[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.

(8), it may need to be adjusted depending on the type of originals.
The leading edge position can be adjusted within a range of 8 mm
(8 steps) on the stopper side and 7 mm (7 steps) on the glass side
in 1 mm increments. Adjustment can be done separately for the
one-sided, two-sided, and thin paper modes.

Place 2 or more sheets in the ADF and make copies in the staple sort
mode. Confirm that the copies are distributed to the sort bins, that the
staple guide bar arranges the copies and that the stapler functions
properly.

If at this time the copies have not been stapled or the stapler is
jammed, adjust the staples by performing one of the following proce­dures.

If copies have not been stapled

1. Remove the staple cartridge.

Open the stapler cover, lift up on the staple cartridge and remove it

Mirror base wire stretching

(Preliminary checks)

Check the stop position of the wire winding pulley.
Visually check that the wire grooves of the front/rear wire winding

pulleys are at the same level.
If there is a substantial discrepancy between the two, loosen the two

setscrews which are fixing the pulleys and adjust the pulley positions.
After adjustment, tighten the setscrews.

1 Hang the mirror base wire fixing fixture on the tension adjustment

plate hook.

2 Fit mirror base B onto the mirror base positioning plates

(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.

(Rear frame side)

(Rear)

(Fron t)

The first winding position should be 9 - 10mm toward the body
frame from the pulley groove section.

5 Pass the mirror base wire along the pulley groove in the paper exit

side.

base B pulley.

7 Pass the mirror base wire through the wire guide.
8 Attach the mirror base wire tension spring to the long hole in the

which is at the mirror base positioning plate 20 to 30mm to the
paper exit side.

2 Turn the mirror base wire tension adjustment screw clockwise to

apply tension to the wire until the wire tension spring edge makes
contact with the projection of mirror base B.

spring edge is in contact with the projection of mirror base B. If
they are not in contact with each other, adjust by turning the
tension adjustment screw again. In this case, check also that
there is no slack in the wire on the mirror base pulley.

4 Turn the mirror base wire tension adjustment screw 6 turns

counterclockwise. (Then the distance between the mirror base
wire spring and the projection of mirror base B will be about
4mm.)

This adjustment is to adjust parallelism of the mirror base B to the
drum surface and the original surface.

1 Manually turn the mirror base drive pulley to bring mirror base B

into contact with the mirror base positioning plate. In this case,
when the front frame side and the rear frame side of mirror base B
are simultaneously brought into contact with the mirror base
positioning plate, the parallelism of mirror base B is proper and
there is no need for adjustment.

ing doctor blade and the magnet roller at the points 50-80 mm
away from both ends.

4 While pressing down the developing doctor blade in the arrow

direction, tighten the 4 setscrews to secure the developing doc­tor blade.

5 Check that the clearance between the developing doctor blade

mode when the message feed key is pressed.

Mode Figure Grid voltage
Normal 56 –650V
TSM 52 –550V
Photo 50 –440V

NORMAL (Normal mode)

Set value: 650 = –650V output
To decrease the measurement voltage, make the set value
smaller. (1 step: 1V)
To increase the measurement voltage, make the set value
greater.

T/S (TSM mode)

Set value: 550 = –550V output
To decrease the measurement voltage, make the set value
smaller. (1 step: 1V)
To increase the measurement voltage, make the set value
greater.

PHOTO (Photo mode)

Set value: 440 = –440V output
To decrease the measurement voltage, make the set value
smaller. (1 step: 1V)
To increase the measurement voltage, make the set value
greater.

(Measure at check point CP-GB)

4 Remove the rear cover.
5 Connect the digital multimeter to the grid voltage pin (GB).
6 Set the measuring range of the digital multimeter to DCV.

Vdc).

7 Turn on the front cover switch manually.
8 There is another method to check the grid votage as follows:

Turn on the main switch, and adjust the output adjusting control
so that output voltage values in Simulation "8-02"(normal mode),
"8-03"(photo mode) and "8-04"(TSM mode) are as follows:

TEST POINT CP-GB Output Voltage

Normal mode –650±5V

TSM mode –550±5V

Photo mode –440±5V
