1. Installation Precautions
WARNING
• Do not use a power supply with a voltage other than that specified.Avoid multiple connections to one outlet: they may cause fire or electricshock. When using an extension cable, always check that it isadequate for the rated current. ...............................................................
• Connect the ground wire to a suitable grounding point. Not groundingthe copier may cause fire or electric shock. Connecting the earth wireto an object not approved for the purpose may cause explosion orelectric shock. Never connect the ground cable to any of the following:gas pipes, lightning rods, ground cables for telephone lines and waterpipes or faucets not approved by the proper authorities. ........................
CAUTION:
• Do not place the copier on an infirm or angled surface: the copier maytip over, causing injury. ...........................................................................
• Do not install the copier in a humid or dusty place. This may cause fireor electric shock. .....................................................................................
• Do not install the copier near a radiator, heater, other heat source ornear flammable material. This may cause fire. .......................................
• Allow sufficient space around the copier to allow the ventilation grills tokeep the machine as cool as possible. Insufficient ventilation maycause heat buildup and poor copying performance. ...............................
• Always handle the machine by the correct locations when moving it. ....
• Always use anti-toppling and locking devices on copiers so equipped.Failure to do this may cause the copier to move unexpectedly ortopple, leading to injury. ..........................................................................
• Avoid inhaling toner or developer excessively. Protect the eyes. If toneror developer is accidentally ingested, drink a lot of water to dilute it inthe stomach and obtain medical attention immediately. If it gets into theeyes, rinse immediately with copious amounts of water and obtainmedical attention. ....................................................................................
• Advice customers that they must always follow the safety warnings andprecautions in the copier’s instruction handbook. ...................................
2. Precautions for Maintenance
WARNING
• Always remove the power plug from the wall outlet before startingmachine disassembly. ............................................................................
• Always follow the procedures for maintenance described in the servicemanual and other related brochures. ......................................................
• Under no circumstances attempt to bypass or disable safety featuresincluding safety mechanisms and protective circuits. .............................
• Always use parts having the correct specifications. ...............................
• Always use the thermostat or thermal fuse specified in the servicemanual or other related brochure when replacing them. Using a pieceof wire, for example, could lead to fire or other serious accident. ...........
• When the service manual or other serious brochure specifies adistance or gap for installation of a part, always use the correct scaleand measure carefully. ...........................................................................
• Always check that the copier is correctly connected to an outlet with aground connection. .................................................................................
• Check that the power cable covering is free of damage. Check that thepower plug is dust-free. If it is dirty, clean it to remove the risk of fire orelectric shock. .........................................................................................
• Never attempt to disassemble the optical unit in machines using lasers.Leaking laser light may damage eyesight. ..............................................
• Handle the charger sections with care. They are charged to highpotentials and may cause electric shock if handled improperly. .............
CAUTION
• Wear safe clothing. If wearing loose clothing or accessories such asties, make sure they are safely secured so they will not be caught inrotating sections. .....................................................................................
• Use utmost caution when working on a powered machine. Keep awayfrom chains and belts. .............................................................................
• Handle the fixing section with care to avoid burns as it can beextremely hot. .........................................................................................
• Check that the fixing unit thermistor, heat and press rollers are clean.Dirt on them can cause abnormally high temperatures. .........................
• Do not remove the ozone filter, if any, from the copier except forroutine replacement. ...............................................................................
• Do not pull on the AC power cord or connector wires on high-voltagecomponents when removing them; always hold the plug itself. ..............
• Do not route the power cable where it may be stood on or trapped. Ifnecessary, protect it with a cable cover or other appropriate item. ........
• Treat the ends of the wire carefully when installing a new charger wireto avoid electric leaks. ............................................................................
• Remove toner completely from electronic components. .........................
• Run wire harnesses carefully so that wires will not be trapped ordamaged. ................................................................................................
• After maintenance, always check that all the parts, screws, connectorsand wires that were removed, have been refitted correctly. Specialattention should be paid to any forgotten connector, trapped wire andmissing screws. ......................................................................................
• Check that all the caution labels that should be present on the machineaccording to the instruction handbook are clean and not peeling.Replace with new ones if necessary. ......................................................
• Handle greases and solvents with care by following the instructionsbelow: .....................................................................................................· Use only a small amount of solvent at a time, being careful not to
spill. Wipe spills off completely.· Ventilate the room well while using grease or solvents.· Allow applied solvents to evaporate completely before refitting the
covers or turning the main switch on.· Always wash hands afterwards.
• Never dispose of toner or toner bottles in fire. Toner may causesparks when exposed directly to fire in a furnace, etc. .........................
• Should smoke be seen coming from the copier, remove the powerplug from the wall outlet immediately. ..................................................
