

1 Perform Simulation 47. (The mirror base makes scanning motion

and stops at AE sensor level measuring position).

2 Place four or five A3-size (or 11" x 17") papers one upon another

on the original table.

3 Press the print switch again. The copy quantity indicator shows

the AE sensor output level for blank paper, which is stored in
memory.

(4) Setting of drum sensitivity

1 Perform Simulation 26-07 and check that the first digit of the

4-digit drum number printed on the front-frame sided drum flange
is shown on the copy quantity indicator.

2 If the indicated number differs from the drum number, press the

copy quantity key to change the setting.
Note: If the setting is done with the copy quantity key, the indi-

cated number is limited to 1, 2 or 3.
