GENERAL PRECAUTIONS REGARDING THE SERVICE FOR e-STUDI0520/523/600/603/720/723/850/853
The installation and Service should be done by a qualified Service technician.
1)Transportation/lnstallation - When transporting/installing the equipment, employ four persons and be sure to move it by the casters vvhile lifting the stoppers. The equipment is quite heavy and weighs approximately 210 kg (463 Ib), therefore pay full atten-tion when handling it. - Be sure not to hold the movable parts or units (e.g. the RADF) when transporting the equipment. - Be sure to use a dedicated outlet with AC 115 V /16 A, 127 V /16 A, 220 V or 220-240 V / 9 A for its power source. - The equipment must be grounded for satety. - Select a suitable place for installation. Avoid excessive heat, high humidity, dust, vibration and direct sunlight. - Provide proper ventilation since 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") on the rear. - The equipment shall be installed near the Socket outlet and shall be accessible. - Be sure to fix and plug in the power cable securely 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 povver cable and clean the area around the 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 othervvise noted in this manual or other related documents. Be careíul 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 with any parts removed or disassembled. - The PC board must be stored in an anti-electrostatic bag and handled careíully using a wristband since the ICs on it may be damaged due to static electricity. Caution: Betore using the wristband, unplug the power cable of the equipment and make sure that there are no charged objects which are not insulated in the vicinity. - Avoid expose to laser beam during Service. This equipment uses a laser diode. Be sure not to expose your eyes to the laser beam. Do not insert reflecting parts or tools such as a screwdriver on the laser beam path. Remove all reflecting metals 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, transfer belt, IH control Circuit, developer, 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 povver is turned OFF. - Make sure that the equipment will not operate before touching potentially dangerous places (e.g. rotating/operating sections such as gears, belts pulleys, fans and laser beam exit of the laser optical unit). - Be careíul when removing the covers since there might be the parts with very Sharp edges underneath.

07/11

- When servicing the equipment with the power turned ON, be sure not to touch live sections and rotating/operating sections. Avoid exposing your eyes to laser beam. - Use designated jigs and tools. - Use recommended measuring Instruments or equivalents. - Return the equipment to the original state and check the operation when the service is finished. - Be very careful to treat the touch panel gently and never hit it. Breaking the surface could cause malfunctions. 3)Important Service Parts for Safety - The breaker, door switch, fuse, thermostat, thermofuse, thermistor, batteries, IC-RAMs including lithium batteries, etc. are particularly important for safety. 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-circuit or do not use the parts not recommended by Toshiba TEC Corporation. 4)Cautionary Labels - During servicing, be sure to check the rating plate and cautionary labels such as "Unplug the power cable during Service", "CAUTION. HOT", "CAUTION. HIGH VOLTAGE", "CAUTION. LASER BEAM", etc. to see if there is any dirt on their surface and if they are properly stuck to the equipment. 5)Disposal of the Equipment, Supplies, Packing Materials, Used Batteries and IC-RAMs - Regarding the recovery and disposal of the equipment, supplies, packing materials, used batteries and IC-RAMs including lithium batteries, follow the relevant local regulations or rules.

Caution: Dispose of used batteries and IC-RAMs including lithium batteries according to this manual. Attention: Se débarrasser de batteries et IC-RAMs usés y compris les batteries en lithium selon ce manuel. Vorsicht: Entsorgung des gebrauchten Batterien und IC-RAMs (inclusive der Lithium-Batterie) nach diesem Handbuch.
