SAFETY AND IMPORTANT WARNING ITEMS

Read carefully the Safety and Important Warning Items described below to understand them before doing service work.

IMPORTANT NOTICE

Because of possible hazards to an inexperienced person servicing this copier as well as the risk of damage to the copier, Konica Corporation strongly recommends that all servicing be performed only by Konica-trained service technicians. Changes may have been made to this copier to improve its performance after this Service Handbook was printed. Accordingly, Konica Corporation does not warrant, either explicitly or implicitly, that the information contained in this Service Handbook is complete and accurate. The user of this Service Handbook must assume all risks of personal injury and/or damage to the copier while servicing the copier for which this Service Handbook is intended. Therefore, this Service Handbook must be carefully read before doing service work both in the course of technical training and even after that, for performing maintenance and control of the copier properly. Keep this Service Handbook also for future service. When it is impossible to read the description about safety and warning (due to contamination or tear), the relevant page should be replaced.

DESCRIPTION ITEMS FOR DANGER, WARNING AND CAUTION

In this Service Handbook, each of three expressions, “ DANGER,” “ WARNING,” and “ CAUTION” is defined as follows together with a symbol mark to be used in a limited meaning. When servicing the copier, the relevant works (disassembling, reassembling, adjustment, repair, maintenance, etc.) need to be conducted with utmost care.

DANGER : Actions having a high possibility of suffering death or serious injury

WARNING : Actions having a possibility of suffering death or serious injury

CAUTION : Actions having a possibility of suffering a slight wound, medium trouble, and

property damage

Symbols used for safety and important warning items are defined as follows:

: Precaution when using the copier.

General precaution Electric hazard High temperature

: Prohibition when using the copier.

: Direction when using the copier.

SAFETY WARNINGS

[1] MODIFICATIONS NOT AUTHORIZED BY KONICA

Konica copiers are renowned for their high reliability. This reliability is achieved through high-quality design and a solid

service network.

Copier design is a highly complicated and delicate process where numerous mechanical, physical, and electrical aspects have

to be taken into consideration, with the aim of arriving at proper tolerances and safety factors. For this reason, unauthorized

modifications involve a high risk of degradation in performance and safety. Such modifications are therefore strictly

prohibited. the points listed below are not exhaustive, but they illustrate the reasoning behind this policy.

DANGER : PROHIBITED ACTIONS

• Using any cables or power cord not specified by Konica.

• Using any fuse or thermostat not specified by Konica. Safety will not be

assured, leading to a risk of fire and injury.

• Disabling fuse functions or bridging fuse terminals with wire, metal clips, solder or similar object.

• Disabling relay functions (such as wedging paper between relay contacts)

• Disabling safety functions (interlocks, safety circuits, etc.) Safety will not

be assured, leading to a risk of fire and injury.

• Making any modification to the copier unless instructed by Konica

• Using parts not specified by Konica

SAFETY AND IMPORTANT WARNING ITEMS

[2] CHECKPOINTS WHEN PERFORMING ON-SITE SERVICE

Konica copiers are extensively tested before shipping, to ensure that all applicable safety standards are met, in order to protect

the customer and customer engineer (hereafter called the CE) 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 CE must perform

regular safety checks.

1. Power Supply

WARNING: Wall Outlet

• Check that mains voltage is as specified. Plug the power cord into the dedicated wall outlet with a capacity greater than the maximum power consumption.

If excessive current flows in the wall outlet, fire may result.

• If two or more power cords can be plugged into the wall outlet, the total load must not exceed the rating of the wall outlet.

If excessive current flows in the wall outlet, fire may result.

WARNING: Power Plug and Cord

• Make sure the power cord is plugged in the wall outlet securely.

Contact problems may lead to increased resistance, overheating, and the risk of fire.

• Check whether the power cord is damaged. Check whether the sheath is damaged.

If the power plug, cord, or sheath is damaged, replace with a new power cord (with plugs on both ends) specified by Konica. Using the damaged power cord may result in fire or electric shock.

• When using the power cord (inlet type) that came with this copier, be sure to observe the following precautions: a. Make sure the copier-side power plug is securely inserted in the socket

on the rear panel of the copier. Secure the cord with a fixture properly.

b. If the power cord or sheath is damaged, replace with a new power cord

(with plugs on both ends) specified by Konica. If the power cord (inlet type) is not connected to the copier securely, a contact problem may lead to increased resistance, overheating, and risk of fire.

• Check whether the power cord is not stepped on or pinched by a table and so on.

Overheating may occur there, leading to a risk of fire.

SAFETY AND IMPORTANT WARNING ITEMS

WARNING: Power Plug and Cord

• Do not bundle or tie the power cord. Overheating may occur there, leading to a risk of fire.

• Check whether dust is collected around the power plug and wall outlet. Using the power plug and wall outlet without removing dust may result in fire.

• Do not insert the power plug into the wall outlet with a wet hand. The risk of electric shock exists.

• When unplugging the power cord, grasp the plug, not the cable. The cable may be broken, leading to a risk of fire and electric shock.

WARNING: Wiring

• Never use multi-plug adapters to plug multiple power cords in the same

outlet.

If used, the risk of fire exists.

• When an extension cord is required, use a specified one. Current that can flow in the extension cord is limited, so using a too long extension cord may result in fire. Do not use an extension cable reel with the cable taken up. Fire may result.

WARNING: Ground Lead

• Check whether the copier is grounded properly. If current leakage occurs in an ungrounded copier, you may suffer electric shock while operating the copier. Connect the ground lead to one of the following points: a. Ground terminal of wall outlet b. Ground terminal for which Class D work has been done

SAFETY AND IMPORTANT WARNING ITEMS

WARNING: Ground Lead

• Pay attention to the point to which the ground lead is connected. Connecting the ground lead to an improper point such as the points listed below results in a risk of explosion and electric shock: a. Gas pipe (A risk of explosion or fire exists.) b. Lightning rod (A risk of electric shock or fire exists.) c. Telephone line ground (A risk of electric shock or fire exists in the

case of lightning.)

d. Water pipe or faucet (It may include a plastic portion.)

2.Installation Requirements

WARNING: Prohibited Installation Place

• Do not place the copier near flammable materials such as curtains or

volatile materials that may catch fire.

A risk of fire exists.

• Do not place the copier in a place exposed to water such as rain water. A risk of fire and electric shock exists.

WARNING: Nonoperational Handling

• When the copier is not used over an extended period of time (holidays,

etc.), switch it off and unplug the power cord.

Dust collected around the power plug and outlet may cause fire.

CAUTION: Temperature and Humidity

• Do not place the copier in a place exposed to direct sunlight or near a heat

source such as a heater.

A risk of degradation in copier performance or deformation exists. Do not place the copier in a place exposed to cool wind. Recommended temperature and humidity are as follows: Temperature: 10°C to 30°C Humidity: 10% to 80% (no dew condensation) Avoid other environments as much as possible.

CAUTION: Ventilation

• Do not place the copier in a place where there is much dust, cigarette

smoke, or ammonia gas.

Place the copier in a well ventilated place to prevent machine problems and image faults.
