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.

MX-B381/B401 MX-B381/B401 (MAIN UNIT) 1 – 2
(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
A. Implements, facility, and manpower
It is recommendable to use a forklift for bringing in the machine for
safety.
If no forklift is available, man-power of two persons is required. The
machine is considerably heavy, and requires safety precautions for
delivery and installation.
Transit of the machine must be made in packed condition to the
installing place.
Since the hard disk drive is built in the machine, use care not to
exert vibrations or shocks to the machine when in transit.
B. Delivery
Remove the packing materials prior to installation in the office environment.
3. Unpacking
A. Unpacking procedure
1) Remove the PP band.
2) Remove the top case.
3) Remove the parts included in the package.
No. Content Method
1 Implements, facility,
and man power
Use a forklift. (If no forklift is available,
manpower of two persons is required.)
2 Delivery Transit must be made in packed condition.

3) Turn the lock lever to the horizontal position to release the
lock, and open the drum positioning plate unit.
4) Shake the developer cartridge 5 - 6 times horizontally, and
remove the protection material from the developer cartridge.
Insert the developer cartridge straight and horizontally until it
locks.
NOTE: When handling the developer cartridge, do not touch the
magnet roller section and the shutter section.
5) While pressing the developer cartridge, pull out the heat seal
straight.
NOTE: If the heat seal is pulled out with a strong force or diago-
nally, it may be broken off. Be sure to pull it slowly and
straight.
After puling out the heat seal completely, check to confirm
that there is a red mark at the edge of the heat seal.
If there is no red mark, it means that the heat seal has been
broken. In such a case, the developer cartridge must be
replaced with a new one.
6) Close the lock cover of the developer cartridge.
7) Close the drum positioning plate unit, and put the lock lever
upright to lock.
