GENERAL PRECAUTIONS REGARDING THE INSTALLATION
AND SERVICE FOR e-STUDIO350/352/450/452
The installation and service should be done by a qualified service
technician.
1) Transportation / Installation
- When transporting/installing the equipment, employ two persons and be sure to use the positions
as indicated below.
The equipment is quite heavy and weighs approximately 83kg (182.98 lb.): e-STUDIO350/450 /
86kg (189.59 lb.): e-STUDIO352/452 therefore pay fullattention when handling it.
- Be sure not to hold the movable parts or units (e.g. the control panel, ADU or RADF) when trans-
porting the equipment.
- Be sure to use a dedicated outlet with AC 110V/13.2A, 115V or 127V / 12A, 220-240V or 240V /
8A for its power source.
- The equipment 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 equipment 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 equipment and shall be easily accessible.
- Be sure to fix and plug in the power cable securely after the installation so that no one trips over
it.

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, developer, IH control circuit,
high-voltage transformer, 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
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 power 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 Corpora-
tion.
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 equipment.
5) Disposition of Consumable Parts, Packing Materials, Used batteries and RAM-ICs
- Regarding the recovery and disposal of the equipment, supplies, consumable parts, packing
materials, used batteries and RAM-ICs including lithium batteries, follow the relevant local regu-
lations 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 wrist-
band, 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 equipment and
make sure that there are no uninsulated charged objects in the vicinity.
Caution:
Dispose of used batteries and RAM-ICs including lithium batteries according to this manual.
Attention:
Se débarrasser de batteries et RAM-ICs usés y compris les batteries en lithium selon ce manuel.
Vorsicht:
Entsorgung der gebrauchten Batterien und RAM-ICs (inklusive der Lithium-Batterie) nach diesem Handbuch.
