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!

PAPER CONVEYANCE PATH
In the finisher, two different paper conveyance paths are
used, changing by the mode selected.
Straight Mode
In this mode, paper conveyed to the finisher is exited
straight into the tray. (For small size paper, the
operation of OffsetMode/Stapling Mode takes place,
even in the straight paper exit mode.)
6
Offset Mode/Staple Mode
In the offset mode or staple mode, paper conveyed
to the finisher is stacked once by the reverse
rotation of the exit roller. In the offset mode, this
stacked paper is offset by the paper alignment
plates. In the staple mode, the paper is stapled. When
the respective process is finished, the paper is exited
to the tray by the exit roller.

the paper exit gate is equipped with a shutter. The
shutter is driven by the reverse motion of the
paper pressure motor (M707), closing the paper
exit gate when the tray is in motion.

Conveyance is accomplished by the drive force of the
M701 (paper conveyance motor), which is transmitted to
the conveyance rollers. The M701 is linked with the main
body, so that rotation is set to low or high speed according
to the conveyance movement during copying.
The M701 is controlled by the FS CB (FS control board).
Related signals are provided by the PS702 (paper
entrance detect PS), PS717 (conveyance cover open/
close detect PS) and the MS701 (front door switch) and
PS3 (paper exit PS) of the main body.
1. Operation
As paper passes by the PS3 of the main body, the
M701 conveys the paper at a low speed in relation
with the paper exit velocity of the main body. When
the end of the paper passes through the PS3, the
M701 then conveys the paper at high speed. The
M701 again changes to low speed after the specified
period of time when the end of the paper passes
through the PS702, ready to convey the next sheet of
paper.

The paper exit position of the FS is fixed, the selected tray
is elevated or lowered to the paper exit position. Control of
the tray up/down is by the M706 (tray up/down motor)
which drives wires which is connected to and moves the
trays up and down.
The M706 is controlled by the FS CB (FS control board).
Related signals are provided by the PS703 (paper exit
detect PS), PS706 (tray lower limit detect PS), PS716
(tray count PS) and the MS702 (shutter switch).

1. Operations
a. Tray lower limit detection operation
With the sub power swich turnd ON, and the PS706
OFF, the M706 is reversed and the tray is lowered
until the PS706 is turned ON.
b. Tray count operation
One, two, or no optional trays can be installed.
If PS716 goes OFF after the low limit of the tray has
been detected, the machine judges that no optional
trays are installed.
When PS716 is ON, optional tray 1 is in place; in this
condition the M706 rotates normally, raising the tray
one step up until PS716’s detection position where
motion is stopped. Whether PS716 is ON or OFF at
this point determines whether optional tray 2 is in
place or not.
The number of trays is counted by means of a series
of operations.
After the tray count, the default tray that was set in the
key operator mode is set in the exit position.
c. Tray movement operation
If the exit tray has been selected at the LCD, then
when copying starts M706 turns ON and moves the
selected tray so that it sets into the exit position.
The number of times PS703 switches ON and OFF
sets the selected tray into the paper exit position.
d. Shutter switch operation
While the tray is in motion, the shutter, which
prevents the fingers or foreign objects from entering
the paper exit gate, is closed, with MS702 in the ON
position supplying 24VDC to the various loads.
While the tray is being raised or lowered the shutter
is opened and MS702 is OFF, interrupting the flow of
electricity and halting the motion of the FS.
