SAFETY PRECAUTIONS
SAFETY PRECAUTIONS
Installation Environment
Safety considerations usually are directed toward
machine design and the possibility of human error. In
addition, the environment in which a machine is operated must not be overlooked as a potential safety
hazard.
Most electrical equipment is safe when installed in a
normal environment. However, if the environment is
different from what most people consider to be normal, it is conceivable that the combination of the
machine and the room air could present a hazardous
combination. This is because heat (such as from
fusing units) and electrical arcs (which can occur
inside switches) have the ability to ignite flammable
substances, including air.
When installing a machine, check to see if there
is anything nearby which suggests that a potential hazard might exist. For example, a laboratory
might use organic compounds which, when they
evaporate, make the room air volatile. Potentially dangerous conditions might be seen or smelled. The
presence of substances such as cleaners, paint thinners, gasoline, alcohol, solvents, explosives, or similar items should be cause for concern.
If conditions such as these exist, take appropriate
action, such as one of the following suggestions.
know what effect may be caused by altering any
aspect of the machine’s design. Such changes have
the potential of degrading product performance and
reducing safety margins.
For these reasons, installation of any modification not
specifically authorized by Konica Business Machines
U.S.A., Inc., is strictly prohibited.
The following list of prohibited actions is not all-inclusive, but demonstrates the intent of this policy.
• Using an extension cord or any unauthorized
power cord adapter.
• Installing any fuse whose rating and physical size
differs from that originally installed.
• Using wire, paper clips, solder, etc., to replace or
eliminate any fuse (including temperature fuses).
• Removing (except for replacement) any air filter.
• Defeating the operation of relays by any means
(such as wedging paper between contacts).
• Causing the machine to operate in a fashion other
than as it was designed.
• Making any change which might have a chance
of defeating built-in safety features.
• Using any unspecified replacement parts.
• Determine that the environment is controlled
(such as through the use of an exhaust hood) so
that an offending substance or its fumes cannot
reach the machine.
• Remove the offending substance.
• Install the machine in a different location.
The specific remedy will vary from site to site, but the
principles remain the same. To avoid the risk of injury
or damage, be alert for changes in the environment
when performing subsequent service on any machine, and take appropriate action.
Unauthorized Modifications
Konica equipment has gained a reputation for being
reliable products. This has been attained by a combination of outstanding design and a knowledgeable
service force.
The design of the equipment is extremely important.
It is the design process that determines tolerances
and safety margins for mechanical, electrical, and
electronic aspects. It is not reasonable to expect
individuals not involved in product engineering to
General Safety Guidelines
This equipment has been examined in accordance
with the laws pertaining to various product safety
regulations prior to leaving the manufacturing facility
to protect the operators and service personnel from
injury. However, as with any operating device, components will break down through the wear-and-tear of
everyday use, as will additional safety discrepancies
be discovered. For this reason, it is important that the
technician periodically performs safety checks on the
equipment to maintain optimum reliability and safety.
The following checks, not all-inclusive, should be
made during each service call:
CAUTION: Avoid injury. Ensure that the equipment is
disconnected from its power source before continuing.
• Look for sharp edges, burrs, and damage on all
external covers and copier frame.
• Inspect all cover hinges for wear (loose or bro-
ken).
• Inspect cables for wear, frays, or pinched areas.
vii
SAFETY PRECAUTIONS
• Ensure that the power cord insulation is not dam-
aged (no exposed electrical conductors).
• Ensure that the power cord is properly mounted
to the frame by cord clamps.
• Check the continuity from the round lug (GND) of
the power cord to the frame of the copier -- ensure
continuity. An improperly grounded machine can
cause an electrically-charged machine frame.
Safeguards During Service Calls
Confirm that all screws, parts, and wiring which are
removed during maintenance are installed in their
original positions.
• When disconnecting connectors, do not pull the
wiring, particularly on AC line wiring and high
voltage parts.
• Do not route the power cord where it is likely to
be stepped on or crushed.
• Carefully remove all toner and dirt adhering to any
electrical units or electrodes.
• After part replacement or repair work, route the
wiring in such a way that it does not contact any
burrs or sharp edges.
• Do not make any adjustments outside of the
specified range.
Applying Isopropyl Alcohol
Care should be exercised when using isopropyl alcohol, due to its flammability. When using alcohol to
clean parts, observe the following precautions:
• Remove power from the equipment.
• Use alcohol in small quantities to avoid spillage
or puddling. Any spillage should be cleaned up
with rags and disposed of properly.
• Be sure that there is adequate ventilation.
• Allow a surface which has been in contact with
alcohol to dry for a few minutes to ensure that the
alcohol has evaporated completely before applying power or installing covers.
Summary
It is the responsibility of every technician to use professional skills when servicing Konica products. There
are no short cuts to high-quality service. Each piece
of equipment must be thoroughly inspected with respect to safety considerations as part of every routine
service call. The operability of the copier, and more
importantly, the safety of those who operate or service
the equipment, are directly dependent upon the conscientious effort of each and every technician.
Remember...when performing service calls, use good
judgment (have a watchful eye) to identify safety
hazards or potential safety hazards that may be present, and correct these problem areas as they are
identified -- the safety of those who operate the equipment as well as those who service the copier depend
on it!
