SAFETY WARNINGS
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 reason-
ing behind this policy .
DANGER: PROHIBITED ACTIONS
• 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

VICE
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 engi-
neer (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.

WARNING: Power Plug and Cord
• 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.
• When using the power cord (inlet type) that came with this
product, be sure to observe the following precautions:
a. Make sure the connector is securely inserted in the inlet
on the rear panel of the product.
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
KMBT.
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.
• 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.
