Service Manual

[1] MX-B381/B401 (MAIN UNIT)

1. Installing (use) conditions

Before installing the machine, check that the following installing
(use) conditions are satisfied.

If the installing (use) conditions are not satisfied, the machine may
not display full performances, resulting in troubles. It may also
cause safety problems. Therefore, be sure to arrange the installing
(use) conditions before setting up the machine.

A. Bringing space

For installation of a large size machine, be sure to check that the
door size is wide enough before bringing in.

B. Installing space

The following space must be provided around the machine in order
to assure machine performances and proper operations.

If any option is installed, provide the additional space for installing
it.

Especially the space at the rear of the machine must be provided
sufficiently. If not, the machine cannot exhibit functions against heat
and dust, causing some troubles.

C. Power source (Capacity, voltage, frequency,

safety, plug)

If the power specifications are not satisfied, the machine cannot
exhibit full performances and may cause safety trouble.

Strictly observe the following specifications.

(1) Power capacity

Check that the following power capacity is satisfied. If not, addition­ally provide a power source.

Current capacity

Japan: 20A or more

100V: 15A or more

200V: 10A or more

(2) Power voltage

Measure the voltage during copying to check that the voltage is in
the range of the specified voltage 10%.

If the voltage is outside the specified range, use thicker lead wires
to reduce impedance.

(An electrical work is required.)

Use of a step-up transformer is also available. In this case, the
capacity must be great enough for the max. power consumption of
the machine.

(3) Power frequency, waveform

The frequency must be within the range of the specified frequency
2%. If power waveform is deformed, a trouble may occur.

(4) Safety

Be sure to properly ground the machine.

Grounding (earth connection) must be performed before inserting
the power plug into the power outlet.

When disconnecting the earth connection, be sure to disconnect
the power plug from the power outlet in advance.

(5) Power plug

Check the form of the power plug. If the shape does not match, do
not use it.

D. Floor strength and level

This machine is considerably heavy and becomes heavier with an
option installed.

The floor must be strong enough for assuring safety.

If the unit is not horizontally installed, the toner density control is not
performed normally, degrading the copy quality.

If not, color shift or image distortion may occur.

E. Direct rays of the sun, dust, temperature,

humidity, gasses, chemicals, vibration

(1) Temperature and humidity

This machine is designed to perform properly under the specified
temperature and humidity. If the temperature and humidity exceeds
the specified range, the machine may not operate properly and or
cause equipment failure.

Especially when the humidity is too high, paper absorbs humidity to
cause a paper jam or dirty copy.

Do not install the machine near a heater, a cooler, or a humidifier.

Dew may be formed inside the machine to cause a trouble. Use
enough care for ventilation.

(2) Dust

If dust enters the machine, it may cause dirty copy and a paper
jam, resulting in a shortened lifetime.

(3) Direct rays of the sun

If the machine is installed under the rays of the sun, the exterior of
the machine may be discolored and abnormal copies may be pro­duced.

(4) Gases and chemicals

Do not install the machine at a place where there are gases and
chemicals. Especially be careful to avoid installation near a diazo­type copier, which produces ammonium gas.

Copy quality may be adversely affected and a trouble may be
caused.

(5) Vibration

Avoid installation near a machine which produces vibrations.

If vibrations are applied to the copier machine, copy images may be
deflected and a trouble may be caused.

2. Transit and delivery

6) Bind the desk dehumidifier heater harness and the WH desk I/
F harness with the snap band, and insert them into the round
hole in the 500-sheet paper feed unit.

Cut the lead edge of the snap band with about 5mm edge left.

F. Dehumidifier heater resistance check

1) Insert a tester between pin 1 and pin 3 of CN3 of the WH PWB
of the main unit, and check to confirm that the resistance is as
shown below.

Though the MX-CSX2 is installed, if the dehumidifier heater kit
is installed only to the MX-CSX1, the measurement value is
that "When one MX-CSX1 is installed."

G. Install the desk cabinet in the reversed

sequence of item A.

1) Install the desk cabinet and tighten the screw.

* Use enough care not to pinch the harness.

H. Desk fixing

1) Return the lock plate which is on the left side when viewed
from the machine front to the original position, and tighten the
hand screw.

2) Fix the lock plate with the M4 x 10 P tight screws. (3 positions)

* This screw is installed so that the end user cannot remove

the MX-CSX1/CSX2 easily. Be careful not to forget installa­tion of this screw.

When the dehumidifier heater kit for the 500 paper feed unit is
installed to the machine with the dehumidifier heater kit
installed in advance, the procedure of I and J are not required.

I. Addition of the holes for the dehumidifier

heater switch

1) Cut off the notch of the square hole for the dehumidifier heater
switch on the rear cabinet.

2) Attach the heater switch label (No.2) (which is packed together
with the dehumidifier heater kit for the machine) to the con­caved section of the rear cabinet.

3) Cut the inside section of the rear cabinet where the harness
passes through.

J. High temperature caution label attachment

1) Pull out the paper tray 1, and clean the caution label attach­ment section with alcohol.

2) Attach the caution label (which is packed together with the
dehumidifier heater kit for the main unit) to the paper tray.

K. Attach the rear cabinet.

3. Check after installation

1) Turn ON the dehumidifier heater switch. (Press the upper sec­tion of the switch.)

2) Measure the resistance between the earth terminal and the AC
terminal at the lead edge of the AC cord with a tester, and
check to confirm that the resistance is infinite.

* Check the resistance between the non-grounding side (Live)

and the grounding side and between the non-grounding side
(Neutral) and the grounding side.

* If there is conduction between the grounding terminal and

the AC terminal, the harness on the primary side may be in
contact with the grounding wire (the wire may be pinched or
in some trouble). In this case, disassemble it again and
check to confirm that there is no pinching or wiring mistake.

ALL RIGHTS RESERVED.

The PWB’s of this model employs lead-free solder.The “LF” marks indicated on the PWB’s and the Service Manual mean “Lead-Free” solder.

LEAD-FREE SOLDER

The alphabet following the LFmarkshows the kind of lead-free solder.

(1) NOTE FOR THE USE OF LEAD-FREE SOLDER THREAD

When repairing a lead-free solder PWB, use lead-free solder thread.

Never use conventional lead solder thread,which may cause a breakdown or an accident.

Since the melting-point of lead-free solder thread is about 40°C higher than that of conventional lead solder thread, the use of the
exclusive-use soldering iron is recommended.

(2) NOTE FOR SOLDERING WORK

Since the melting-point of lead-free solder is about 220°C,which is about 40°C higher than that of conventional lead solder, and its soldering
capacity is inferior to conventional one, it is apt to keep the soldering iron in contact with the PWB for longer time.This may cause land
separation or may exceed the heat-resistive temperature of components.Use enough care to separate the soldering iron from the PWB when
completion of soldering is confirmed.

Since lead-free solder includes a greater quantity of tin, the iron tip may corrode easily.Turn ON/OFF the soldering iron power frequently.

If different-kind solder remains on the soldering iron tip, it is melted together with lead-free solder.To avoid this, clean the soldering iron
tip after completion of soldering work.

If the soldering iron tip is discolored black during soldering work, clean and file the tip with steel wool or a fine filer.
