Service Manual

 

* About a main unit illustration, it may differ from a target model.

* 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.

* There  is  a  high  temperature  area  inside  the  machine.  Use

extreme care when servicing.
It may cause a burn.

* There  is  a  high  voltage  section  inside  the  machine  which  may

cause an electric shock. Be careful when servicing.

* Do  not  disassemble  the  laser  unit.  Do  not  insert  a  reflective

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

* When  servicing  with  the  machine  operating,  be  careful  not  to

squeeze  you  hands  by  the  chain,  the  belt,  the  gear,  and  other
driving sections.

* Do not leave the machine with the cabinet disassembled.

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

* When servicing, do not breathe toner, developer, and ink exces-

sively. Do not get them in the eyes.
If  toner,  developer,  or  ink  enters  your  eyes,  wash  it  away  with
water immediately, and consult a doctor if necessary.

* The machine has got sharp edges inside. Be careful not to dam-

age fingers when servicing.

* Do not throw toner or a toner cartridge in a fire. Otherwise, toner

may ignite and burn you.

* When replacing a lithium battery on a PWB, only use the speci-

fied replacement battery.
If  a  battery  of  different  specification  is  used,  it  may  cause  a
machine malfunction or breakdown.

* When carrying a unit with PWB or electronic parts installed to it,

be sure to put it in an anti-static-electricity bag.
It may otherwise cause a machine breakdown or malfunction.

* Be  sure  to  connect  the  power  cord  only  to  a  power  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.

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

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

* 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,
grounding must be made.

* When connecting the grounding wire, never connect it to the fol-

lowing points.
- Gas tube
- Lightning conductor
-  A  water  pipe  or  a  water  faucet,  which  is  not  recognized  as  a

grounding object by the authorities.

- Grounding wire for telephone line

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

* Do not damage, break, or stress the power cord.

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

* 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.

* Do  not  place  liquids  or  foreign  metallic  objects  inside  the

machine.
It may cause a fire or an electric shock.

* Do not touch the power cord, insert the phone jack, operate the

machine,  or  perform  service  on  the  machine  with  wet  or  oily
hands.
It may cause an electric shock.

Do not install the machine at the following sites.
* Place of high temperature, high humidity, low temperature,

low humidity, place under an extreme change in temperature
and humidity.
Paper may get damp and form condensation inside the machine,
causing paper jam or copy dirt.
For  operating  and  storing  conditions,  refer  to  the  specifications
described later.

* Place of extreme vibrations

It may cause a breakdown.

* Poorly ventilated place

An electrostatic type copier will produce ozone.
The quantity of ozone produced is designed to a low level so as
not to affect human bodies. However, continuous use of such a
machine may produce an ozone smell. Install the machine in a
well ventilated place.
