Konica Minolta KN-304, Service Manual

•

Ensure that the power cord insulation is not dam-
aged (no exposed electrical conductors).

•

Ensure that the power cord is properly mounted
to the frame by cord clamps.

•

Check the continuity from the round lug (GND) of
the power cord to the frame of the copier -- ensure
continuity. An improperly grounded machine can
cause an electrically-charged machine frame.

Safeguards During Service Calls

Confirm that all screws, parts, and wiring which are
removed during maintenance are installed in their
original positions.

•

When disconnecting connectors, do not pull the
wiring, particularly on AC line wiring and high
voltage parts.

•

Do not route the power cord where it is likely to
be stepped on or crushed.

•

Carefully remove all toner and dirt adhering to any
electrical units or electrodes.

•

After part replacement or repair work, route the
wiring in such a way that it does not contact any
burrs or sharp edges.

•

Do not make any adjustments outside of the
specified range.

Applying Isopropyl Alcohol

Care should be exercised when using isopropyl alco-
hol, due to its flammability. When using alcohol to
clean parts, observe the following precautions:

•

Remove power from the equipment.

•

Use alcohol in small quantities to avoid spillage
or puddling. Any spillage should be cleaned up
with rags and disposed of properly.

•

Be sure that there is adequate ventilation.

•

Allow a surface which has been in contact with
alcohol to dry for a few minutes to ensure that the
alcohol has evaporated completely before apply-
ing power or installing covers. 

Summary

It is the responsibility of every technician to use pro-
fessional skills when servicing Konica products. There
are no short cuts to high-quality service. Each copier
must be thoroughly inspected with respect to safety
considerations as part of every routine service call.
The operability of the copier, and more importantly,
the safety of those who operate or service the copier,
are directly dependent upon the conscientious effort
of each and every technician.

Remember...when performing service calls, use good
judgement (have a watchful eye) to identify safety
hazards or potential safety hazards that may be pre-
sent, and correct these problem areas as they are
identified -- the safety of those who operate the copier
as well as those who service the copier depend on it!
