Service Manual

 

This Service Manual uses some symbols to assure safe operation.
Please understand the meanings of photographs before servicing.

1) When servicing, disconnect the power plug, the printer cable,

the  network  cable,  and  the  telephone  line  from  the  machine,
except when performing the communication test, etc.
It may cause an injury or an electric shock.

2) There  is  a  high  temperature  area  inside  the  machine.  Use

extreme care when servicing.
It may cause a burn.

3) There is a high voltage section inside the machine which may

cause an electric shock. Be careful when servicing.

4) Do  not  disassemble  the  laser  unit.  Do  not  insert  a  reflective

material such as a screwdriver in the laser beam path.
It may damage the eyes by reflection of laser beams.

5) When  servicing  the  machine  while  it  is  operating,  be  careful

when working around chains, belts, gears and drive sections.

6) Do not leave the machine with the cabinet disassembled.

Do not allow any person other than a serviceman access to the
inside of the machine. It may cause an electric shock, a burn,
or an injury.

7) When servicing, do not breathe toner or developer or get toner

or developer in the eyes. If toner or developer contact the eyes,
wash eyes immediately and contact a doctor if necessary.

8) The interior of the machine has sharp edges.   Be careful when

servicing the machine, to avoid contact with these edges.

9) Do not throw toner or a toner cartridge in a fire. Toner is com-

bustible and may explode and burn you.

10) When replacing the lithium battery on the PWB, only use the

specified battery.
If a battery of different specification is used, it may not be com-
patible and cause breakdown or malfunction of the machine.

11) When  carrying  a  PWB,  be  sure  to  transport  the  PWB  in  an

anti-static bag.Failure to do so may cause malfunction or fail-
ure of the PWB.

1) Be sure to only connect  the power cord to an outlet that meets

the specified voltage and current requirements. Avoid complex
wiring which may lead to a fire or an electric shock.
It may cause a fire or an electric shock.

2) If  there  is  any  abnormality  such  as  a  smoke  or  an  abnormal

smell, interrupt the job and disconnect the power cord.
It may cause a fire or an electric shock.

3) Be sure to connect the grounding wire. If an electric leakage

occurs  without  grounding,  a  fire  or  an  electric  shock  may
result.
To  protect  the  machine  and  the  power  unit  from  lightening,
proper grounding must be made.

4) When  connecting  the grounding  wire, never connect it  to the

following points.
It may cause an explosion, a fire or an electric shock.

• Gas tube
• Lightning conductor
• A water pipe or a water faucet.
• Grounding wire for telephone line

5)

Do not damage, break, or stress the power cord.
Do not put heavy objects on the power cable. Do not forcibly
bend or pull the power cable.
It may cause a fire or an electric shock.

6)

Keep the power cable away from a heat source.
Do not insert the power plug with dust on it into a power outlet.
It may cause a fire or an electric shock.

7)

Do not put any foreign liquid or metal piece (that may fall into
or spill) inside of the machine.
It may cause a fire or an electric shock.

8)

Do  not  touch  the  power  plug,  insert  a  telephone  line  jack  or
network  jack,  operate  the  machine,  or  service  the  machine
with wet or oily hands.
It may cause an electric shock.

Do not install the machine at the following sites.
1)

Places  of  high  temperature,  high  humidity,  low  tempera-
ture, low humidity, places of extreme change in tempera-
ture and humidity.
Paper  may  get  damp  and  form  moisture  inside  the  machine,
causing paper jam or poor copy quality.
For operating and storing conditions, refer to the specifications
described later.

2)

Place of high vibrations
It may cause a breakdown.
