2) General Precautions at Service- Be sure to turn the power OFF and unplug the power cable during service (except for the serviceshould be done with the power turned ON).- Unplug the power cable and clean the area around the prongs of the plug and socket outlet oncea 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 otherwisenoted in this manual or other related documents. Be careful not to install small parts such asscrews, 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 carefully using a wristbandsince the ICs on it may be damaged due to static electricity.- Avoid expose to laser beam during service. This equipment uses a laser diode. Be sure not toexpose your eyes to the laser beam. Do not insert reflecting parts or tools such as a screwdriveron the laser beam path. Remove all reflecting metals such as watches, rings, etc. before startingservice.- Be sure not to touch high-temperature sections such as the exposure lamp, fuser unit, dampheater 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 for the LCD backlight and power supply unit.Especially, the board of these components should not be touched since the electric charge mayremain in the capacitors, etc. on them even after the power 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 laseroptical unit).- Be careful when removing the covers since there might be the parts with very sharp edgesunderneath.- When servicing the equipment with the power turned ON, be sure not to touch live sections androtating/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 causemalfunctions.3) Important Service Parts for Safety- The breaker, door switch, fuse, thermostat, thermofuse, thermistor, batteries, IC-RAMs includinglithium 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 fatalaccidents such as burnout. Do not allow a short-circuit or do not use the parts not recommendedby Toshiba TEC Corporation.4) Cautionary Labels- During servicing, be sure to check the rating plate and cautionary labels such as “Unplug thepower 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 theequipment.Caution: Before using the wristband, unplug the power cable of the equipment andmake sure that there are no charged objects which are not insulated in thevicinity.06/09
