SAFETY WARNINGS
[1] Modifications Not Authorized by
Konica Minolta
Konica Minolta equipment is renowned for their high
reliability. This reliability is achieved through high-quality
design and a solid service network.
Unauthorized modifications involve a high risk of degrad-
ing performance and safety. Such modifications are there-
fore strictly prohibited. The points listed below are not
exhaustive, but they illustrate the reasoning behind this
policy.
PROHIBITED ACTIONS :
(1) Using extension cables or a different power cord
than specified by Konica Minolta.
(2) Using other fuses than specified by Konica
Minolta. Safety will not be assured, leading to a
risk of fire and injury.
(3) Disabling fuses or bridging fuse terminals with
wire, metal clips, solder or similar. (This applies
also to thermal fuses.)
(4) Removing air filters (except for replacement).
(5) Disabling relay functions (such as wedging pa-
per between relay contacts, etc.).
(6) Disabling safety functions (interlocks, safety cir-
cuits, etc.). Safety will not be assured, leading to
a risk of fire and injury.
(7) Performing actions to equipment not described
in the instruction manual or the service hand-
book.
(8) Using parts other than specified by Konica
Minolta.
[2] Checkpoints When Performing On-
site Service
Konica Minolta equipment is extensively tested before
shipping, to ensure that all applicable safety standards
are met, in order to protect the customer and customer
engineer 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 customer engineer must perform regular safety checks.
1. Advance Preparation for Safety Checks
CAUTION:
(1) Wear clothing that facilitates work and is de-
signed for safety.
(2) Carry out all procedures carefully to prevent in-
jury.
(3) Be sure to disconnect the power cord of the
equipment from the AC outlet.
Simply turning off the power switch is not suffi-
cient, because paper feed units or other electri-
cal equipment may be powered also when the
power switch is turned off.
(4) Proceed with special care when performing op-
eration checks or adjustment while the unit is
powered. When carrying out operation checks or
adjustment while external covers are removed,
the risk of electrical shock exists when touching
parts which carry high voltage or electrical charge.
The risk of injury exists when touching moving
parts such as gears or chains.
2. Safety Checkpoints
The following list is not exhaustive, but it includes actions
which must be carried out at every on-site service.
CAUTION:
(1) Check external covers and the frame for sharp
edges, burrs, or nicks.
(2) Check external covers and hinges for loosening
or damage.
(3) Check wiring for squeezing or damage.
(4) Check power cord for insulation problems (con-
ductor must not be exposed).
(5) Check power cord and cable ties etc. for loosen-
ing from frame.
WARNING:
(1) Verify that the equipment is properly grounded. If
a problem is detected, establish a proper ground
connection.
(2) Connecting the ground lead to an improper point
such as listed below results in a risk of explosion
and electric shock.
Unsuitable ground points:
- Gas pipe
- Lightning rod
- Telephone line ground
- Plastic water pipe or water pipe or faucet that
has not been approved by authorities for
grounding use
3. Description of Safety Checks
CAUTION:
(1) Before performing safety check work, read all
relevant documentation (service handbook, tech-
nical notices, etc.) and proceed according to the
prescribed procedure, using only the prescribed
tools. Do not carry out any adjustments not
described in the documentation.
