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 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 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: |
L (line) |
• White or Light Blue: |
N (neutral) |
|
• |
Green/Yellow: |
PE (earth) |
Wrong connection may cancel safeguards within the product, and results in fire or electric shock.

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 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. |
? V |
•Connect power plug directly into wall outlet having same configuration as the plug.
Use of an adapter leads to the product connecting to |
kw |
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.

SAFETY AND IMPORTANT WARNING ITEMS
Connection to Power Supply
WARNING
• 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.
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 or cord set (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.

SAFETY AND IMPORTANT WARNING ITEMS
Power Plug and Cord
WARNING
•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.
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.

D. Paper feed direction
When the direction in which paper is fed is in parallel with the longer side of paper, the paper feed direction like this is referred to as the longitudinal feed.
And the paper feed direction that is perpendicular to the longitudinal feed is referred to as the transverse feed.
When specifying the longitudinal feed, "S (abbreviation for Short Edge Feeding)" is added to the paper size. For the transverse feed, no specific notation is employed.
However, when only the longitudinal feed is specified for one and the same paper size with no specification made for the transverse feed, "S" is not added even when being fed longitudinally.
