SAFETY WARNINGS

[1] Modifications Not Authorized by

Konica Minolta

Konica Minolta equipment is renowned for their high
reliability. This reliability is achieved through high-quality
design and a solid service network.

Unauthorized modifications involve a high risk of degrad­ing performance and safety. Such modifications are there­fore strictly prohibited. The points listed below are not
exhaustive, but they illustrate the reasoning behind this
policy.

PROHIBITED ACTIONS :

(1) Using extension cables or a different power cord

than specified by Konica Minolta.

(2) Using other fuses than specified by Konica

Minolta. Safety will not be assured, leading to a
risk of fire and injury.

(3) Disabling fuses or bridging fuse terminals with

wire, metal clips, solder or similar. (This applies

also to thermal fuses.)
(4) Removing air filters (except for replacement).
(5) Disabling relay functions (such as wedging pa-

per between relay contacts, etc.).
(6) Disabling safety functions (interlocks, safety cir-

cuits, etc.). Safety will not be assured, leading to

a risk of fire and injury.
(7) Performing actions to equipment not described

in the instruction manual or the service hand-

book.
(8) Using parts other than specified by Konica

Minolta.

[2] Checkpoints When Performing On-

site Service

Konica Minolta equipment is extensively tested before
shipping, to ensure that all applicable safety standards
are met, in order to protect the customer and customer
engineer from the risk of injury. However, in daily use, any
electrical equipment may be subject to parts wear and
eventual failure. In order to maintain safety and reliability,
the customer engineer must perform regular safety checks.

(3) Be sure to disconnect the power cord of the

equipment from the AC outlet.
Simply turning off the power switch is not suffi­cient, because paper feed units or other electri­cal equipment may be powered also when the
power switch is turned off.

(4) Proceed with special care when performing op-

eration checks or adjustment while the unit is
powered. When carrying out operation checks or
adjustment while external covers are removed,
the risk of electrical shock exists when touching
parts which carry high voltage or electrical charge.
The risk of injury exists when touching moving
parts such as gears or chains.

2. Safety Checkpoints

The following list is not exhaustive, but it includes actions
which must be carried out at every on-site service.

CAUTION:

(1) Check external covers and the frame for sharp

edges, burrs, or nicks.

(2) Check external covers and hinges for loosening

or damage.
(3) Check wiring for squeezing or damage.
(4) Check power cord for insulation problems (con-

ductor must not be exposed).
(5) Check power cord and cable ties etc. for loosen-

ing from frame.

WARNING:

(1) Verify that the equipment is properly grounded. If

a problem is detected, establish a proper ground

connection.
(2) Connecting the ground lead to an improper point

such as listed below results in a risk of explosion

and electric shock.

Unsuitable ground points:

- Gas pipe

- Lightning rod

- Telephone line ground

- Plastic water pipe or water pipe or faucet that
has not been approved by authorities for
grounding use

1. Advance Preparation for Safety Checks

CAUTION:

(1) Wear clothing that facilitates work and is de-

signed for safety.

(2) Carry out all procedures carefully to prevent in-

jury.

3. Description of Safety Checks

CAUTION:

(1) Before performing safety check work, read all

relevant documentation (service handbook, tech­nical notices, etc.) and proceed according to the
prescribed procedure, using only the prescribed
tools. Do not carry out any adjustments not
described in the documentation.

(2) If the power cord is damaged, replace it only with

the specified power cord. If the power cord insu­lation has been damaged and there are exposed
sections, short- circuits and overheating may
occur, leading to a serious fire risk.

(3) Do not route the power cord so that it can be

stepped on or pinched. Otherwise overheating
may occur, leading to a serious fire risk.

(4) When disconnecting any cables, always grasp

the connector and not the cable (especially in the
case of AC and high-voltage leads).

(5) Carefully remove all toner remnants from electri-

cal parts, electrodes, etc.

(6) Make sure that wiring cannot come into contact

with sharp edges, burrs, or other pointed parts.

(7) Double-check to make sure that all screws, com-

ponents, wiring, connectors, etc. that were re­moved for safety check maintenance have been
reinstalled in the original location. (Pay special
attention to forgotten connectors, pinched cables,
forgotten screws, etc.)

(8) When installation and preventive maintenance,

verify that the power cord has been securely
plugged into the AC outlet. Contact problems
may lead to increased resistance, overheating,
and the risk of fire.

WARNING:

Before disassembling or adjusting the equip­ment, make sure that the power cord has been
disconnected.

[4] Measures to Take in Case of an

Accident

(1) If an accident has occurred, the distributor who has

been notified first must immediately take emergency
measures to provide relief to affected persons and to
prevent further damage.

(2) If a report of a serious accident has been received

from a customer, an on-site evaluation must be
carried out quickly and Konica Minolta must be
notified.

(3) To determine the cause of the accident, conditions

and materials must be recorded through direct on­site checks, in accordance with instructions issued
by Konica Minolta.

(4) For reports and measures concerning accidents,

consult your superior, and follow the regulations set
in "Standards for the Control Program for Measures
Against Electrical Equipment Accidents".

[5] Conclusion

(1) Safety of users and customer engineers depends

highly on accurate maintenance and administration.
Therefore, safety can be maintained by the appropri­ate by the proper daily service work conducted by the
customer engineer.

(2) When performing service, equipment on the site

must be tested for safety. The customer engineer
must verify the safety of parts and ensure appropri­ate management of the equipment.

[3]

Handling of Materials for Servicing

CAUTION: Alcohol-based and acetone- based

cleaners are highly flammable and
must be handled with care. When
using these materials for cleaning
parts, observe the following precau-

tions.
(1) Disconnect the power cord from the AC outlet.
(2) Use only a small amount of cleaner at a time and

take care not to spill any liquid. If this happens,
immediately wipe it off.

(3) Perform cleaning only in an environment where

sufficient ventilation is assured. Breathing large
quantities of organic solvents can lead to dis­comfort.

(4) Do not replace the cover or turn the unit on before

any solvent remnants on the cleaned parts have
fully evaporated.

a. Interlock

FNS paper-conveyance drive control is initiated
by the ON signal from the main body START
button. If MS1 (interlock) is OFF at this time, how­ever, the finisher transmits an error signal to the
main body CB and does not begin control.

b. PS207 (paper exit cover open/close detection)

As mentioned above, FNS paper-conveyance
drive control is initiated by the ON signal from
the main body START button. But if PS207 (pa­per exit cover open/close detector) is [H] at this
time (paper exit cover is open), the FNS trans­mits an error signal to the main body CB and
does not begin control.

c. M1 (FNS conveyance) control

(1) Main tray paper exit operation

M1 is set ON by the ON signal of the START
button and goes OFF a preset time interval after
PS4 (FIN entrance passage) detects the trailing
edge of the final copy paper.

(2) Sub-tray paper exit operation

SD6 (sub-tray deceleration) turns ON a pre­defined time after PS4 detects the trailing edge of
the paper, and the deceleration roller is stuck with
pressure to the sub-tray exit roller (C). Thus the
speed of ejecting paper is reduced.
SD6 then turns OFF a predefined time after PS1
(sub-tray paper exit) detects the trailing edge of
the paper.

a. Conveyance to the stacker (sizes other than

A4 or B5)

(1) M13 (stacker entrance) ON timing

M13 is turned ON by the START button ON
signal, and begins with high speed rotation. M13
then switches to low speed rotation a preset time
period after PS5 (stacker conveyance passage)
detects the trailing edge of the paper.
M13 then returns to high speed rotation a preset
period after PS5 detects the trailing edge of the
paper. This action is repeated as necessary to
transport all papers to be stacked into the stacker.

(2) M13 OFF timing

M13 goes OFF a preset time period after PS5
detects the trailing edge of the final paper set.

b. Conveyance to the stacker (A4 and B5 sizes)

(1) First set

Paper for the first set to be stapled is conveyed in
the same way as other paper sizes.

(2) First paper of second and subsequent sets

M13 turns OFF a preset time period after PS4
(FNS entrance passage) detects the trailing edge
of the first paper for the second or subsequent
set, and the paper moves into the by-pass. This
prevents paper from moving into the stacker
while stapling of the previous set is still in progress.

(3) Second and subsequent papers of second and

subsequent sets
M13 resumes low speed rotation a preset time
period after PS4 detects the trailing edge of the
second paper of the set. This causes the first and
second papers to move together (one atop the
other) into the stacker. M13 switches to rapid
rotation a preset time period after PS5 detects the
trailing edge of the first and second papers, so
that it is ready to handle the third paper of the set
when it arrives from the main body. Third and
subsequent papers for the set are then conveyed
in the same way as the papers in the first set.

c. Paper alignment (trailing-edge alignment)

For operation in staple mode:
The swivel roller adjusts the position of each
paper (one paper at a time) within the stacker.
For operation in booklet mode (FS-211 only): The
stapling & folding stopper is moved and set into
appropriate position. The swivel roller adjusts the
position of each paper (one paper at a time).

MAIN BODY

When running in Sort or Group mode, the FNS carries
out shifting of paper. Shifting is driven by M2 (roller
shift), which is controlled by the FNS CB (FNS control
board).

1. Operation

If operation is in sort or group mode, M2 (roller
shift) turns ON a predetermined time period af­ter PS4 (FNS entrance passage) detects the trail­ing edge of a paper that needs to be shifted.
Rotation of M2 starts shifting of the conveyance
slide shaft, while rotation of M1 (FNS convey­ance) causes the shaft to turn, so that shifting
and conveyance occur simultaneously.
PS18 (roller-shift HP) turns ON when the con­veyance slide shaft has been fully shifted, caus­ing M2 to turn OFF.
A specified time period after PS4 turns OFF, M2
turns ON and returns the conveyance slide shaft
to its original position. PS18 turns OFF when the
conveyance slide shaft has returned all the way,
causing M2 to turn OFF again.
This operation is repeated as necessary to shift
paper as it moves toward the exit roller.

SD4 (paper exit opening) controls engagement by the
nip paper exit roller. SD4 is controlled by the FNS CB
(FNS control board).

1. Operation

When ejection is not in progress, a gap is main­tained between the nip paper exit roller and the
paper exit roller so as to prevent paper jams at
the paper exit.
At time of ejection, however, SD4 turns ON, in­clining the nip paper exit roller against the paper
exit roller so that the gap is closed.

MAIN BODY

M8 (paper exit opening) opens and closes the paper
exit by means of a linkage mechanism. M8 is controlled
by the FNS CB (FNS control board).

1. Operation

If large paper (the length in the paper feed
direction is 217 mm or more) is being stapled,
M8 turns ON when the START button ON signal
is received, causing the paper exit to open.
Upon completion of stapling, the stapling-com­pleted signal from the FNS CB causes the paper
exit to close, and the stapled set is exited.
The status of the paper exit opening is detected
by PS12 (paper exit opening).

*3 Stapling Operation

a. FS-111

The stapler motor/F (M24) and stapler motor/R
(M22) in the stapler (F and R) run to inject a staple
in order to bend it into the shape of the clincher.
Rotation control of the motors M24 and M22 are
exerted by the stapler HP PS/F (PS34) and sta­pler HP PS/R (PS31).
The cartridge detection PS/F (PS36) and car­tridge PS/R (PS39) detect presence and im­proper loading of a cartridge.
Staple detection PS/F (PS37) and staple detec­tion PS/R (PS40) detect presence of staples in
the cartridge.
After staples are charged, M24 and M22 run un­til the stapler ready PS/F (PS38) and stapler
ready PS/R (PS41) are turned ON by staples,
thus preventing blank stapling.

Each stapler houses a stapler motor, and each
clincher houses a clincher motor. Motors the
stapler motor/F(M24) and the stapler motor/R
(M22) eject the staples, while motors the clincher
motor/F (M23) and the clincher motor/R (M21)
bend the staples.
The timing for staple clinching is controlled by
stapler-internal sensors the clincher-timing PS/
R (PS32) and the clincher-timing PS/F (PS35).
Switching ON of PS32 and PS35 causes motors
M21 and the within the clinchers motor (M23) to
operate, initiating the clinch action.

FS-111

M11 (stapler movement) and M4 (stapler rotation)
move staplers (FS-111) or the staplers and clinchers
(FS-211) into position in accordance with the selected
stapling mode. Once in position, the stapler(s) execute
stapling. A stapling cycle is detected by ON-OFF-ON
activation of the various stapler and clincher home­position sensors; specifically: PS31 (stapler HP/R),
PS34 (stapler HP/F), PS30 (clincher HP/R), and PS33
(clincher HP/F). Operation is controlled by the FNS
CB (FNS control board) via the RB (relay board)(FS-

211) or directly (FS-111).

1. Operation

a. Single-staple movement control (front)

M11 turns ON when the main body issues the
START button ON signal, moves the staplers
(FS-111) or the staplers and clinchers (FS-211)
to the predetermined positions, and then stops.
When single-staple mode is completed, M11
moves the staplers (FS-111) or the staplers and
clinchers back to the ON position of PS11 (sta­pler movement HP) and then stops.

2 - 26

FS-111/FS-211

b. Single staple movement control (rear)

M11 (stapler movement) and M4 (staple rotation)
turn ON when the main body issues the START
button ON signal, move the staplers (FS-111) or
the staplers and clinchers (FS-211) to the pre­determined positions, and then stop. When sin­gle-staple mode is completed, M11 and M4 move
the stapler or the staplers and clinchers back to
the PS11 (stapler movement HP) and PS14 (sta­pler rotation HP) ON positions, and then stop.

c. Two staplers movement control

M11 and M4 come ON when the main body is­sues the START button ON signal, move the sta­plers (FS-111) or the staplers and clinchers (FS-

211) to the predetermined positions, and then
stops. When two-staple mode is completed, M11
and M4 moves the staplers and clinchers (FS-

211) back to the ON position of PS11 (stapler
movement HP) and then stops.

d. Control of the stapling-and-folding stopper

(stapling & folding) (FS-211 only)

On receipt of the START button ON signal, the
stapling-and-folding stopper is moved and set into
position. M14 (stapling-and-folding stopper)
moves the stopper into position, and M17 (sta­pling-and-folding stopper release) sets it. When
stapling action is completed, M17 releases the
stopper and the papers move to the folding unit.
Setting and releasing of the stopper is repeated
for each paper set.
When PS25 (folding paper exit) detects exiting
of the final paper set, M14 returns the stopper to
its home position. Arrival at home position is de­tected by PS23 (stapling-and-folding stopper HP).

e. Control of the stapler paper-end stopper

(folding) (FS-211 only)

On receipt of the START button ON signal, the
stapling-and-folding stopper is moved and set
into position. M14 moves the stopper into posi­tion, and M17 sets it.
A preset period after PS5 (stacker conveyance
passage) detects the final paper set, M17 re­leases the stopper and the papers move to the
folding unit. Setting and releasing of the stopper
is repeated for each paper set.
A preset period after PS25 detects the passage
of the final paper set, M14 returns the stopper to
its home position. Arrival at home position is de­tected by P23 (stapling-and-folding stopper HP).

f. Stapling action control

Upon closing of the alignment plate/upper (FS-

111) or the alignment plates/upper and lower (if
booklet mode)(FS-211), M22 (stapler/R) and M24
(stapler/F) turn ON, causing the staple-eject
plates to begin stapling. As the stapling opera­tion progresses, stapler-internal sensors PS32
(clincher timing/R) and PS35 (clincher timing/F)
come ON, causing clincher-internal motors M21
(clincher/R) and M23 (clincher/F) to come ON,
thereby initiating the clinching action (FS-211).
Stapling action is completed when the following
HP sensors have turned ON, detecting home po­sitions: PS31(stapler HP/R) and PS34 (stapler
HP/F)(FS-111) or PS31 , PS34 , PS30 (clincher
HP/R), and PS33 (clincher HP/F)(FS-211).
A staple-jam condition is detected if PS31 and
PS34 (FS-111) or PS31, PS34, PS30, and PS33
(FS-211) fails to come back ON within a preset
time period after going OFF. M22 and M24 (FS-

111) or M22, M24, M21, and M23 (FS-211) turn
in reverse until the corresponding components
have returned to home position (until PS31 and
PS34 (FS-111) or PS31, PS34, PS30, and PS33
(FS-211) come ON).
Control of these operations is implemented by
the FNS CB (FNS control board) via the RB (re­lay board) for FS-211 or directly by the FNS CB
for FS-111.

g. Cartridge detection

PS36 and PS39 (cartrige detection/F, /R) or SW1
(cartridge detection/R) and SW3 (cartridge de­tection/F)(FS-211) in the stapler detect the pres­ence or improper load of the respective cartridge.
The error message is displayed if the cartridge
is missing or is improperly set.

h. Staple-low detection

(1) FS-111

The PS37 (staple detection/F) and PS40 (staple
detection/R) detect presence of staples in the
cartridge. After staples are charged, the M24 and
M22 run until the PS38 (stapler ready/F) and
PS41 (stapler ready/R) are turned ON by staples,
thus preventing blank stapling.

(2) FS-211

When only few staples remain in the cartridge,
the SW2 (staple detection/R) and SW4 (staple
detection/F) turn ON to display an error message.

The counting program, built in the FNS, counts
the number of delivered sheets on the main tray
during continuous copying. When the total
number of delivered sheets reaches a maximum
(values are predefined depending on type/size
of paper), the copying operation is suspended.
However, when some delivered sheets are re­moved, the main tray is raised and the counter
reset PS is activated. This resets the current
sheets counter. This enables limitless delivery.
The tray lower limit PS (PS3) detects the bottom
of the main tray. The number of delivered sheets
on the main tray is not counted by the software
counter during non-continuous copying. PS3 is
used for the limitation of the number.

*1 Raising and lower (Main tray up-down)

The rotation of the tray up-down motor (M3) turns
the worm gear on the motor’s shaft. The rota­tional force propagates through the gear box and
turns the up-down shaft, thereby turning the pul­leys fixed to the ends of the shaft (one pulley at
each end). The wires attached to the pulleys
cause the tray to move up and down.
Clockwise turning of the M3 worm gear gener­ates upward tray movement, while
counterclockwise turning generates downward
movement.

*2 Paper detection

The distance between the top surface of the piled
sheets on the main tray (the top surface of the
main tray if there's no sheet on the tray) and the
paper exit opening is monitored using the tray
upper limit PS (PS2) and the stapler paper exit
upper limit PS (PS7). This distance is kept con­stant to avoid misalignment of delivered sheets.

The folding stopper motor (M18) moves the folding stopper into the predetermined position. The folding
conveyance motor (M20) drives the folding conveyance rollers and conveyance belt so as to transport the
paper up to this stopper.
The folding knife motor (M19) drives the folding knife. Paper is folded over by the action of the knife and
folding rollers, and the fold is pressurized by the action of the folding rollers and the pressure rollers. M20
drives the folding rollers and pressure rollers so as to eject the folded paper set into the booklet tray.

M18 (folding stopper) drives the folding stopper in
accordance with the paper size. M20 (folding
conveyance) transports the paper into position for
folding. Folding is implemented by the action of the
folding knife and the folding rollers.
The folding rollers and pressure rollers apply pressure
to the folded paper set while at the same time exiting
it to the booklet tray.
The folding knife is driven by M19 (folding knife).

1. Operation

On receipt of the START button ON signal from
the main body, M18 moves the folding stopper
into the predetermined position.
Upon completion of paper stapling, M20 starts
up and drives the folding conveyance rollers and
folding conveyance belt so as to transport the
stapled paper set up to the stopper.

Switching ON of PS28 (folding passage/1)
causes M20 to stop and M19 to start. The paper
is folded by the folding knife and folding rollers A
and B.
Upon completion of folding, M20 starts again,
driving folding rollers and pressure rollers so as
to exit the folded set into the booklet tray.
When PS25 (folding paper exit) detects exiting
of the paper set, M20 stops and M18 moves the
folding stopper to its home position, stopping
when PS27 (folding stopper HP) comes ON.
Control of these operations is implemented by
the FNS CB (FNS control board).
