SAFETY AND IMPORTANT WARNING ITEMS
SAFETY WARNINGS
[1] MODIFICATIONS NOT AUTHORIZED BY
KONICA MINOLTA BUSINESS TECHNOLOGIES, INC.
Konica Minolta brand copiers are renowned for their high reliability. This reliability is achieved through high-quality design
and a solid service network.
Copier 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, unau-
thorized 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.
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, sol-
der 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.

must not exceed the rating of the wall outlet.
If excessive current flows in the wall outlet, fire may result.
kw
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.
• 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 plugs on both ends) 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 copier, be sure to
observe the following precautions:
a. Make sure the copier-side power plug is securely inserted in the socket
on the rear panel of the copier.
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 copier 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.
S-3
SAFETY AND IMPORTANT WARNING ITEMS
WARNING: Power Plug and Cord
• 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.
WARNING: Wiring
• Never use multi-plug adapters to plug multiple power cords in the same out-
let.
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.
WARNING: Ground Lead
• Check whether the copier is grounded properly.
If current leakage occurs in an ungrounded copier, you may suffer electric
shock while operating the copier. Connect the ground lead to one of the
following points:
a. Ground terminal of wall outlet
b. Ground terminal for which Class D work has been done
S-4
SAFETY AND IMPORTANT WARNING ITEMS
WARNING: Ground Lead
• Pay attention to the point to which the ground lead is connected.
Connecting the ground lead to an improper point such as the points listed
below results in a risk of explosion and electric shock:
a. Gas pipe (A risk of explosion or fire exists.)
b. Lightning rod (A risk of electric shock or fire exists.)
c. Telephone line ground (A risk of electric shock or fire exists in the case
of lightning.)

[3] MEASURES TO TAKE IN CASE OF AN ACCIDENT
1. If an accident has occurred, the distributor who has been notified first must immediately take emergency measures to
provide relief to affected persons and to prevent further damage.
2. If a report of a serious accident has been received from a customer, an on-site evaluation must be carried out quickly
and KMBT must be notified.
3. To determine the cause of the accident, conditions and materials must be recorded through direct on-site checks, in
accordance with instructions issued by KMBT.
4. For reports and measures concerning serious accidents, follow the regulations given in “Serious Accident Report/
Follow-up Procedures”.
[4] CONCLUSION
1. Safety of users and customer engineers depends highly on accurate maintenance and administration. Therefore,
safety can be maintained by the appropriate daily service work conducted by the customer engineer.
2. When performing service, each copier on the site must be tested for safety. The customer engineer must verify the
safety of parts and ensure appropriate management of the equipment.

SAFETY INFORMATION
IMPORTANT INFORMATION
The Center for Devices and Radiological Health (CDRH) of the U.S. Food and Drug Administration implemented
regulations for laser products manufactured since August 1, 1976. Compliance is mandatory for products mar-
keted in the United States.
This copier is certified as a “Class 1” laser product under the U.S.
Department of Health and Human Services (DHHS) Radiation Performance Standard according to the Radiation
Control for Health and Safety Act of 1968. Since radiation emitted inside this copier is completely confined within
protective housings and external covers, the laser beam cannot escape during any phase of normal user opera-
tion.

SAFETY CIRCUITS
SAFETY AND IMPORTANT WARNING ITEMS
This machine is provided with the following safety circuits
to prevent machine faults from resulting in serious acci-
dents.
[1] Overall protection circuit
[2] L2 and L3 (fixing heater lamps) overheating
prevention circuit
These safety circuits are described below to provide the
service engineer with a renewed awareness of them in
order to prevent servicing errors that may impair their
functions.
[1] Overall Protection Circuit
CBR1
NF
CBR2
1. Protection by CBR1 and CBR2 (circuit breakers)
CBR1 and CBR2 interrupt the AC line instanta-
neously when an excessive current flows due to a
short in the AC line.
CAUTION: The CBR1 and CBR2 functions must not be deactivated under any circumstances.
[2] Protection by L2, L3 and L4 (fixing
heater lamps) overheating prevention
circuit
DCPS
RL1
PRCB
RL1
TH2
Control section
AC driver section
TH1
1. Protection by software
The output voltage from TH1 (fixing temperature
sensor 1) is read by the CPU. If this voltage is
abnormal, L2 (fixing heater lamp 1), L3 (fixing
heater lamp 2), L4 (fixing heater lamp 3) and RL1
(main relay) are turned OFF.
CAUTION: Do not change the gap between the roller and TH1. When replacing TH1, check the specified mounting dimensions. The RL1 function must not be deactivated under any circumstances.
TS2
TS1
L2
L3
L4
S-11
SAFETY AND IMPORTANT WARNING ITEMS
2. Protection by the hardware circuit
The output voltages from TH1 and TH2 (fixing
temperature sensors) are compared with the abnor-
mality judgment reference value in the comparator
circuit. If the output voltage from TH1 or TH2
exceeds the reference value, L2 (fixing heater lamp
1), L3 (fixing heater lamp 2), L4 (fixing heater
lamp 3) and RL1 (main relay) are turned OFF in
hardware means.
CAUTION: Periodically check the TH2 face contact­ing the roller, and replace TH2 if any abnormality is detected. Since TH1 (fixing temperature sensor) face does not contact the roller, check the distance from the roller and the sensor orientation if any abnormality is detected. The RL1 function must not be deactivated under any circumstances.
3. Protection by TS1 (thermostat/U) and TS2 (thermostat/L)
When the temperature of the fixing roller (upper/
lower) exceeds the specified value, TSs are turned
OFF, thus interrupting the power to L2 (fixing
heater lamp/1), L3 (fixing heater lamp/2), and L4
(fixing heater lamp/3) directly.
CAUTION: Do not use any other electrical conductor in place of TS1 and TS2. Do not change the distance between the roller and TS (thermostat).
