SAFETY AND IMPORTANT WARNING ITEMS

SAFETY WARNINGS
1. MODIFICATIONS NOT AUTHORIZED BY KONICA MINOLTA BUSINESS TECHNOLOGIES, INC.
Konica Minolta brand 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.

PROHIBITED ACTIONS DANGER
· Using any cables or power cord not specified by KMBT.

· Using any fuse or thermostat not specified by KMBT. 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 KMBT

· Using parts not specified by KMBT

SAFETY AND IMPORTANT WARNING ITEMS

CHECKPOINTS WHEN PERFORMING ON-SITE SERVICE

Konica Minolta brand 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. 2.1 Power Supply

Connection to Power Supply WARNING
· 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.

kw

· Connect power plug directly into wall outlet having same configuration as the plug. Use of an adapter leads to the product connecting to inadequate power supply (voltage, current capacity, grounding), and may result in fire or electric shock. If proper wall outlet is not available, advice the customer to contact qualified electrician for the installation.

· 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.

Ground Lead WARNING
· 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

Ground Lead WARNING
· 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.)

Power Plug and Cord WARNING
· For the products that use the power cord set (inlet type), be sure to follow the directions given below. When securing measure is provided, secure the cord with the fixture properly. a. Be sure to check to see if the power cord is securely inserted into the main body side inlet. b. When the fixing of the cord is indicated in the installation instructions, be sure to fix it securely by using the fixing materials provided in the same package. c. When the power cord is damaged with its sheath broken, be sure to replace it with the specified power cord set. When the power cord is not securely inserted, an abnormal heat may generates due to a poor contact of the cord, thus resulting in a 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. · 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) sp
ecified by KMBT. Using the damaged power cord may result in fire or electric shock.

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