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.
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 copiers have 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 copier 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 know what
General Safety Guidelines
This copier 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
copier 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 copier 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 broken).
• Inspect cables for wear, frays, or pinched areas.
v
SAFETY PRECAUTIONS
• Ensure that the power cord insulation is not damaged (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 copier
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 copier,
are directly dependent upon the conscientious effort
of each and every technician.
Remember...when performing service calls, use good
judgement (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 copier
as well as those who service the copier depend on it!

1. Paper conveyance
Paper conveyance is performed by the conveyance rollers A,
B, C and D, the intermediate roller, conveyance slide shaft and
subtray paper exit roller. These components are driven by
the 1st conveyance motor (M1) and the 2nd conveyance motor
(M4) through the timing belt.
Stacking to the paper stacker is performed by the stacker
entrance roller and sponge roller. These are driven by the
stacker entrance motor (M14) via the timing belt.
Paper exiting is performed by the stacker paper exit belt arm
and the paper exit rollers. These are driven by the paper exit
motor (M7) via the timing belt.

(3) Pressure of the paper exit roller
The paper exit roller rotation is slower than the conveyance rollers A, B and C. Therefore pressure is released at times other than when paper is exiting.
When the paper reaches the paper exit opening the
paper exit roller applies pressure and paper is exited
to the main tray . The pressing and releasing of paper is
performed by the paper exit opening solenoid (SD4).

6. Intermediate conveyance roller
In this machine, in order to be compatible with thick paper,
it has its pressure of the intermediate conveyance roller
set at a slightly higher level.
While in conveyance collectively of the 1st and 2nd copies
of the 2nd set and later to the stacker in staple copy mode
for small-sized paper, the decompression solenoid (SD3)
is operated to lower the pressure of the intermediate conveyance roller.
This is to prevent dirt from the roller from sticking to the
paper and wrinkles from taking place on paper in conveyance.
