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!

Mechanism
1. Paper conveyance
Paper conveyance is performed by the conveyance rollers A, B, C and D, the intermediate roller, conveyance slide shaft and subtray paper exit roller. These components are driven by the 1st conveyance motor (M1) and the 2nd conveyance motor (M4) through the timing belt.
Stacking to the paper stacker is performed by the stacker entrance roller and sponge roller. These are driven by the stacker entrance motor (M14) via the timing belt.
Paper exiting is performed by the stacker paper exit belt arm and the paper exit rollers. These are driven by the paper exit motor (M7) via the timing belt.

(3)Pressure of the paper exit roller
The paper exit roller rotation is slower than the conveyance rollers A, B and C. Therefore pressure is released at times other than when paper is exiting.
When the paper reaches the paper exit opening the paper exit roller applies pressure and paper is exited to the main tray. Thepressing and releasing of paper is performed by the paper exit opening solenoid (SD4).

6.Intermediate conveyance roller
In this machine, in order to be compatible with thick paper, it has its pressure of the intermediate conveyance roller set at a slightly higher level.
While in conveyance collectively of the 1st and 2nd copies of the 2nd set and later to the stacker in staple copy mode for small-sized paper, the decompression solenoid (SD3) is operated to lower the pressure of the intermediate conveyance roller.
This is to prevent dirt from the roller from sticking to the paper and wrinkles from taking place on paper in conveyance.
