							GENERAL PRECAUTIONS REGARDING THE SERVICE FOR  
e-STUDIO200L/202L/230/232/280/282 SERIES
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 hold the posi-
tions as shown in the figure.
The equipment is quite heavy and weighs approximate ly 75 kg (165.34 lb.) therefore pay full 
attention 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 110 V /  13.2 A, 115 V or 127 V / 12 A, 220-240 V or 240 
V / 8 A for its power source.
- The equipment must be grounded for safety.
- Select a suitable place for installation. Avoid exc essive heat, high humidity, dust, vibration and 
direct sunlight.
- Provide proper ventilation since the equipment emi ts a slight amount of ozone.
- To insure adequate working space for the copying op eration, keep a minimum clearance of 80 
cm (32”) on the left, 80 cm (32”) on the right and  10 cm (4”) on the rear.
- The equipment shall be installed near the socket o utlet and shall be accessible.
- Be sure to fix and plug in the power cable securel y after the installation so that no one trips over 
it.

							2)General Precautions at Service 
- Be sure to turn the power OFF and unplug the power  cable during service (except for the service 
should be done with the power turned ON).
- Unplug the power cable and clean the area around t he prongs of the plug and socket outlet once 
a year or more. A fire may occur when dust lies on  this area.
- When the parts are disassembled, reassembly is the  reverse of disassembly unless otherwise 
noted in this manual or other related documents. Be  careful not to install small parts such as 
screws, washers, pins, E-rings, star washers in the  wrong places.
- Basically, the equipment should not be operated wit h any parts removed or disassembled.
- The PC board must be stored in an anti-electrostat ic bag and handled carefully using a wristband 
since the ICs on it may be damaged due to static el ectricity.
- Avoid expose to laser beam during service. This eq uipment uses a laser diode. Be sure not to 
expose your eyes to the laser beam. Do not insert r eflecting parts or tools such as a screwdriver 
on the laser beam path. Remove all reflecting metal s such as watches, rings, etc. before starting 
service.
- Be sure not to touch high-temperature sections such  as the exposure lamp, fuser unit, damp 
heater and areas around them.
- Be sure not to touch high-voltage sections such as  the chargers, developer, high-voltage trans-
former, exposure lamp control inverter, inverter fo r the LCD backlight and power supply unit. 
Especially, the board of these components should no t be touched since the electric charge may 
remain in the capacitors, etc. on them even after the  power is turned OFF.
- Make sure that the equipment will not operate befo re touching potentially dangerous places (e.g. 
rotating/operating sections such as gears, belts pu lleys, fans and laser beam exit of the laser 
optical unit).
- Be careful when removing the covers since there mi ght be the parts with very sharp edges 
underneath.
- When servicing the equipment with the power turned  ON, be sure not to touch live sections and 
rotating/operating sections. Avoid exposing your eye s to laser beam.
- Use designated jigs and tools.
- Use recommended measuring instruments or equivalen ts.
- Return the equipment to the original state and che ck the operation when the service is finished.
3) Important Service Parts for Safety
- The breaker, door switch, fuse, thermostat, thermo fuse, thermistor, IC-RAMs including lithium 
batteries, etc. are particularly important for safet y. Be sure to handle/install them properly. If 
these parts are short-circuited and their functions  become ineffective, they may result in fatal 
accidents such as burnout. Do not allow a short-cir cuit or do not use the parts not recommended 
by Toshiba TEC Corporation.
4) Cautionary Labels
- During servicing, be sure to check the rating plat e and cautionary labels such as “Unplug the 
power cable during service”, “CAUTION. HOT”, “CAUTI ON. HIGH VOLTAGE”, “CAUTION. 
LASER BEAM”, etc. to see if there is any dirt on th eir surface and if they are properly stuck to the 
equipment.
Caution: Before using the wristband, unplug the powe
r cable of the equipment and 
make sure that there are no charged objects which a re not insulated in the 
vicinity. 
						

							5)Disposal of the Equipment, Supplies, Packing Materi als, Used Batteries and IC-RAMs
- Regarding the recovery and disposal of the equipme nt, supplies, packing materials, used batter-
ies and IC-RAMs including lithium batteries, follow  the relevant local regulations or rules.
Caution:
Dispose of used batteries and IC-RAMs including lit hium batteries according to this manual.
Attention: Se débarrasser de batteries et IC-RAMs usés y compri s les batteries en lithium selon ce manuel.
Vorsicht: Entsorgung der gebrauchten Batterien und IC-RAMs (i nclusive der Lithium-Batterie) nach diesem Handbuch.
