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.

(no holes are made). Either of
these modes can be selected on
the operation panel of the main
body.When both the punch mode
and the Z folding mode (Z fold­ing is on) are selected, the Z fold­ing process as well as the punch
process will be performed.
Refer to the "Z folding process"
section for more information on
the Z folding action.

The following flowchart shows the flow of
operations performed by the above sections.
These operations are explained hereunder
according to this flowchart.

[1] Number of punch holes switching (PZ-109 only)

When the punch mode is active, turning ON START BUTTON of the main body enables the punch switching
motor (M8) to switch the number of punch holes.
When M8 is activated, the punch switching cam is rotated clockwise and the eccentric cams are shifted
forward and backward via the eccentric cam cover. When the eccentric cams are shifted forward, the
eccentric cams for 3 holes (4 holes for Metric area) are set in the eccentric cam bearings, the eccentric cams
for 2 holes come off the bearings. When the eccentric cams are shifted backward, these settings are
switched in reverse way. (For Metric area specification, since 2 holes in central position are also used as
part of 4 holes, the 2 holes are always set in the eccentric cam bearings.)
When the non-punch mode is active and when the number of punches are the same as in previous copying
time, this operation is not performed.

[2] Switching Mechanism of Gate/L

When the z-folding mode is on, all paper sheets
are conveyed to the upper conveyance path
section.

When the z-folding mode is off, the paper
conveyance path is switched between the upper
conveyance path section or the exit conveyance
roller section, depending on the size of paper and
the current setting of the punching process. This
switching action is performed by the gate/L, which
is driven by the gate SD/L (SD1). In the idling
mode, the gate/L is set toward the exit
conveyance roller (straight exit) section (SD1 is
off).

1. The punch mode is on:

When the punch mode is active, small size paper
sheets are carried to the straight exit section, and
large size paper sheets are carried to the upper
conveyance path section. The large size sheet
that is conveyed to the upper conveyance path
will be controlled by the gate/U, and fed through
the conveyance drive roller and the 1st folding
roller to the exit conveyance rollers.

[3] Standby Position of Punch Unit

In the punch mode, the punch unit is moved by
the punch shift motor (M5) so that the paper edge
sensor corresponding to the paper size (the
rightmost sensor for the A4 paper printed in
landscape orientation) is positioned 5 mm inside
the paper edge. When the M5 rotates, its force
is transferred to the rack via the timing belt, thus
moving the punch unit.
In the non-punch mode, the above operation is
not performed.

Punch unit

[4] Formation of a Registration Loop

In the punch mode,the main motor (M1) turns
OFF temporarily to stop conveyance of paper
when the specified time has passed since the
paper edge sensor detected the leading edge of
the paper. Thus, the paper is pressed against
the registration roller forming a loop. When the
specified time passed, the M1 turns ON to restart
conveying the paper.
In the non-punch mode,the above operation is
not performed.

[5] Conveyance

When small-size paper is used in the punch mode
or the non-punch mode is selected, paper is ejected
straight to the FNS via the exit conveyance roller.
When large-size paper is used, the gate is at the
down position and therefore paper is ejected via
the upper conveyance roller and conveyance drive
roller. When the z-folding mode is also selected
by the operation panel of the main body, the gate/
L and gate/U are switched. Thus, paper is carried
to the z-folding section for the z-folding process
via the conveyance roller and conveyance drive
roller irrespective of its size. Refer to “Z-FOLDING
PROCESS” section for more information on the z­folding action.

[6] Adjustment of Punching Position

The punch unit that has been positioned 5 mm
inside the paper edge moves to the center of
paper in the procedure described below.
The punching position is adjusted by moving the
punch unit back and forth during conveyance of
paper.

• The punch unit moves backward until the
specified side edge sensor on paper edge
sensor detects the side edge of paper.

• Next, the punch unit moves forward until the
side edge sensor detects the side edge of
paper again. (Detection of reference position)

• The punch unit moves forward again to position
the punch edges at the center of paper.

Holes are punched when the specified time has
passed since the paper edge sensor detected
the trailing edge of the paper. The main motor
(M1) turns OFF to stop paper conveyance
temporarily.
During punching, the punch motor (M4) is rotating
clockwise when viewed from the rear side. When
the punch clutch (MC1) turns ON, the drive force
of the M4 is transferred to the shaft to rotate the
shaft once. As the shaft rotates, the eccentric
cams of the shaft rotate to lower the punch edges,
making holes in the paper. After punching, the
M1 turns ON to eject the paper.

Note: The action of the z-folding process is different depending on whether the current mode is the

z-folding or non z-folding mode. The current mode is selected on the operation panel of the
main body. When both the z-folding and punch (sheets are punched) modes are selected, the
z-folding and punch processes are performed at the same time. Refer to the "PUNCHING
PROCESS" section for more information on the punch action.

[1] Switching Mechanisms of Gate/L

and Gate/U

1. The z-folding mode is active:

When the z-folding mode is active, paper sheets
are controlled by the gate/U controls and carried
to the upper conveyance path section regardless
of the sizes. The sheet conveyed to the upper
conveyance path section then will be carried to
the z-folding section by the gate/L. The gate/L
and the gate/U are driven by the gate SD/L (SD1)
and the gate SD/U (SD2) respectively.

2. The non z-folding mode is active:

When the non z-folding mode is active, the paper
(large size paper for the punching process) is
conveyed to the upper conveyance path section.
Then it is controlled by the gate/U, and fed
through the conveyance drive roller and the 1st
folding roller to the exit conveyance rollers.

[2] Positioning of 1st and 2nd Folding Stoppers

Both the 1st and 2nd folding stoppers have its own paper stopper, determining at which position the paper is
folded. The PZ operation start request signal is sent from the main body to rotate the 1st stopper motor (M2)
and the 2nd stopper motor (M3), which returns the 1st and 2nd folding stoppers to their waiting/home
positions (HP). The paper stopper of the 2nd folding stopper is positioned at the bottom to ensure a normal
paper conveyance.
When the paper size signal is received from the main body, the 1st stopper motor (M2) is activated to drive
the 1st folding stopper. This positions the paper stopper of the 1st folding stopper at a point matching the
current paper size. The 1st and 2nd folding stoppers return to their home positions when the FNS operation
end signal is received.

[3] 1st Folding

The paper is fed by the registration roller, the conveyance roller, and the conveyance drive roller and carried
to the 1st folding stopper through the gate/U. When the front end of the paper touches the 1st folding
stopper, the upper middle portion of the paper is curled toward the conveyance drive roller and the 1st
folding roller. The front end of the curled paper is pulled into the contact point between these rollers, and the
paper is folded. The folded paper is carried to the 2nd folding stopper section. Because the 1st folding roller
is driven by the conveyance drive roller through the gear, the rotation speed of both rollers is the same.
The 1st folding roller is pressed against the conveyance drive roller and the 2nd folding roller by a spring,
ensuring firm contact conditions between the rollers.
When the punch mode (sheets are punched) is also enabled in the conveyance section of the main body,
the registration motor (M1) and the conveyance motor (M6) temporarily stop upon completion of the 1st
folding process to perform the punch action. Then the M1 and M6 restart to resume the z-folding process.
(Refer to the "Punching process" section for more information on the punch action.)

[4] 2nd Folding

The paper is conveyed to the 2nd folding section and the front edge of it bumps into the 2nd folding stopper,
coming to halt. This makes a loop in the paper in the space between the contact face of the 1st and 2nd
rollers and the contact face of the 1st folding roller and the conveyance drive roller. The front portion of the
loop is pulled into the contact surface between the 1st and 2nd rollers and folded.
During folding operation, when the front edge of the paper have passed through the passage PS (PS1), the
2nd stopper motor (M3) operates to move the 2nd folding stopper to the escape position near the waiting
position (HP). This action makes sure that the paper is fed normally.

The paper output from the main body is carried by the
M1 (registration) and the M6 (conveyance). Both the
M1 and M6 are stepping motors, driven by the PZCB
(PZ control board). The M6 is cooled down by the M10
(conveyance motor fan). Related signals are paper
edge sensor, SD1 (gate/L), SD2 (gate/U), PS9
(conveyance encoder), PS1 (passage), and PS8 (exit).

1. Operation

The M1 (registration) and the M6 (conveyance)
are turned ON by the PZ operation request sig­nal, and turned OFF when a predefined time has
elapsed since the paper was ejected.
The PS9 (conveyance encoder) detects the step
out condition of the M6 by monitoring the rota­tion of the encoder board attached to the shaft of
the M6.
The conveyance section consists of the regis­tration and conveyance sections.

a. Registration section

The M1 is temporarily stopped when a predefined
time has elapsed since the paper edge sensor
detected the leading edge of the paper conveyed
from the main body. A loop is formed in the pa­per, helping correct paper skew.
The registration control may not be performed in
the non-punch mode.

b. Conveyance section

(1) Punch mode (Large-size paper)

The SD1 (gate/L) is turned ON when the paper
edge sensor detects the leading edge of the
paper, and the paper is ejected through the upper
conveyance path. The PS1 (passage) and the
PS8 (exit) detect whether the paper is of large
size or not. The SD1 is turned OFF when a
predefined time has elapsed since the PS8 de­tected the paper.

(2) Punch mode (small-size paper) / Non-punch mode

Because the SD1 (gate/L) is in the OFF state, the
paper is ejected without any process.The PS8
(exit) detects the paper ejection.

(3) Z-folding mode

Regardless of paper size, the SD1 (gate/L) and
the SD2 (gate/U) are turned ON when the paper
edge sensor has detected the leading edge of the
paper. After the paper is conveyed through the
upper conveyance path, the 1st folding is per­formed in the 2nd stopper section, followed by the
2nd folding in the 2nd folding section and the
ejection. The PS1 (passage) and the PS8 (exit)
detect the paper. The SD1 and the SD2 are
turned OFF when a predefined time has elapsed
since the PS8 detected the paper.

1. Operation

a. 1st folding position setting

The position of the paper stopper on the 1st fold­ing stopper sets the paper position for 1st fold­ing.
The M2 (1st stopper) is activated by the PZ op­eration request signal to start searching for its
HP. When the PS3 (1st stopper HP) detects the
HP, the M2 stops. Then, upon receipt of the pa­per size signal from the main body, the M2 drives
the 1st folding stopper to the position where the
1st folding is performed for the paper of the speci­fied size.
When the PZ operation end signal is received
from main body, the M2 starts searching for its
HP to return the 1st folding stopper there.

The M3 (2nd stopper) sets the position of the paper
for the 2nd folding. Related signals are PS2 (2nd
stopper HP), PS1 (passage), and PS8 (exit).

1. Operation

a. 2nd folding position setting

The position of the paper stopper on the 2nd fold­ing stopper sets the paper position for 2nd fold­ing.
The M3 (2nd stopper) is activated by the PZ op­eration request signal to start searching for its
HP. When the PS2 (2nd stopper HP) detects the
HP, the M3 stops. Then, upon receipt of the pa­per size signal from the main body, the M3 drives
the 2nd folding stopper to the position where the
2nd folding is performed for the paper of the
specified size.
After the completion of the 2nd folding, the pa­per is carried forward. When the PS1 (passage)
detects the rear edge of the paper, the M3
counterrotates to drive the 2nd folding stopper in
the inverse direction, which makes the paper
stopper move to the escape position. With the
paper stopper at this position, the paper is fed
normally.
When the PS8 (exit) detects the end of the pa­per, the M3 is activated to move the paper stop­per to the original position for the next z-folding
action.
When the PZ operation end signal is received
from main body, the M2 starts searching for its
HP again to return the 2nd stopper there.
