CMS REPLACEMENT INSTRUCTIONS

1. Drum unit/K, Ozone filter, Toner filter

Introduction

CMS:

• The CMS (Customer Maintenance Support) is a system that supports the customer who
conducts a parts replacement operation by himself without getting an technical assis­tance from the customer engineer, to minimize the downtime (shutdown period of the
machine operation) of the machine of the customer.

Notices to the customer who employs the CMS:

• When you want to employ the CMS, be sure to follow the instructions given by the cus-
tomer engineer.
And also, when you conduct a part replacement operation, be sure to read each replace­ment instruction and follow the specific instructions given in it. For your safety while in the
replacement operation, be sure to keep this CMS Instructions for Replacement safely,
and also be careful not to get it lost. Should it get lost, contact our service representative.

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 cur-
rent 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 prod
ing 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 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
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.

kw

•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 w
and wall outlet.

• Do not insert the power plug into the wall outlet with a wet
hand.

• When unplugging the power cord, grasp the plug, not the
cable.

hether dust is collected around the power plug

Using the power plug and wall outlet without removing
dust may result in fire.

The risk of electric shock exists.

The cable may be broken, leading to a risk of fire and
electric shock.

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.
