Because of the possible hazards to an inexperienced
person servicing this equipment, as well as the risk of
damage to the equipment, Konica Business Technologies strongly recommends that all servicing be performed by Konica-trained service technicians only.
Changes may have been made to this equipment to
improve its performance after this service manual was
printed. Accordingly, Konica Business Technologies,
Inc., makes no representations or warranties, either
expressed or implied, that the information contained in
this service manual is complete or accurate. It is understood that the user of this manual must assume all risks
or personal injury and/or damage to the equipment while
servicing the equipment for which this service manual
is intended.
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!

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
Page 15
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 position is fixed; switching
between trays is accomplished by changing the
tray position up/down mechanism.
Tray up and down is done by the tray up/down
motor (M706), which the tray up/down wires to
drive the tray up or down.

*2 Prevention of tray up/down accident
To prevent the accident insertion of the hand into
the paper exit gate during tray motion up or down,
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.

MAIN BODY
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).
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.

*3 Paper stack
In the offset mode or staple mode, paper conveyed to the paper exit gate by the conveyance
rollers is then conveyed to the stack position by
paper exit roller/A running in reverse direction.
The conveyed paper is sent to the stopper by the
friction of the conveyance belt and stacked.
*4 Stapler unit shift
The stapler unit is driven by the stapler shift
motor; the stapler unit is fixed on the staple base
and moved by a belt along a rail. Owing to the
shape of the rail, when the stapler unit is moved to
either the forward or rear positions, the unit
rotates and it is possible to staple slantwise.
When the stapler is set to staple in two locations,
it moves to the first location, puts in the first
staple, then moves to the second location to put
in the second staple.

1.Operations
a.Normal alignment operation
The front and rear alignment plates work in
symmetry to the front and rear based on the center of
the alignment section, alternately aligning and
releasing. To create this symmetrical movement
the M703 and M704 always rotate in opposite
directions.
Every five sheets of the conveyed paper are aligned
and sent on to the paper exit section.
The timing of the M703 and M704 are set to the
starting point by the ON/OFF of the PS702 (paper
entrance detect PS).
b.Offset (shift alignment) operation
The sheets corresponding to odd sets of copies are
fed to the paper exit unit as soon as they have been
aligned normally. (Up to 5 sheets are stacked and
exited.)
During the alignment operation for even sets of
copies, M703 and M704 rotate in the same direction,
shifting the sheets forward from the center. The
aligned sheets are then sent to the paper exit unit.
(Up to 5 sheets are stacked and exited.
During sorting and stapling, paper exited by the
conveyance section is sent to the alignment section by the
M702 (paper exit motor) reverse direction, then aligned by
the alignment plates driven by the M703 (alignment motor,
(rear)) and the M704 (alignment motor, (front)).
The home position of the alignment plates is detected by
the PS709 (alignment plate detect PS (rear)) and the
PS710 (alignment plate detect PS (front)). The FS CB (FS
control board) controls the M702, M703 and M704. The
related signal are passed to the PS702 (paper entrance
detect PS).
c.Staple mode operation
In the staple mode, the M703 and M704 are
released after the stapling action is completed.
The ON/OFF timing of the M703 and M704 is set as
the M702 is turned from OFF to ON, and the PS702 is
turned OFF after the specified period of time.

Papers that have already been aligned or stapled are
exited by the paper exit roller.
A mechanical clutch is connected to M702 (paper exit
motor). A mechanical clutch can convey the forward
direction driving power to the exit roller with certain
movement.
The M702 is responsible for speed control for connection
with the mechanical clutch, for sending the alignment
section at the reversal rotation, and also during the usual
paper exit.
The M702 is controlled by the FS CB (FS control board).
The related signals are M707 (paper pressure motor),
M708 (stapler motor), PS701 (paper pressure PS), PS702
(paper entrance detect PS), PS703 (paper exit detect PS),
and PS707 (no paper detect PS).

1.Operation
During paper exit, both upper and lower exit rollers
are compressed as a consequence of the operation
performed by M707, and that condition is detected by
the ON/OFF state of PS701.
a.Non-staple mode operation
The ON/OFF timing of M702 is such that it turns ON
during the OFF of PS3, and turns OFF during the
OFF of PS702.
After the paper exit tray goes up until PS703 turns
ON, M706 moves the tray up and down in order to
keep the ON state of PS703 during paper exit.
b.Staple mode operation
M702 turns ON a certain time after M708 finishes the
stapling operation and turns OFF.
The subsequent operations are the same as for the
non-staple operation.

1.Operation
a.Up/down operation
When the tip of the paper turns PS702 ON, the tray is
driven down by a certain amount. After the rear of the
paper turns PS702 OFF, M706 turns ON driving the
tray up until PS703 is turned ON.
b.Full-stack detection operation
When a tray other than tray 1 is selected and PS703
is turned ON when PS704 is ON, the paper-full
condition is detected. When tray 1 is selected and
PS 703 is turned ON when PS706 is ON, the paperfull condition is detected.
c.Automatic tray switching operation
When tray 1, optional tray 1, and optional tray 2 are
selected and the paper-full condition is detected,
M706 drives the tray up so that PS703 is turned OFF
and then ON again, and the immediately lower tray is
set at the paper exit position.
When tray 2 is selected and the paper-full condition
is detected, M706 drives the tray down until PS716 is
turned ON, and then up until PS703 is turned ON, set
tray 1 at the paper exit position.

1.Operation
The stapler unit is usually at the home position of the
finisher.
When receiving a command signal from the main
unit, M705 moves the stapler unit to the stapling
position according to paper size and starts the
stapling operation.
After finishing the copy, M705 moves the stapler unit
to its home position.
The M705 OFF timing is controlled by the number of
driving steps after PS708 is turned OFF.

1.Operation
a.Stapler operation
After the aligning operation of the last paper, M707 is
turned ON and compresses the paper using the exit
rollers. Then, M708 is turned ON and stapling
begins.
When PS701 is turned OFF, M707 is turned OFF,
PS712 is turned ON, and M708 is turned OFF.
For continuous stapling, M705 is not turned ON, and
the stapler unit waits for the next stapling at the same
position.
In the case of 2 stapling positions, the first staple is
executed and then M705 moves the stapler to the
specified position for the second staple. M708 then
turns ON and executes the second staple. At this
moment, if continuous stapling has been selected,
the stapler unit stops at the immediately previous
stapling position. When the first stapling operation of
the next paper is done, M705 moves the stapler unit
for the second stapling operation.
After the copy is finished, the stapler unit returns to
its home position.
2.Signals
a.Input signals
(1) PS712 (PS712 -> FS CB)

[L]: Home position
[H]: Non-home position
(2) PS713 (PS713 -> FS CB)
No-staple detection signal of the stapler unit
[L]: With staple
[H]: No staple
(3) PS714 (PS714 -> FS CB)
Detects whether staple is in position for stapling by
stapler unit (whether staple is present at point just
ahead of where it is actually driven from the stapler).
[L]: With staple
[H]: No staple
b.No-staple detection control
The PS713 is equipped to detect the no-staple
condition of the stapler unit. When the staple is not
present, the LCD (display board) of the main unit
shows a message indicating the no-staple condition.
c.Stapler Initial Operation
After replacing the stapler cartridge, M708 is driven
until staples are detected in the PS714, performing
up to a maximum of 16 blank stapling operations,
then the staples are positioned just in front of the
stapling position.

How to use this catalog
This parts catalog includes illustrations and part numbers for all replacement 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 number 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.
