2.Precautions for Maintenance

WARNING

• Always remove the power plug from the wall outlet before starting machine disassembly. ...............

• Always follow the procedures for maintenance described in the service manual and other related 

brochures. .......................................................................................................................................

• Under no circumstances attempt to bypass or disable safety features including safety mechanisms 

and protective circuits. .....................................................................................................................

• Always use parts having the correct specifications. ..........................................................................
• Always use the thermostat or thermal fuse specified in the service manual or other related bro-

chure when replacing them. Using a piece of wire, for example, could lead to fire or other serious 
accident. ..........................................................................................................................................

• When the service manual or other serious brochure specifies a distance or gap for installation of a 

part, always use the correct scale and measure carefully. ................................................................

• Always check that the copier is correctly connected to an outlet with a ground connection. .............
• Check that the power cable covering is free of damage. Check that the power plug is dust-free. If it 

is dirty, clean it to remove the risk of fire or electric 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 high potentials and may cause electric 

shock if handled improperly. ............................................................................................................

CAUTION

• Wear safe clothing. If wearing loose clothing or accessories such as ties, make sure they are 

safely secured so they will not be caught in rotating sections. ..........................................................

• Use utmost caution when working on a powered machine. Keep away from chains and belts. ........

• Handle the fixing section with care to avoid burns as it can be extremely hot. ..................................
• Check that the fixing unit thermistor, heat and press rollers are clean. Dirt on them can cause 

abnormally high temperatures. ........................................................................................................
