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
Page 8
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!

(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.

Paper is fed to the main tray via the stacker. At this time,
the paper passes the subtray gate, gate, and the bypass
gate as its conveyance path. Among these gates, the subtray gate is installed so that the stacker side becomes the
conveyance path beforehand, thus SD2 does not operate.
(1) SD1 (gate) ON timing
SD1 goes ON by the ON signal of the start button,
switches the gate to the stacker side, and enter a
standby mode for paper conveyance.
(2)
Paper conveyance for paper in sizes other than
8.5x11/8.5x5.5
Paper in sizes other than 8.5x11/8.5x5.5 is conveyed
to the stacker side by the gate. At this time, SD5 does
not operate and the paper is fed to the stacker
entrance roller.
(3) 8.5x1 1/8.5x5.5 sized paper conveyance (Conveyance
of the 1st copy of the 2nd and later batches)
For conveyance of 8.5x11 or 8.5x5.5 sized paper, in
the specified time after the trailing edge of the final
copy of the preceding set is detected by PS4 (FIN
entrance path), SD5 is turned ON, switching the
bypass gate into bypass. The 1st copy of the following
set is, therefore, guided into the bypass track.
(4) 8.5x1 1/8.5x5.5 sized paper conveyance (Conveyance
of the 2nd copy of the 2nd and later sets)
In the specified time after the trailing edge of the 1st
copy is detected by PS4, SD5 turns OFF, closing the
bypass gate.
The 2nd copy, therefore, follows the normal course,
which is conveyed to the stacker entrance roller together with the 1st copy held in the bypass track.
The 3rd copy and later are conveyed to the stacker in
the normal course, where SD5 never turns ON.

that the shift unit side becomes the conveyance path during idling state, so SD2 (subtray paper exit) and SD1 (gate)
which drive each gate do not operate.

8.5x1 1/8.5x5.5 sized sheets of paper for the 1st batch
to staple are fed in the same way as those other than
8.5x11/8.5x5.5sized.
(2) Paper conveyance of the 1st copy of the 2nd and
later sets
M14 turns OFF in the specified time after the trailing
edge of this paper is detected by PS4 (FIN entrance
path). The 1st copy, therefore, is held in standby in
the bypass track so that paper of the 2nd set is not
conveyed to the stacker section before completing to
staple the first set.
(3) Paper conveyance of the 2nd copy of the 2nd and later
sets
M14 turns ON again in low speed in the specified time
after the trailing edge of this paper is detected by PS4.
Therefore, the 1st and 2nd copies are collectively conveyed to the stacker section as being piled up. In the
specified time after PS5 (stacker conveyance path)
detects the trailing edges of the 1st/2nd copies, M14
changes into high speed rotation, entering standby
state for conveyance of the following copy.
The 3rd and later copies are conveyed to the stacker

Paper shift for sort and group modes is performed by M2
(roller shift). The control of M2 is performed by the FNS CB
(FNS control board).
1. Operation
In the specified time after the trailing edge of the paper
subject to shifting is detected by PS4 (FIN entrance path)
in Sort/Group mode, M2 (roller shift) turns ON.
Rotation of M2 starts shifting of the conveyance slide shaft.
The conveyance slide shaft is rotated by M4 (2nd conveyance) driving, which shifts as conveying paper.
When PS18 (roller shift HP) turns ON and detects completion of shifting of the conveyance slide shaft, M2 turns OFF
and is brought to a stop.
In the specified time from turning OFF of PS4, M2 turns ON
once again, returning the conveyance slide shaft to the
original position. When PS18 turns OFF and the conveyance slide shaft returns fully to the original position, M2 is
brought to a stop, where it waits for the next paper subject
to shifting.
Through repetition of these operations, sheets of paper are
shifted and conveyed to the paper exit roller.

M11 (stapler movement) and M12 (stapler rotation) move the
stapler to the fixed position corresponding to the stapler mode,
and paper is stapled by the rotation of M9/M10 (stapler R/F).
PS15 (stapler R HP) and PS17 (stapler F HP) switch ON-OFFON, and detect one cycle of the stapler movement. These are
controlled by the FNS CB (FNS control board).
1. Operation
a. Stapler one position movement control
Step motor M11 (stapler movement) turns ON by the ON
signal from the main body start button and the stapler is
moved to the fixed position that differs depending on paper
size and then stops. When the staple one position mode is
complete, M11 (stapler movement) moves the stapler and
it stops in the PS11 (stapler movement HP) ON position
(inside most).
38
Page 47
FS-106
b. Stapler two position movement control
Through the ON signal from the main body start button the
stapler is rotated by M12 (stapler rotation) so that the
stapler is parallel to the paper and then stops. At this time,
PS22 (stapler rotation HP2) is ON. When the stapler two
position mode is complete, M12 (stapler rotation) rotates
the stapler and it stops in the PS21 (stapler rotation HP1)
ON position (diagonal position).
c. Stapler movement control
Once the alignment plate is closed, M9 (stapler R)/M10
(stapler F) rotate and the staple push out plate drives the
staples in. When PS15 (stapler R HP) and PS17 (stapler F
HP) detects the home position (OFF/ON) and M9/M10
stop.
While the stapler is stapling, if within 500 ms from when
PS15/PS17 turn OFF they do not come ON again it is
judged as a staple jam. When the door is opened and
closed, M9/M10 rotate in reverse and return to the home
position (PS15/PS17 turn ON).
d. No staple detection control
PS14 (stapler R no staples) and PS16 (stapler F no staples)
detect that there are no staples in the staple cartridge.
After supplying the staples, M9/M10 rotates until PS24
(stapler R ready) / PS25 (stapler F ready) goes ON by the
staple, and prevents miss stapling.

How to use this catalog
This parts catalog includes illustrations and part numbers for all replace-
ment parts and assemblies used in this model.
Model-specific parts are identified in the illustrations with reference
numbers. Use the reference number to locate the corresponding part
number on the facing page.
Common hardware items, such as screws, nuts, washers, and pins,
are identified in the illustrations with reference letters. Use the reference
letter to locate the corresponding part number on the hardware listing in
the lower right hand corner of the facing page.
If you know a part number, but don’t know where the part is used, use
the numerical index to determine the page number and reference num-
ber for that part. Because some common parts are used in several
places, there may be more than one entry. Refer to the illustrations to
see where the part may be used.
If you know a part’s description, but don’t know where to look to find
the part number, use the alphabetical index to determine likely page and
reference numbers. Then look at the illustrations to determine that you
have identified the correct part. Locate the part number using the listing
on the opposite page.
Retail pricing that appears with the numerical index, while valid when
this catalog was printed, is subject to change without notice. The prices
are only suggested prices and are provided only for reference. Dealers
may determine their own selling prices. For up-to-date pricing, refer to
current Konica price lists or contact the Konica Parts Distribution Center.
How to order parts
Use standard Konica parts ordering procedures to obtain these parts.
For ordering options, contact Konica’s Parts Distribution Center.
When ordering parts, be sure to specify part numbers exactly as listed in
this catalog.
NOTE: Electrical parts may include previously used components.
