SAFETY WARNINGS
[1] MODIFICATIONS NOT AUTHORIZED
BY Konica
Konica copiers are renowned for their high reliability.
This reliability is achieved through high-quality design
and a solid service network.
Photocopier design is a highly complicated and
delicate process where numerous mechanical,
physical, and electrical aspects have to be taken into
consideration, with the aim of arriving at proper
tolerances and safety factors. For this reason,
unauthorized modifications involve a high risk of
degrading performance and safety. Such
modifications are therefore strictly prohibited. The
points listed below are not exhaustive, but they
illustrate the reasoning behind this policy.
PROHIBITED ACTIONS :
(1) Using extension cables or a different power
cord than specified by Konica.
(2) Using other fuses than specified by Konica.
Safety will not be assured, leading to a risk of
fire and injury.
(3) Disabling fuses or bridging fuse terminals
with wire, metal clips, solder or similar. (This
applies also to thermal fuses.)
(4) Removing air filters (except for replacement).
(5) Disabling relay functions (such as wedging
paper between relay contacts, etc.).
(6) Disabling safety functions (interlocks, safety
circuits, etc.). Safety will not be assured,
leading to a risk of fire and injury.
(7) Performing actions to copier not described in
the instruction manual or the service
handbook.
(8) Using parts other than specified by Konica.
[2] CHECKPOINTS WHEN PERFORMING
ON-SITE SERVICE
Konica copiers are extensively tested before
shipping, to ensure that all applicable safety
standards are met, in order to protect the customer
and customer engineer from the risk of injury.
However, in daily use, any electrical equipment may
be subject to parts wear and eventual failure. In order
to maintain safety and reliability, the customer
engineer must perform regular safety checks.
1. Advance Preparation for Safety
Checks
CAUTION:
(1) Wear clothing that facilitates work and is
designed for safety.
(2) Carry out all procedures carefully to prevent
injury.
(3) Be sure to disconnect the power cord of the
copier and all optional equipment from the
AC outlet.
Simply turning off the power switch is not
sufficient, because paper feed units or other
electrical equipment may be powered also
when the power switch is turned off.
(4) Proceed with special care when performing
operation checks or adjustment while the
unit is powered. When carrying out operation
checks or adjustment while external covers
are removed, the risk of electrical shock
exists when touching parts which carry high
voltage or electrical charge. The risk of injury
exists when touching moving parts such as
gears or chains.

SAFETY AND IMPORTANT WARNING ITEMS
2. Safety Checkpoints
The following list is not exhaustive, but it includes
actions which must be carried out at every on-site
service.
CAUTION:
(1) Check external covers and the frame for
sharp edges, burrs, or nicks.
(2) Check external covers and hinges for
loosening or damage.
(3) Check wiring for squeezing or damage.
(4) Check power cord for insulation problems
(conductor must not be exposed).
(5) Check power cord and cable ties etc. for
loosening from frame.
WARNING:
(1) Verify that the copier is properly grounded. If
a problem is detected, establish a proper
ground connection.
(2) Connecting the ground lead to an improper
point such as listed below results in a risk of
explosion and electric shock.
Unsuitable ground points:
a. Gas pipe
b. Lightning rod
c. Telephone line ground
d. Plastic water pipe or water pipe or
faucet that has not been approved by
authorities for grounding use
3. Precautions for on-site service
CAUTION:
(1) Before performing safety check work, read all
relevant documentation (service handbook,
technical notices, etc.) and proceed accord-
ing to the prescribed procedure, using only
the prescribed tools. Do not carry out any
adjustments not described in the documen-
tation.
(2) If the power cord is damaged, replace it only
with the specified power cord. If the power
cord insulation has been damaged and there
are exposed sections, short-circuits and
overheating may occur, leading to a serious
fire risk.
(3) Do not route the power cord so that it can be
stepped on or pinched. Otherwise overheat-
ing may occur, leading to a serious fire risk.
(4) When disconnecting any cables, always
grasp the connector and not the cable
(especially in the case of AC and high-
voltage leads).
(5) Carefully remove all toner remnants from
electrical parts, electrodes, etc.
(6) Make sure that wiring cannot come into
contact with sharp edges, burrs, or other
pointed parts.
(7) Double-check to make sure that all screws,
components, wiring, connectors, etc. that
were removed for safety check maintenance
have been reinstalled in the original location.
(Pay special attention to forgotten connec-
tors, pinched cables, forgotten screws, etc.)
(8) When installation and preventive mainte-
nance, verify that the power cord has been
securely plugged into the AC outlet. Contact
problems may lead to increased resistance,
overheating, and the risk of fire.
WARNING:
(1) Before disassembling or adjusting the
optical unit or any parts that use a laser,
make sure that the power cord has been
disconnected.
(2) Do not remove the main cover of the write
unit. Direct exposure of the eye to laser
beams may lead to blindness.
(3) Do not turn the copier on while the write unit
is not installed in its normal position.

[3] HANDLING OF MATERIALS FOR
SERVICING
CAUTION: Drum cleaner (alcohol-based) and
roller cleaner (acetone-based) are
highly flammable and must be
handled with care. When using
these materials for cleaning of
copier parts, observe the
following precautions.
(1) Disconnect the power cord from the AC
outlet.
(2) Use only a small amount of cleaner at a time
and take care not to spill any liquid. If this
happens, immediately wipe it off.
(3) Perform cleaning only in an environment
where sufficient ventilation is assured.
Breathing large quantities of organic
solvents can lead to discomfort.
(4) Do not replace the cover or turn the unit on
before any solvent remnants on the cleaned
parts have fully evaporated.
CAUTION: Toner and developer are not
harmful substances, but care
must be taken not to breathe
excessive amounts or let the
substances come into contact
with eyes etc. If the substances
get in the eye, rinse it with plenty
of water immediately. When
symptoms are noticeable, consult
a physician.
[4] MEASURES TO TAKE IN CASE OF
AN ACCIDENT
(1) If an accident has occurred, the distributor who
has been notified first must immediately take
emergency measures to provide relief to affected
persons and to prevent further damage.
(2) If a report of a serious accident has been re-
ceived from a customer, an on-site evaluation
must be carried out quickly and Konica Corpora-
tion must be notified.
(3) To determine the cause of the accident, condi-
tions and materials must be recorded through di-
rect on-site checks, in accordance with instruc-
tions issued by Konica Corporation.
(4) For reports and measures concerning accidents,
consult your superior, and follow the regulations
set in "Standards for the Control Program for
Measures Against Electrical Equipment Acci-
dents".
[5] CONCLUSION
(1) Safety of users and customer engineers de-
pends highly on accurate maintenance and ad-
ministration. Therefore, safety can be main-
tained by the appropriate by the proper daily ser-
vice work conducted by the customer engineer.
(2) When performing service, each copier on the site
must be tested for safety. The customer engi-
neer must verify the safety of parts and ensure
appropriate management of the equipment.
