SAFETY WARNINGS
●MODIFICATIONS NOT AUTHORIZED BY Konica
Konica copiers are renowned for their high reliability. This reliability is achieved through high-quality
design and a solid service network.
Photocopier 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
ofdegrading performanceand safety. Suchmodifications aretherefore strictlyprohibited.Thepoints
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.
(2) Using other fuses than specified by Konica. Safety will not be assured, lead-
ing 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 paper between relay contacts,
etc.).
(6) Disabling safety functions (interlocks, safety circuits, etc.). Safety will not be
assured, leading to a risk of fire and injury.
(7) Performing actions to copier not described in the instruction manual or the
service handbook.
(8) Using parts other than specified by Konica.
●CHECKPOINTSWHEN PERFORMING ON-SITE SERVICE
Konica copiers are extensively tested before shipping, to ensure that all applicable safety stan-
dards are met, in order to protect the customer and customer engineer from the risk of injury.
However, in daily use, any electrical equipment will be subject to parts wear and eventual failure. In
order to maintain safety and reliability, the customer engineer must perform regular safety checks.
Caution :
(1) Wear clothing that facilitates work and is designed for safety.
(2) Carry out all procedures carefully to prevent injury.
(3) Be sure to disconnect the power cord of the copier and all optional equip-
ment from the AC outlet.
Simply turning off the power switch is not sufficient, because paper feed
units or other electrical equipment may be powered also when the power
switch is turned off.
(4) Proceed with special care when performing operation checks or adjustment
while the unit is powered. When carrying out operation checks or adjust-
ment 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.

Safety and Important Warning Items
The following list is not exhaustive, but it includes actions which must be carried out at every ser-
vice call. 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) Checkpower cordfor insulationproblems(conductor mustnot beexposed).
(5) Check power cord and cable ties etc. for loosening from frame.
Warning :
(1) Verify that the copier is properly grounded. If a problem is detected, estab-
lish a proper ground connection.
(2) Connecting the ground lead to an improper point such as listed below re-
sults 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
●PRECAUTIONS FOR ON-SITE SERVICE
Caution :
(1) Before performing maintenance work, read all relevant documentation (ser-
vice handbook, technical notices, etc.) and proceed according to the pre-
scribed procedure, using only the prescribed tools. Do not carry out any
adjustments not described in the documentation.
(2) If the power cord is damaged, replace it only with the specified power cord.
If the power cord insulation has been damaged and there are exposed sec-
tions, shortcircuits and overheating may occur, leading to a serious fire risk.
(3) Do not route the power cord so that it can be stepped on or pinched. Other-
wise overheating may occur, leading to a serious fire risk.
(4) When disconnecting any cables, always grasp the connector and not the
cable (especially in the case of AC and high-voltage leads).
(5) Carefully remove all toner remnants from electrical parts, electrodes, etc.
(6) Make sure that wiring cannot come into contact with sharp edges, burrs, or
other pointed parts.
(7) Double-check to make sure that all screws, components, wiring, connec-
tors, etc. that were removed for maintenance have been reinstalled in the
original location. (Pay special attention to forgotten connectors, pinched
cables, forgotten screws, etc.)
(8) When installation and preventive maintenance, verify that the power cord
has been securely plugged into the AC outlet. Contact problems may lead
to increased resistance, overheating, and the risk of fire.
Warning :
(1) Before disassembling or adjusting the optical unit or any parts that use a
laser, make sure that the power cord has been disconnected.
