ATTENTION TO BE PAID DURING ASSEMBLY/DISASSEMBLY1.1 Safety CautionsElectrical shockIn order to prevent any risk of electrical shock, always be sure to check that the power cord and modular jackhave been removed. Also, remove all cables connecting to the computer. When conducting service thatrequires the main unit to be powered on, be sure to wear some kind of earthing, such as a wrist strap, etc.Otherwise, there is a danger of conduction and electrical shock.Parts which are generally likely to cause electrical shock are as follows.• Power supply unit primary (supplied with AC voltage)• Telephone line primary• LBP engine high voltage contacts (for high voltage during developing and transfer)High temperatureIn order to prevent burns during disassembly, allow at least ten minutes, after the power has been switchedoff, for the high temperature components to cool down.General high temperature components are as follows.• Motors• Power supply unit• Elements on driver ICs, etc., on PCBs (in particular, ICs with heatsinks)• BJ cartridge aluminium plate (for BJ cartridge engine models)• Fixing unit and peripheral covers (for LBP engines)Battery ReplacementThe batteries must be replaced correctly to avoid explosion. Do not replace any battery with one out indi-cated for the machine, ie., use one of the same type or equivalent. Be sure to dispose of used batteriesaccording to local laws and regulations.FireIt is dangerous to throw lithium batteries and parts and components containing flammable substances, suchas cartridges, etc., into fire. Such parts and components must be disposed of in accordance with local lawsand regulations.IgnitionWhen using solvents such as alcohol, etc., while conducting service, there is a danger of fire igniting fromheat from internal circuitry and from sparks. Before using any such solvents, be sure to switch off the powerand allow time for high temperature parts to cool down. Make sure that there is sufficient ventilation whenworking with solvents.Movable partsIn order to prevent accidents with movable parts, be sure to remove the power cable when conductingservice that requires disassembly. Also, take care that personal accessories and hair, etc., are not caught inany moving parts.
