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 oper-

ated 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 nor-

mal, 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 poten-

tial hazard might exist. For example, a laboratory

might use organic compounds which, when they

evaporate, make the room air volatile. Potentially dan-

gerous conditions might be seen or smelled. The

presence of substances such as cleaners, paint thin-

ners, gasoline, alcohol, solvents, explosives, or simi-

lar items should be cause for concern.

If conditions such as these exist, take appropriate

action, such as one of the following suggestions.

• 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 ma-

chine, and take appropriate action.

Unauthorized Modifications

Konica copiers have gained a reputation for being

reliable products. This has been attained by a combi-

nation 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 elec-

tronic aspects. It is not reasonable to expect individu-

als not involved in product engineering to know what

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-inclu-

sive, 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.

General Safety Guidelines

This copier has been examined in accordance with

the laws pertaining to various product safety regula-

tions prior to leaving the manufacturing facility to

protect the operators and service personnel from

injury. However, as with any operating device, compo-

nents 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 continu-

ing.

• Look for sharp edges, burrs, and damage on all

external covers and copier frame.

• Inspect all cover hinges for wear (loose or bro-

ken).

• Inspect cables for wear, frays, or pinched areas.

SAFETY PRECAUTIONS

• Ensure that the power cord insulation is not dam-

aged (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 alco-

hol, 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 apply-

ing power or installing covers.

Summary

It is the responsibility of every technician to use pro-

fessional 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 pre-

sent, 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!

*2: Paper Conveyance

When the paper has been switched to tray 2/3 by the

switching gate, the conveyance roller conveys it to

the conveyance drum until it enters the grip plate on

the circumference of the drum.

The grip plate closes due to the force of a cam and

spring arrangement and grasps the paper.

When the rotation speed of the drum increases, the

paper is pushed out and separated from the

conveyance drum. When the grip plate on the

conveyance drum reaches the paper exit position,

the paper hits a stopper and is separated from the

grip plate.

Behind the grip plate on the drum circumference,

there are two alignment plates. When these reach

the paper exit position, their own weight causes them

to open, and the rubber section at the plate tip aligns

the paper against the stopper.

The grip plate and alignment plates on the

conveyance drum do not use electrical control, they

operate only through the rotation of the drum. (The

grip plate is driven by the drum via a cam

arrangement, and the alignment plates are driven by

the centrifugal force and their own weight.)

The conveyance drum and conveyance rollers are

controlled electrically by conveyance drum motor

(M807) and conveyance motor (M801).

*3: Tray lift

The paper exit position for the paper sent to tray 2/3

is fixed. Switching between tray 2 and tray 3 is

carried out by changing the tray position with the tray

lift (up/down) mechanism.

The tray lift mechanism is driven by the tray up/down

motor (M804) whose driving force is transmitted to the

tray by a wire arrangement.

MAIN BODY

Paper exit conveyance takes place as a result of the

transmission of the drive force of motor M801

(conveyance) to the paper exit rollers and conveyance

rollers. The paper conveyance path is switched between

tray 1 or tray 2/3 by solenoid SD801 (gate).

M801 and SD801 are controlled by the FNSCB (FNS

control board).

1. Operation

a. Gate switching operation

Normally, SD801 is OFF and the gate allows paper to

exite to tray 2/3. When tray 1 is selected as the paper

exit tray, SD801 goes ON, the gate is switched, and

the paper is conveyed to tray 1.

b. Conveyance operation

M801 is turned ON and OFF in conjunction with the

copy operation of the main body. During operation of

the main body, the M801 rotates constantly, enabling

paper conveyance at any time.

When paper has been conveyed to tray 2/3, the

status of the PS802 (drum entrance) and main body

PS1 (paper exit) causes the M801 to be switched

from low speed to high speed. The high-speed

activation signal and the rotation speed depend on

the paper size.

MAIN BODY

The paper that has been sent to tray 2/3 is exited into the

respective tray by the conveyance drum. The conveyance

drum is driven by M807 (conveyance drum) which is

controlled by the FNSCB (FNS control board).

1. Operation

a. Conveyance operation

When PS802 (drum entrance) detects the leading

edge of the paper and goes ON, M807 is turned ON

after the specified time, and the conveyance drum

starts to rotate.

To convey one sheet of paper, the M807 is switched

through a predetermined sequence of three speeds.

When the conveyance drum reaches the standby

position, the motor is switched OFF.

During this time, the drum makes one revolution

which includes gripping, conveying, and releasing

the paper.

b. M807 speed control

When the conveyance drum rotation pulses reach a

predetermined number, the rotation speed is

changed.

The paper exit position of the conveyance drum is always

fixed, and tray switching is carried out by raising or

lowering tray 2/3.

The up/down motion is achieved by transmitting the

driving force of motor M804 (tray up/down) to the lift wires

connected to each tray. This operation is controlled by the

FNSCB (FNS control board).

1. Operation

Normally, the paper exit position of the conveyance

drum is aligned with tray 2. Therefore no lift operation

is carried out when tray 2 is selected.

a. Upward movement

When tray 3 is selected as paper exit tray and PS806

(traylower limit) is ON, M804 (tray up/down) goes ON

(forward rotation). Tray 2 and tray 3 are then raised

simultaneously.

When the upward movement causes tray 2 to switch

PS805 (tray upper limit) to ON, M804 goes OFF and

the upward movement stops. Tray 3 is now aligned

with the paper exit position of the conveyance drum.

b. Downward movement

When tray 2 is selected as paper exit tray and PS805

is ON, M804 goes ON (reverse rotation). Tray 2 and

tray 3 are then lowered simultaneously.

When the downward movement causes tray 3 to

switch PS806 to ON, M804 goes OFF and the

upward movement stops. Tray 2 is now aligned with

the paper exit position of the conveyance drum.

c. Tray squeeze prevention

During tray upward or downward movement, if a

foreign object is caught between the tray and the

finisher unit, MS802 (up/down (upper)) or MS803

(up/down (lower)) will mechanically go OFF, causing

the power supply line of M804 to be cut off.

*2: Paper exit

The paper being supplied by the conveyance drum is

conveyed to the stapling position, regardless of

whether stapling will be carried out or not. If stapling

is enabled, the stapled stack is exited to tray 2 or 3

after stapling. If stapling is not enabled, each sheet is

exited individually to tray 2 or 3.

This movement is performed by the exit levers which

are driven by the paper exit motor (M805).

*3: Paper stacking

A spring arrangement in the bottom of tray 2 and tray

3 lifts the bottom plate up, so that it always is in direct

contact or not more than 3 mm away from the paper

exit roller assembly.

[ Operation in through mode ]

The paper is stacked on the tray by the movement of

the exit lever and the rotation of the paper exit roller

(A) of each tray.

When the paper exit roller (A) turns, the tip of the

paper is grasped by the rollers and is stacked under

the rollers.

[ Operation in offset mode ]

The paper is offset by the alignment plates (front/

rear), and is stacked on the tray by the movement of

the exit lever and the rotation of the paper exit roller

(A) of each tray.

By repeating this action, the tip of the paper is

grasped by the rollers and is stacked under the

rollers.

*4: Staple accident prevention

A shutter cover is provided to prevent the user from

inadvertently inserting a finger etc. into the stapler. The

shutter cover is driven by the shutter SD (SD802) which

is ON during stapler operation and during stapler unit

movement. The shutter cover blocks the clearance

between the paper exit tray and the stapler unit.

MAIN BODY

The paper exited by the conveyance drum is aligned on

the center of the respective exit tray by the alignment

plates driven by the M808 (alignment (rear)) and M809

(alignment (front)). M808 and M809 are controlled by the

FNSCB (FNS control board).

1. Operation

a. Non-shift alignment operation

The alignment plate (front) and alignment plate (rear)

work symmetrically, with the tray center serving as

the reference point. The guides repeat the alignment

and release pattern. The rotation direction of M809

and M808 is therefore always opposite.

The ON timing of M809 and M808 is referenced to

the ON/OFF state of PS802 (drum entrance) or

PS804 (paper through detect). Which sensor is used

depends on the paper size.

b. Shift alignment operation

During the first alignment operation, the alignment

plate (front) and alignment plate (rear) are front and

rear symmetric with respect to operation as

reference with the center of the tray and paper is

exited.

During the next alignment operation, the alignment

plate (front) and alignment plate (rear) are not front

and rear symmetric with respect to operation as

reference with the center of the tray and paper is

exited at the position shift to the first copy.

From now on, these operation are repeated.

The ON/OFF timing of M809 and M808 is the same

as that of the non-shift alignment operation.

c. Staple mode operation

In staple mode, M809 and M808 perform release

operation after stapling is completed. The ON/OFF

timing is based on the OFF timing of the stapler motor

that last completed a stapling operation (M802 or M803).
