CAUTION

This product is a class 1 laser product that complies with 21CFR 1040.10 and 1040.11 of the CDRH standard and IEC825. This means that this
machine does not produce hazardous laser radiation. The use of controls, adjustments or performance of procedures other than those specified
herein may result in hazardous radiation exposure.
This laser radiation is not a danger to the skin, but when an exact focusing of the laser beam is achieved on the eye’s retina, there is the danger of spot
damage to the retina.
The following cautions must be observed to avoid exposure of the laser beam to your eyes at the time of servicing.

1) When a problem in the laser optical unit has occurred, the whole optical unit must be exchanged as a unit, not as individual parts.

2) Do not look into the machine with the main switch turned on after removing the developer unit, toner cartridge, and drum cartridge.

3) Do not look into the laser beam exposure slit of the laser optical unit with the connector connected when removing and installing the optical
system.

4) The middle frame contains the safety interlock switch.
Do not defeat the safety interlock by inserting wedges or other items into the switch slot.

Warning!

This product is a class A product.
If it is operated in households, offices or similar surroundings, it can produce radio interferences at other
appliances, so that the user has to take adequate countermeasures.

interrupt the job and disconnect the power plug.

It may cause a fire or an electric shock.

3) Be sure to connect the grounding wire. If an electric leakage

occurs without grounding, a fire or an electric shock may be the
result.

To protect the machine and the power unit from lightening, ground­ing must be made.

4) When connecting the grounding wire, never connect it to the fol-

lowing points.

It may cause an explosion, a fire or an electric shock.

• Gas tube

• Lightning conductor

• A water pipe or a water faucet, which is not recognized as a
grounding object by the authorities.

• Grounding wire for telephone line

5) Do not damage, brake, or work the power cord.

Do not put heavy objects on the power cable. Do not bend it forc­ibly or do not pull it extremely.

It may cause a fire or an electric shock.

6) Keep the power cable away from a heat source.

Do not insert the power plug with dust on it into a power outlet.

It may cause a fire or an electric shock.

7) Do not put a receptacle with water in it or a metal piece which may
drop inside the machine.

It may cause a fire or an electric shock.

8) With wet or oily hands, do not touch the power plug, do not insert
the telephone line jack, do not operate the machine, or do not per­form servicing.

It may cause an electric shock.

2. Precautions for servicing

1) When servicing, disconnect the power plug, the printer cable, the
network cable, and the telephone line from the machine, except
when performing the communication test, etc.

It may cause an injury or an electric shock.

2) There is a high temperature area inside the machine. Use an
extreme care when servicing.

It may cause a burn.

3) There is a high voltage section inside the machine which may
cause an electric shock . Be careful when servicing.

4) Do not disassemble the laser unit. Do not insert a reflective mate­rial such as a screwdriver in the laser beam path.

It may damage eyes by reflection of laser beams.

5) When servicing with the machine operating, be careful not to
squeeze you hands by the chain, the belt, the gear, and other driv­ing sections.

damage to properties would be resulted.

6) Do not leave the machine with the cabinet disassembled.

Do not allow any person other than a serviceman to touch inside
the machine. It may cause an electric shock, a burn, or an injury.

7) When servicing, do not breathe toner, developer, and ink exces­sively. Do not get them in the eyes.

If toner, developer, or ink enters you eyes, wash it away with water
immediately, and consult a doctor if necessary.

8) The machine has got sharp edges inside. Be careful not to dam­age fingers when servicing.

9) Do not throw toner or a toner cartridge in a fire. Otherwise, toner
may pop and burn you.

10) When replacing the lithium battery of the PWB, use a specified one
only.

If a battery of different specification is used, it may be broken,
causing breakdown or malfunction of the machine.

11) When carrying a unit with PWB or electronic parts installed to it, be
sure to put it in an anti-static-electricity bag.

It may cause a breakdown or malfunctions.

3. Note for installing site

Do not install the machine at the following sites.

1) Place of high temperature, high humidity, low temperature, low
humidity, place under an extreme change in temperature and
humidity.

Paper may get damp and form dews inside the machine, causing
paper jam or copy dirt.

For operating and storing conditions, refer to the specifications
described later.

2) Place of much vibrations

It may cause a breakdown.

3) Poorly ventilated place

An electro-static type copier will produce ozone inside it.

The quantity of ozone produced is designed to a low level so as
not to affect human bodies. However, continuous use of such a
machine may produce a smell of ozone. Install the machine in a
well ventilated place, and ventilate occasionally.

4) Place of direct sunlight.

Plastic parts and ink may be deformed, discolored, or may undergo
qualitative change.

It may cause a breakdown or copy dirt.

5) Place which is full of organic gases such as ammonium

The organic photoconductor (OPC) drum used in the machine may
undergo qualitative change due to organic gases such as ammo­nium.

Installation of this machine near a diazo-type copier may result in
dirt copy.

6) Place of much dust

When dusts enter the machine, it may cause a breakdown or copy
dirt.

7) Place near a wall

(2) MG roller main pole position adjustment

1) Put the developing unit on a flat surface.

2) Tie a needle or pin on a string.

3) Hold the string and bring the needle close to the MG roller horizon­tally. (Do not use paper clip, which is too heavy to make a correct
adjustment.) (Put the developing unit horizontally for this adjust­ment.)

4) Do not bring the needle into contact with the MG roller, but bring it
to a position 2 or 3mm apart from the MG roller. Mark the point on
the MG roller which is on the extension line from the needle tip.

5) Measure the distance from the marking position to the top of the
doctor plate of the developing unit to insure that it is 18mm.

If the distance is not within the specified range, loosen the fixing
screw A of the main pole adjustment plate, and move the adjust­ment plate in the arrow direction to adjust.

balance adjustment (Rail height adjustment)

When there is no skew copy in the mirror base scanning direction and
there is no horizontal error (right angle to the scanning direction), the
adjustment can be made by adjusting the No. 2/3 mirror base unit rail
height.

Before performing this adjustment, be sure to perform the horizontal
image distortion adjustment in the laser scanner section.

This adjustment must be performed in the following cases:

• When the mirror base wire is replaced.

• When the copy lamp unit and no. 2/3 mirror unit are replaced.

• When the mirror unit rail is replaced and moved.

• When La > Lb
Shift the mirror base B rail upward by the half of the difference of
La–Lb.

• When La < Lb
Shift the mirror base B rail downward by the half of the difference
of Lb–La.

Example: When La = 12mm and Lb = 9mm, shift the mirror base

• When Lc >Ld
Shift the mirror base B rail downward by the half of the difference
of Lc–Ld.

• When Lc < Ld
When Lc < Ld, move the mirror base B on the paper feed side
upward.

This adjustment is basically O.K. with SIM 63-7.

(16) SPF scan position auto adjustment

[Function]

Used to adjust the SPF scan position automatically.

[Operation]

1) With the SPF or the OC cover open, place a chart of black back­ground on the OC glass. (In the SPF standard model, the SPF
glass surface is included.)

∗

Use a black chart (UKOG-0011QSZZ) or prepare a chart as shown
below.
Chart size: 310 x 470, prepared with cutting sheet No. 791 (Black) or
an equivalent one.

Reason: To prevent erroneous detection by disturbing light of a fluo-

2) Enter SIM53-08, and press [START] button.

<Note>

• After completion of the SPF scan position auto adjustment, the SPF

lead edge adjustment must be executed. (Both surfaces)

• There must be no other sheet than the black chart on the glass sur-

face.

• Especially when in SPF scan, the center area is scanned in the main

scan direction. Be careful to prevent external light from entering the
scan area.

3) Check that the lead edge is not shifted. (Both surfaces)

Place only the black
chart on the OC glass.

rescent lamp, etc.

Outline of SIM: The optical unit is shifted to recognize the bound­ary between the OC glass and the SPF glass cover.
With the same position as the reference, the SPF scan position is
automatically adjusted.

(If the original lead edge adjustment has been made properly, even
when the scan position is shifted, it is followed automatically.)

For the SPF standard-provision
machine, check that the black
chart covers the SPF glass.

Placing the black chart
The black chart must cover
this area.

C. Image density (exposure) adjustment

1) Set a test chart (UKOG-0162FCZZ) on the OC table as shown
below.

Rear

Front

2) Place three or more sheets of A3 (11" x 17") paper on the test
chart.

3) Execute SIM 46-2.

4) After warm-up, shading is performed and the current set value of
the density (exposure) level is displayed on the display section in 2
digits.

For mode selection, use the [10-key].

5) Change the set value with the [10-key] to adjust the copy image
density.

6) Make a copy and check that the specification below is satisfied.
