SAFETY PRECAUTIONS
SAFETY PRECAUTIONS
Installation Environment
Safety considerations usually are directed toward
machine design and the possibility of human error. In
addition, the environment in which a machine is operated must not be overlooked as a potential safety
hazard.
Most electrical equipment is safe when installed in a
normal environment. However, if the environment is
different from what most people consider to be normal, it is conceivable that the combination of the
machine and the room air could present a hazardous
combination. This is because heat (such as from
fusing units) and electrical arcs (which can occur
inside switches) have the ability to ignite flammable
substances, including air.
When installing a machine, check to see if there
is anything nearby which suggests that a poten-
tial hazard might exist. For example, a laboratory
might use organic compounds which, when they
evaporate, make the room air volatile. Potentially dangerous conditions might be seen or smelled. The
presence of substances such as cleaners, paint thinners, gasoline, alcohol, solvents, explosives, or similar items should be cause for concern.
If conditions such as these exist, take appropriate
action, such as one of the following suggestions.
effect may be caused by altering any aspect of the
machine’s design. Such changes have the potential
of degrading product performance and reducing
safety margins.
For these reasons, installation of any modification not
specifically authorized by Konica Business Machines
U.S.A., Inc., is strictly prohibited.
The following list of prohibited actions is not all-inclusive, but demonstrates the intent of this policy.
• Using an extension cord or any unauthorized
power cord adapter.
• Installing any fuse whose rating and physical size
differs from that originally installed.
• Using wire, paper clips, solder, etc., to replace or
eliminate any fuse (including temperature fuses).
• Removing (except for replacement) any air filter.
• Defeating the operation of relays by any means
(such as wedging paper between contacts).
• Causing the machine to operate in a fashion other
than as it was designed.
• Making any change which might have a chance
of defeating built-in safety features.
• Using any unspecified replacement parts.
• Determine that the environment is controlled
(such as through the use of an exhaust hood) so
that an offending substance or its fumes cannot
reach the machine.
• Remove the offending substance.
• Install the machine in a different location.
The specific remedy will vary from site to site, but the
principles remain the same. To avoid the risk of injury
or damage, be alert for changes in the environment
when performing subsequent service on any machine, and take appropriate action.
Unauthorized Modifications
Konica copiers have gained a reputation for being
reliable products. This has been attained by a combination of outstanding design and a knowledgeable
service force.
The design of the copier is extremely important. It is
the design process that determines tolerances and
safety margins for mechanical, electrical, and electronic aspects. It is not reasonable to expect individuals not involved in product engineering to know what
General Safety Guidelines
This copier has been examined in accordance with
the laws pertaining to various product safety regulations prior to leaving the manufacturing facility to
protect the operators and service personnel from
injury. However, as with any operating device, components will break down through the wear-and-tear of
everyday use, as will additional safety discrepancies
be discovered. For this reason, it is important that the
technician periodically performs safety checks on the
copier to maintain optimum reliability and safety.
The following checks, not all-inclusive, should be
made during each service call:
CAUTION: Avoid injury. Ensure that the copier is
disconnected from its power source before continuing.
• Look for sharp edges, burrs, and damage on all
external covers and copier frame.
• Inspect all cover hinges for wear (loose or broken).
• Inspect cables for wear, frays, or pinched areas.
v
Page 8
SAFETY PRECAUTIONS
• Ensure that the power cord insulation is not damaged (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 alcohol, 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 applying power or installing covers.
Summary
It is the responsibility of every technician to use professional 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 present, 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!

DESCRIPTION OF EACH MECHANISM AND CONTROL
6
6-1. Exit/Turnover Switching Mechanism
• The exit/turnover switching mechanism uses the Exit/Turnover Switching
Finger that is moved to change the paper path either for exit or turnover.
• When in the Exit mode or when the copy is to be fed out in the Duplex
mode, Exit/Turnover Switching Solenoid SL1 remains deenergized and the
copy moves above the Exit/Turnover Switching Finger and is fed out of the
copier by the Exit Rollers.
• When the copy is to be turned over in the Duplex mode, SL1 is energized
and the copy moves beneath and along the Exit/Turnover Switching Finger
and is fed by the Vertical Transport Rollers of the Duplex Unit down
towards the turnover section.
• As noted above, SL1 moves the Exit/Turnover Switching Finger to change
the paper path. It is energized when a LOW signal from the copier is input
to PJ2A-1 on PWB-A.

6-2. Fuser Oil Cleaning Mechanism
• Since fuser oil is on the front side of the paper after the fusing process, it is
transferred onto the surface of the PC Drum via the Transfer Film during
the second copy process of 2-sided copying, which results in image
problems. Silicone rubber rollers are used as the Vertical Transport
Rollers of the Duplex Unit. They function to recover fuser oil from the
surface of the paper.
6-3. Paper Standby Control
• In a Duplex mode making two or more copy sets of an original set (which
involves two-sheet paper attraction), two sheets of paper are present in the
Duplex Unit, one waiting for take-up from the Duplex Unit following the
turnover cycle and the other remaining stationary at the vertical transport
section. (See "7. OPERATION AND CONTROL" that follows.)
• There is no problem with the paper waiting for take-up from the Duplex Unit
as it is driven independently of the copier drive. The paper at the vertical
transport section is, however, being transported and the drive from the
copier must be cut off. To accomplish this, Vertical Transport Clutch CL1
is mounted on the shaft of the Vertical Transport Roller and it couples or
cuts off the copier drive to the roller.
• CL1 is energized to stop the Vertical Transport Roller rotation when a LOW
signal from the copier is input to PJ2A-4 on PWB-A.
M-7
Page 18
6-4. Switchback Operation (Turnover)
• The Turnover Roller turns forward to transport the copy to the turnover
section and, as soon as the trailing edge of the copy moves past
Switchback Sensor PC1, it stops turning. The Turnover Roller then turns
backward to turn over the copy and feed it back into the copier.
• The drive for the Turnover Roller comes from Turnover Motor M1 which is
turned forward, backward, or stopped by the signals fed from the copier as
follows.

7-1. No. of Multiple 2-Sided Copies
• Copier does not store in memory the image data it scanned. For these
reasons, the number of multiple 2-sided copies that can be made varies
depending on the paper size, copying mode, and whether the Duplexing
Document Feeder is used or not. Here are the details.

TROUBLESHOOTING
General Precautions
CAUTION
1. When servicing the unit with its covers removed, use utmost care to prevent
your hands, clothing, and tools from being caught in revolving parts.
2. Before attempting to replace parts and unplugging connectors, make sure that
no power is being supplied from the copier.
Important
1. Never create a closed circuit across connector pins except those authorized in
the text and on the PWB.
2. When creating a closed circuit and measuring a voltage across connector pins
specified in the text, be sure to use the green wire (GND).
3. Keep all disassembled parts in good order and keep tools under control so that
none will be lost or damaged.
Reading the Text
1. If a component on a PWB or any other functional part including a motor is
defective, the text only instructs you to replace the whole PWB or functional
part and does not give troubleshooting procedure applicable within the
defective part.
2. The text assumes that there are no breaks in the harnesses and cords and all
connectors are plugged into the right positions.

How to use this catalog
This parts catalog includes illustrations and part numbers for all replacement parts and assemblies used in this model.
Model-specific parts are identified in the illustrations with reference
numbers. Use the reference number to locate the corresponding part
number on the facing page.
Common hardware items, such as screws, nuts, washers, and pins,
are identified in the illustrations with reference letters. Use the reference
letter to locate the corresponding part number on the hardware listing in
the lower right hand corner of the facing page.
If you know a part number, but don’t know where the part is used, use
the numerical index to determine the page number and reference number for that part. Because some common parts are used in several
places, there may be more than one entry. Refer to the illustrations to
see where the part may be used.
If you know a part’s description, but don’t know where to look to find
the part number, use the alphabetical index to determine likely page and
reference numbers. Then look at the illustrations to determine that you
have identified the correct part. Locate the part number using the listing
on the opposite page.
Retail pricing that appears with the numerical index, while valid when
this catalog was printed, is subject to change without notice. The prices
are only suggested prices and are provided only for reference. Dealers
may determine their own selling prices. For up-to-date pricing, refer to
current Konica price lists or contact the Konica Parts Distribution Center.
