GENERAL PRECAUTIONS REGARDING THE INSTALLATION
AND SERVICE FOR THE COPIER e-STUDIO550/650/810
The installation and service should be done by a qualified service technician.
1. Transportation/Installation
· When transporting/installing the copier, move it by the casters while lifting the stoppers.
The copier is quite heavy and weighs approximately 200 kg (441 lb), therefore pay full attention
when handling it.
· Be sure to use a dedicated outlet with AC 115V or 120V/20A (220V, 230V, 240V/10A) or more
for its power source.
· The copier 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 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,
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. 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.
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 copier.
5. Disposition of Consumable Parts, Packing Materials, Used batteries and RAM-ICs
· Regarding the recovery and disposal of the copier, supplies, consumable parts, packing materials,
used batteries and RAM-ICs including litium batteries, 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 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 copier and
make sure that there are no uninsulated charged objects in the vicinity.
Caution : Dispose of used batteries and RAM-ICs including lithium batter-
ies according to this manual.
Attention : Se débarrasser de batteries et RAM-ICs usés y compris les batteries
en lithium selon ce manuel.
Vorsicht : Entsorgung des gebrauchten Batterien und RAM-ICs (inklusive
der Lithium-Batterie) nach diesem Handbuch.
