Safety precautions
This booklet provides safety warnings and precautions for our service
personnel to ensure the safety of their customers, their machines as well
as themselves during maintenance activities. Service personnel are
advised to read this booklet carefully to familiarize themselves with the
warnings and precautions described here before engaging in
maintenance activities.
Safety warnings and precautions
Various symbols are used to protect our service personnel and
customers from physical danger and to prevent damage to their
property. These symbols are described below:
DANGER: High risk of serious bodily injury or death may result from
insufficient attention to or incorrect compliance with warning
messages using this symbol.
WARNING: Serious bodily injury or death may result from insufficient
attention to or incorrect compliance with warning messages
using this symbol.
CAUTION: Bodily injury or damage to property may result from
insufficient attention to or incorrect compliance with warning
messages using this symbol.
Symbols
The triangle (
) symbol indicates a warning including danger
and caution. The specific point of attention is shown inside
the symbol.

indicates a prohibited action. The specific prohibition is
shown inside the symbol.
General prohibited action.
Disassembly prohibited.
indicates that action is required. The specific action
required is shown inside the symbol.
General action required.
Remove the power plug from the wall outlet.
Always ground the copier.
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 electric
shock. When using an extension cable, always check that it is
adequate for the rated current. ...............................................................
• Connect the ground wire to a suitable grounding point. Not grounding
the copier may cause fire or electric shock. Connecting the earth wire
to an object not approved for the purpose may cause explosion or
electric shock. Never connect the ground cable to any of the following:
gas pipes, lightning rods, ground cables for telephone lines and water
pipes or faucets not approved by the proper authorities. ........................
CAUTION
• Do not place the copier on an infirm or angled surface: the copier may
tip over, causing injury. ...........................................................................
• Do not install the copier in a humid or dusty place. This may cause fire
or electric shock. .....................................................................................
• Do not install the copier near a radiator, heater, other heat source or
near flammable material. This may cause fire. .......................................
• Allow sufficient space around the copier to allow the ventilation grills to
keep the machine as cool as possible. Insufficient ventilation may
cause 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 or
topple, leading to injury. ..........................................................................
• Avoid inhaling toner or developer excessively. Protect the eyes. If toner
or developer is accidentally ingested, drink a lot of water to dilute it in
the stomach and obtain medical attention immediately. If it gets into the
eyes, rinse immediately with copious amounts of water and obtain
medical attention. ....................................................................................
• Advice customers that they must always follow the safety warnings and
precautions in the copier’s instruction handbook. ...................................
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 brochure 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. Avoid wearing loose clothing or accessories such
as ties which may 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. .........................
• Do not remove the ozone filter, if any, from the copier except for
routine replacement. ...............................................................................
• Do not pull on the AC power cord or connector wires on high-voltage
components when removing them; always hold the plug itself. ..............
• Do not route the power cable where it may be stood on or trapped. If
necessary, protect it with a cable cover or other appropriate item. ........
• Treat the ends of the wire carefully when installing a new charger wire
to avoid electric leaks. ............................................................................
• Remove toner completely from electronic components. .........................
• Run wire harnesses carefully so that wires will not be trapped or
damaged. ................................................................................................
• After maintenance, always check that all the parts, screws, connectors
and wires that were removed, have been refitted correctly. Special
attention should be paid to any forgotten connector, trapped wire and
missing screws. ......................................................................................
• Check that all the caution labels that should be present on the machine
according to the instruction handbook are clean and not peeling.
Replace with new ones if necessary. ......................................................
• Handle greases and solvents with care by following the instructions
below: .....................................................................................................
· 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 cause
sparks when exposed directly to fire in a furnace, etc. .........................
• Should smoke be seen coming from the copier, remove the power
plug from the wall outlet immediately. ..................................................
3. Miscellaneous
WARNING
• Never attempt to heat the drum or expose it to any organic solvents
such as alcohol, other than the specified refiner; it may generate toxic
gas. .........................................................................................................
