GENERAL PRECAUTIONS REGARDING THE INSTALLATION
AND SER VICE FOR THE COPIER DP4500/3500

The installation and service should be done by a qualified service technician.

1. T ransportation/Installation

• When transporting/installing the copier, employ two persons and be sure to use the positions as
indicated below .
The copier is quite heavy and weighs approximately 73kg (161lb), therefore pay full attention when
handling it.

• Be sure to use a dedicated outlet with AC 115V or 120V/15A (220V, 230V , 240V/10A) or more f or
its power source.

• The copier must be grounded for saf ety.
Never g round it to a gas pipe or a water pipe.

• Select a suitable place for installation.
Av oid excessive heat, high humidity, dust, vibration and direct sunlight.

• Also provide proper ventilation as the copier emits a slight amount of ozone .

• To insure adequate working space for the copying operation, keep a minimum clearance of
80 cm (32”) on the left, 80 cm (32”) on the right and 10 cm (4”) in the rear.

• The socket-outlet shall be installed near the copier and shall be easily accessible.

2. Service of Machines

• Basically, be sure to turn the main switch off and unplug the power cord during service.

• Be sure not to touch high-temperature sections such as the exposure lamp, the fuser unit, the
damp heater and their periphery.

• Be sure not to touch high-voltage sections such as the chargers, high-voltage transformer, IH
control circuit, exposure lamp control inverter, inverter for the LCD backlight and power supply
unit. Especially, the board of these components should not be touched since the electirc charge
may remain in the condensers, etc. on them even after the power is turned OFF.

• Be sure not to touch rotating/operating sections such as gears, belts, pulleys, fan, etc.

• Be careful when removing the covers since there might be the parts with very sharp edges under­neath.

• When servicing the machines with the main switch turned on, be sure not to touch live sections
and rotating/operating sections. Av oid exposure to laser radiation.

• Use suitable measuring instruments and tools.

• Av oid exposure to laser radiation during servicing.

− Av oid direct exposure to the beam.

− Do not insert tools, parts, etc. that are reflective into the path of the laser beam.

− Remove all watches, rings, bracelets , etc. that are reflective.

3. Main Service Parts for Safety

• The breaker , door switch, fuse, thermostat, thermofuse, thermistor, etc. are particularly important
for safety. Be sure to handle/install them properly.

4. Cautionary Labels

• During servicing, be sure to check the rating plate and the cautionary labels such as “Unplug the
power cord during service”, “Hot area”, “Laser w arning label” etc. to see if there is any dirt on their
surface and whether they are properly stuck to the copier.

5. Disposition of Consumable Parts/Packing Materials

• Regarding the recovery and disposal of the copier, supplies , consumable parts and packing mate­rials, it is recommended to follow the relevant local regulations or rules.

6. When parts are disassembled, reassembly is basically the reverse of disassembly unless
otherwise noted in this manual or other related documents. Be careful not to reassemble
small parts such as screws, washers, pins, E-rings, star washers in the wrong places.

7. Basically , the machine should not be operated with an y parts removed or disassembled.

8. Precautions Against Static Electricity

• The PC board must be stored in an anti-electrostatic bag and handled carefully using a wristband,

because the ICs on it may become damaged due to static electricity.

Caution: Before using the wristband, pull out the power cord plug of the copier and make

sure that there are no uninsulated charged objects in the vicinity .

Caution : Dispose of used batteries and RAM-ICs including lithium batteri es

according to the manufacturer’s instructions.

Attention : Se débarrasser de batteries et RAM-ICs usés y compris les batteries en

lithium selon les instructions du fabricant.

V orsic ht : Entsorgung des gebrauchten Batterien und RAM-ICs (inklusive

der Lithium-Batterie) nach Angaben des Herstellers.

DP4500/3500 ERROR CODES AND SELF-DIAGNOSIS

1.2 Self-Diagnosis Modes

Since this copier is designed to cope with multifunctions such as those of a network printer and DSS, there
are many setting items which are related to each other in the self-diagnosis modes.
Malfunctions such as machine locking can be caused by the internal structural problem of the program
when a normal operation is attempted by pressing [0] and [9] simultaneously or [C/S] on the control panel
subsequently to the adjustment.
Therefore, turn OFF the power after using the self-diagnosis mode for adjustment after unpacking, service
or prev entive maintenance , and then leav e the machine to the customer .
