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.

∙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

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 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

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

FS-107

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.

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.

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).

1.Operations

a. Tray lower limit detection operation

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.
