(Customer Maintenance Support)
CMS REPLACEMENT INSTRUCTIONS
1. Drum unit, Ozone filter, Toner filter

Introduction
CMS:
• The CMS(Customer Maintenance Support) isasystem that supportsthe customer who
conductsapartsreplacement operation by himself without getting an technical assis-
tance 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 youwant to employ the CMS, be sure to follow the instructionsgiven by the cus-
tomer engineer.
And also, when youconduct apart replacement operation, be sure to read each replace-
ment instruction and follow the specific instructionsgiven in it. For your safety while in the
replacement operation, be sure to keep thisCMSInstructionsfor Replacement safely,
and also be careful not to get it lost. Should it get lost, contact our service representative.

[1] MODIFICATIONSNOT AUTHORIZED BY KONICA MINOLTA
BUSINESS TECHNOLOGIES, INC.
KONICA MINOLTA brand productsare renowned for their high reliability. Thisreliability is
achieved through high-quality design and asolid service network.
Product design isahighly complicated and delicate process where numerous mechanical,
physical, and electrical aspectshave to be taken into consideration, with the aim of arriving
at proper tolerancesand safety factors. For thisreason, unauthorized modificationsinvolve
ahigh risk of degradation in performance and safety. Such modificationsare therefore
strictly prohibited. the pointslisted below are not exhaustive, but they illustrate the reason-
ing behind thispolicy.
SAFETY WARNINGS
Prohibited Actions
DANGER
•Using any cablesor power cord not specified by KMBT.
•Using any fuse or thermostat not specified by KMBT.
Safety will not be assured, leading to arisk of fire and
injury.
•Disabling fuse functionsor bridging fuse terminalswith
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 arisk of fire and
injury.
•Making any modification to the product unless instructed
by KMBT.
•Using partsnot specified by KMBT.

[2] POWER PLUG SELECTION
In some countriesor areas, the power plug provided with the product may not fit wall outlet
used in the area. In that case, it isobligation 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 meetsthe following
criteria:
- provided with aplug having configuration intended for
the connection to wall outlet appropriate for the prod-
uct’srated 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 meetsregulatory requirementsfor the area.
Use of inadequate cord set leadsto fire or electric shock.
•Attach power plug which meetsthe following criteria:
- having configuration intended for the connection to wall
outlet appropriate for the product’srated voltage and
current, and
- the plug has pin/terminal(s) for grounding, and
- meetsregulatory requirementsfor the area.
Use of inadequate cord set leadsto the product connect-
ing to inadequate power supply (voltage, current capacity,
grounding), and may result in fire or electric shock.
• Conductorsin the power cable must be connected to ter-
minalsof 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 safeguardswithin the
product, and resultsin fire or electric shock.

[3] CHECKPOINTSWHEN PERFORMING ON-SITE SERVICE
KONICA MINOLTA brand productsare extensively tested before shipping, to ensure that all
applicable safety standardsare 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 partswear 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 mainsvoltage isas 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 leadsto the product connecting to
inadequate power supply (voltage, current capacity,
grounding), and may result in fire or electric shock.
If proper wall outlet isnot 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 flowsin the wall outlet, fire may
result.
• If two or more power cordscan be plugged into the wall
outlet, the total load must not exceed the rating of the wall
outlet.
If excessive current flowsin the wall outlet, fire may
result.
•Make sure the power cord isplugged in the wall outlet
securely.
Contact problemsmay lead to increased resistance,
overheating, and the risk of fire.
• Check whether the product isgrounded properly.
If current leakage occursin 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
thisproduct, make sure the connector issecurely inserted
in the inlet of the product.
When securing measure isprovided, secure the cord with
the fixture properly.
If the power cord (inlet type) isnot connected to the prod-
uct securely, acontact problem may lead to increased
resistance, overheating, and risk of fire.
• Check whether the power cord isnot stepped on or
pinched by atable and so on.
Overheating may occur there, leading to arisk of fire.
• Check whether the power cord isdamaged. Check
whether the sheath isdamaged.
If the power plug, cord, or sheath isdamaged, replace
with anew 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 arisk of fire.
• Check whether dust iscollected 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 awet
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 arisk of fire and
electric shock.
