Machine Environment, Installation, and Transportation -i
Service Manual Machine Environment, Installation, and Transportation
1.Machine Environment and Installation
Before installing the machine, check that the following conditions are
satisfied.
If the installing (use) conditions are not satisfied, the machine may not
exhibit full performance, resulting in problems. It may also cause
safety problems. Using the following information, make sure all
aspects of installation, space, power, transportation, leveling, and
safety are met.
A.Transportation 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 performance and proper operations.
If any option is installed, provide the additional space for with installa-
tion.
Adequate space must be provide behind the machine for proper venti-
lation of heat and dust. The machine will not function properly if heat
and dust cannot be properly expelled from the machine.
C.Power source (Capacity, voltage, frequency,
safety, plug)
If the power specifications are not satisfied, the machine cannot exhibit
full with performance 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 proper power source.
Current capacity
Japan: 20A or more
EX 100V: 15A or more
EX 200V: 10A or more
Check the shape of the power plug of the machine, and insert it into a
power outlet of the acceptable shape.
(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, please have a certified
electrician upgrade the outlet.
(Electrical work is required.)
Use of a step-up transformer is also available. In this case, the capac-
ity 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 the power waveform is improper, a problem may occur with the
machine.
(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 shape of the power plug of the machine, and insert it into a
power outlet of the acceptable shape.
Power plug stated in power capacity.
D.Floor strength and level
This machine is considerably heavy and becomes heavier with an
option installed.
The floor must be strong enough to safely support the weight of the
machine as well as any installed options.
If the unit is not properly leveled, toner density may become affected
degrading the copy / print quality.
Also, color shift or image distortion may occur.
To assure proper Image quality, make sure the machine is sitting level.
E.Direct rays of the sun, dust, temperature, humid-
ity, gasses, chemicals, vibration
(1)Temperature and humidity (Environmental conditions)
This machine is designed to perform properly under the specified tem-
perature 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, an air conditioning outlet, or a
humidifier.

Machine Environment, Installation, and Transportation -ii
Condensation may form inside the machine causing multiple prob-
lems. Make sure machine has proper ventilation.
Operational environment
Temperature: 10 to 35 degree C
Humidity: 20 to 85% RH
Atmospheric pressure: 590 to 1013hPa (altitude: 0 to 2000 m)
(2)Contaminates
If dust enters the machine, it may cause dirty copy and a paper jam,
resulting in a shortened lifetime.
(3)Direct sunlight
If the machine is installed in direct sunlight, 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 chem-
icals. Especially be careful to avoid installation near a diazo-type
copier, which produces ammonium gas.
Copy quality may be adversely affected and machine problems may
arise.
(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.
F.Note for handling PWB and electronic parts
When handling the PWB and the electronic parts, be sure to observe
the following precautions in order to prevent against damage by static
electricity.
- When in transit or storing, put the parts in an anti-static bag or an
anti-static case and do not touch them with bare hands.
- When and after removing the parts from an anti-static bag (case),
use an earth band as shown below:
- Put an earth band to your arm, and connect it to the machine.
- When repairing or replacing an electronic part, perform the pro-
cedure on an anti-static mat.

Machine Environment, Installation, and Transportation -iii
G.Note for proper drum, developing, fusing and
transfer unit handling
When handling the OPC drum, developing, fusing units and transfer
units, observe the following items.
Drum unit
- To prevent damage to the OPC drum, avoid working on the drum
unit in high intensity light areas.
- When the OPC drum is removed from the machine, cover it with
light blocking material. (When using paper, use about 10 sheets of
paper to cover it.)
- Be careful not to attach fingerprints, oil, grease, or other foreign
material on the OPC drum surface.
Transfer unit
- Be careful not to "leave” fingerprints, oil, grease, or other foreign
material on the transfer roller, primary transfer belt and secondary
transfer roller.
Developing unit
- Be careful not to "leave” fingerprints, oil, grease, or other foreign
material on the developing unit.
Fusing unit
- Be careful not to "leave” fingerprints, oil, grease, or other foreign
material on the fusing roller.
- If the machine is not going to be used for an extended period,
release the pressure on the fusing rollers.
If these items are neglected, a trouble may be generated in the copy
and print image quality.
2.Transit and delivery
A.Implements, facility, and manpower
It is recommended to use a forklift when moving the machine.
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 install-
ing place.
B.Delivery
Remove the packing materials prior to installation in the office environ-
ment.
No. Content Method
1 Implements, facil-
ity, 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 condi-
tion.

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 LF mark shows 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.
