GENERAL PRECAUTIONS REGARDING THE INSTALLATION AND

SERVICE FOR e-STUDIO161

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

1. Transportation/Installation

• When transporting/installing the machine, employ two persons and be sure to use the positions as indicated below. The machine is quite heavy and weighs approximately 30kg (14.3 lb.), therefore pay full attention when handling it.

• Be sure to use a dedicated outlet with AC 110A, 115V or 127V/10A, 220V-240V or 240V/5A) for its power source.

• The machine must be grounded for safety. Never ground it to a gas pipe or a water pipe.

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

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

• The socket-outlet shall be installed near the machine 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 and their periphery.

• Be sure not to touch high-voltage sections such as the chargers and the high-voltage transformer. Especially, the board of these components should not be touched since the electric charge may remain in the capacitors, 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. Avoid exposure to laser radiation.

• Use suitable measuring instruments and tools.

• Avoid exposure to laser radiation during servicing.

- Avoid 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.

• Unplug the power cable and clean the area around the prongs of the plug once a year or more. A fire may occur when dust lies on this area.

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. If these parts are shorted circuit and/or made

their functions out, they may burn down, for instance, and may result in fatal accidents. Do not allow

a short circuit to occur. Do not use the parts not recommended by Toshiba TEC Corporation.

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 warning label” etc. to see if there is any dirt on their

surface and whether they are properly stuck to the machine.

5. Disposition of Consumable Parts, Packing Materials

• Regarding the recovery and disposal of the machine, supplies, consumable parts, packing materials,

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 any 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 machine and make

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