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.

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.

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!

1. Operation

Each tray has a series of actuators that are operated by the paper guides. When each tray is inserted, these projections turn the tact switches on the PFUDB (PFU) OFF and ON. The PFUDB (PFU) determines the paper size of the PFU from the ON/ OFF combinations.

Up/down motor

Coupling gear

The paper tray (LCT) is suspended using four Up/ Down drive wires (A, B, C and D). When paper is loaded into the tray, the tray moves down due to the weight of the paper. The weight of the paper is balanced by the tension of the drive auxiliary spring. When the paper tray (LCT) is inserted, the up/down motor (M403) rotates, winding the wires on the drive reel and raising the tray. When the paper tray is withdrawn from the frame, the tray drive section and the coupling separate from each other. This causes the tray to move down to the position where the paper is balanced by the tension of the drive auxiliary spring.

SD402

Paper is fed by transmitting the M401 (paper feed) driving force to the paper feed roller and feed roller through SD402 (paper feed (LCT)). M401 is driven by the PFUDB (PFU drive board (PFU)) and controlled by the paper feed drive board PFUDB (PFU) in the main body. SD402 is driven by the PFUDB (PFU drive board (LCT)) and controlled by the PFUDB (PFU).

1. Operation

a. Initial operation when the power is switched ON

(1) When the power is switched ON, M401 goes ON for the

specified period.

Reason: This is to prevent the paper from being fed from

all of the paper trays at the same time when the Start button is pressed, as a result of the the ratchet claw of SD402 being disengaged due to an impact when the machine was being transported.

b. Operation when copying

Paper feed for the first sheet starts a specified time after the start button is turned ON. The paper feed operation starts when the M401 and SD402 turn ON. The M401 turns OFF a specified time after the PS401 (paper feed detect) detects the leading edge of the page. SD402 turns OFF a specified time after turning ON. Paper feed for the second and subsequent sheets starts specified time after the SD402 for the previous page turns ON.

When the paper tray is empty, PS404 (no paper detect (LCT)) changes to a high signal (L), to inform the PFUDB (PFU) in the main body that there is no paper in the tray.

DB-208/608

2. Signals

a. Input signals

(1) PS401 (PS401 to PFUDB (PFU))

This signal is output when PS401 (no paper detect) detects paper passing through the paper conveyance section. It changes to an [H] signal when paper is detected.

(2) PS404 (PS404 to PFUDB (LCT) to PFUDB (PFU))

This signal is a no-paper detecting signal for the LCT. [L]: When there is no paper in the tray

[H]: When there is paper in the tray

b. Output signals

The paper tray is raised when the M403 (up/down (LCT)) driving force is transmitted to the paper tray through the up/down drive wires (four for each tray). The M403 is driven by the PFUDB (LCT) (PFU detection board (LCT)) and controlled by the PFUDB (PFU) (PFU drive board (PFU)).

1. Operation

When the SW405 (LCT tray insertion detection) turns ON, the M403 turns ON and raises the tray. After the tray is raised, the PS405 (upper limit detect (LCT)) detects the upper limit of the paper in the tray. The M403 turns OFF and the tray stops. When paper is fed the PS405 turns OFF and the tray is raised when the M402 (up/down) turns ON again. The paper tray is lowered mechanically.

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. For ordering options, contact Konica’s Parts Distribution Center.

When ordering parts, be sure to specify part numbers exactly as listed in this catalog.

NOTE: Electrical parts may include previously used components.
