SAFETY AND IMPORTANT WARNING ITEMS
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.
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 equip-
ment 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.
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.
[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.
WARNING:
(1) Verify that the copier is properly grounded. If a prob-
lem is detected, establish a proper ground connec-
tion.
(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:
- Gas pipe
- Lightning rod
- Telephone line ground
- Plastic water pipe or water pipe or faucet that has
not been approved by authorities for grounding use

SAFETY AND IMPORTANT WARNING ITEMS
3. Description of Safety Checks
CAUTION:
(1) Before performing safety check work, read all relevant
documentation (service handbook, technical notices,
etc.) and proceed according to the prescribed procedure, using only the prescribed tools. Do not carry out
any adjustments not described in the documentation.
(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, shortcircuits 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 overheating 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, compo-
nents, wiring, connectors, etc. that were removed for
safety check maintenance have been reinstalled in the
original location. (Pay special attention to forgotten
connectors, pinched cables, forgotten screws, etc.)
(8) When installation and preventive maintenance, 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 write 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.
(4) Danger of explosion if battery is incorrectly replaced,
replace only with the same or equivalent recommended
by the manufacturer. Discard used batteries according to the manufacture's instructions.

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 pre-
cautions.
(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 suffi-
cient 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 sub-
stances, but care must be taken not to
breathe excessive amounts or let the sub-
stances come into contact with eyes etc.
It may be stimulative. If the substances
get in the eye, rinse it with plenty of water
immediately. When symptoms are notice-
able, 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 received from a
customer, an on-site evaluation must be carried out quickly
and Konica Corporation must be notified.
(3) To determine the cause of the accident, conditions and
materials must be recorded through direct on-site checks,
in accordance with instructions 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 Accidents".
