SAFETY AND IMPORTANT WARNING ITEMS
SAFETY WARNINGS
[1] MODIFICATIONS NOT AUTHORIZED BY KONICA MINOLTA BUSINESS TECHNOLOGIES, INC.
KONICA MINOLTA brand products are renowned for their high reliability. This reliability is achieved through high-quality design and a solid service network. Product 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 media 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 product unless instructed by KMBT · Using parts not specified by KMBT

SAFETY AND IMPORTANT WARNING ITEMS
[2] POWER PLUG SELECTION
In some countries or areas, the power plug provided with the product may not fit wall outlet used in the area. In that case, it is obligation of customer engineer (hereafter called the CE) to attach appropriate power plug or power cord set in order to connect the product to the supply.
Power Cord Set or Power Plug WARNING
· Use power supply cord set which meets the following criteria: - provided with a plug having configuration intended for the connection to wall outlet appropriate for the product's rated voltage and current, and - the plug has pin/terminal(s) for grounding, and - provided with three-conductor cable having enough current capacity, and - the cord set meets regulatory requirements for the area. Use of inadequate cord set leads to fire or electric shock. · Attach power plug which meets the following criteria: - having configuration intended for the connection to wall outlet appropriate for the product's rated voltage and current, and - the plug has pin/terminal(s) for grounding, and - meets regulatory requirements for the area. Use of inadequate cord set leads to the product connecting to inadequate power supply (voltage, current capacity, grounding), and may result in fire or electric shock. · Conductors in the power cable must be connected to terminals of the plug according to the following order: · Black or Brown: · White or Light Blue: · Green/Yellow: L (line) N (neutral) PE (earth)

SAFETY AND IMPORTANT WARNING ITEMS
[3] CHECKPOINTS WHEN PERFORMING ON-SITE SERVICE
KONICA MINOLTA brand products 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
Connection to Power Supply WARNING
· Check that mains voltage is as specified. Connection to wrong voltage supply may result in fire or electric shock. · 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. · 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. · 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 product is grounded properly. If current leakage occurs in an ungrounded product, you may suffer electric shock while operating the product. Connect power plug to grounded wall outlet.

SAFETY AND IMPORTANT WARNING ITEMS
Power Plug and Cord WARNING
· When using the power cord set (inlet type) that came with this product, make sure the connector is securely inserted in the inlet of the product. When securing measure is provided, secure the cord with the fixture properly. If the power cord (inlet type) is not connected to the product 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.
· 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 plug and connector on each end) specified 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.
· 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.
S-5
SAFETY AND IMPORTANT WARNING ITEMS
Wiring WARNING
· 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. 2. Installation Requirements
Prohibited Installation Places WARNING
· Do not place the product near flammable materials or volatile materials that may catch fire. A risk of fire exists. · Do not place the product in a place exposed to water such as rain. A risk of fire and electric shock exists.
When not Using the Product for a long time WARNING
· When the product 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.
S-6
SAFETY AND IMPORTANT WARNING ITEMS
Ventilation CAUTION
· The product generates ozone gas during operation, but it will not be harmful to the human body. If a bad smell of ozone is present in the following cases, ventilate the room. a. When the product is used in a poorly ventilated room b. When taking a lot of copies c. When using multiple products at the same time
Stability CAUTION
· Be sure to lock the caster stoppers. In the case of an earthquake and so on, the product may slide, leading to a injury.
Inspection before Servicing CAUTION
· Before conducting an inspection, read all relevant documentation (service manual, technical notices, etc.) and proceed with the inspection following the prescribed procedure, using only the prescribed tools. Do not make any adjustment not described in the documentation. If the prescribed procedure or tool is not used, the product may break and a risk of injury or fire exists. · Before conducting an inspection, be sure to disconnect the power plugs from the product and options. When the power plug is inserted in the wall outlet, some units are still powered even if the POWER switch is turned OFF. A risk of electric shock exists. · The area around the fixing unit is hot. You may get burnt.
S-7
SAFETY AND IMPORTANT WARNING ITEMS
Work Performed with the Product Powered On WARNING
· Take every care when making adjustments or performing an operation check with the product powered.
