DM-2000

A number of options are available for the DM System which allow you
to configure the system to meet your particular needs. The options in-
clude the following.

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

    WARNING: If this WARNING should be ignored, a serious danger

to life or a serial injury would be resulted.

    CAUTION: If this CAUTION should be ignored, an injury or a

damage to properties would be resulted.

  This pictograph means that a care must be taken. In the
pictograph, the concrete content is drawn. (High temperature
in this example)
  This pictograph means inhibition. The concrete content of
inhibition is shown in or near the pictograph. (Inhibition of dis-
assembly in this example)

●

This pictograph means a thing which must be done. (Dis-

connecting the power plug from the power outlet in this ex-
ample)

  1) Never use a power source of more than 15A, 100V.

Avoid complex wiring, which may lead to a fire or an electric
shock.

  2) When any abnormality occurs, such as smoke or bad smell, do not

use the machine. If used in abnormal conditions, a fire or an
electric shock may be resulted.

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

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

  4) When removing the cabinet of the machine, use an extreme care.

There is a high voltage section inside the machine which may

cause an electric shock when touched. Do not leave the machine
with the cabinet removed. It is very dangerous for the user to
touch the inside of the machine.

 5) Do not damage, brake, or work the power cord. Do not put a

heavy thing on the power cord. Do not pull or bend the power cord
extremely. Otherwise, the power cord may be damaged to cause
a fire or an electric shock.

  6) Do not put a vessel with water in it on the machine. Do not put a

metal piece on the machine, which may drop into the machine,
causing a fire or an electric shock.

  7) If water or a metal piece drops into the machine, turn off the power

switch, disconnect the power plug, then remove the dropped thing.

  8) Do not use a wet hand to disconnect or insert the power plug and

to operate or service the machine. It may cause an electric shock.

  1) Avoid installation on an unstable surface or a slant surface. Other-

wise, it may drop from the surface, resulting in an injury. It is ad-
visable to use the optional paper feed desk or the exclusive-use
desk.

  2) Avoid installation in a humid or dusty place. Otherwise, a fire or an

elctric shock may be resulted.

  3) The fusing section is very high. Be careful not to burn when ser-

vicing.

  4) When disconnecting the power plug from the power outlet, do not

pull the power cord. Otherwise, the cord may be damaged, result-
ing in exposed core or disconnection, causing a fire or an electric
shock.

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

may pop and burn you.

 6) When using the optional paper feed desk or the exclusive-use

desk, be sure to fix the adjusters on the floor, and lock the casters.
As shown in the figure, rotate the adjuster in the fixing direction
until it makes contact with the floor. Lock the casters to fix the
machine. (If the casters are not locked, the machine may gradually
move so that the SPF cable may be rubbed with the wall, causing
disconnection.

When moving the machine a little for reforming the office, turn the
adjuster to release lock of the casters. (After moving, lock the ad-
justers and casters to fix the machine.)

  7) Do not see the light source and the laser beams. Otherwise the

eyes may be damaged.

 8) When moving the machine, turn off the power switch and the

heater switch, and be sure to disconnect the power plug from the
power outlet. If not, the cord may be damaged to cause a fire or
an electric shock.

  9) It is very dangerous to perform reception or printing during servic-

ing. When servicing with the cabinet removed, pull out the
telephone line and the printer cable from the machine. (The laser
print function and the Fax function are options.)

10) There are some sharp edges inside the machine. Be careful not

to injure your fingers when servicing.
