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 oper-
ated 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 nor-
mal, 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,maketheroomairvolatile.Potentiallydan-
gerous conditions might be seen or smelled. The
presence of substances such as cleaners, paint thin-
ners, gasoline, alcohol, solvents, explosives, or simi-
lar items should be cause for concern.
If conditions such as these exist, take appropriate
action, such as one of the following suggestions.
•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 ma-
chine, and take appropriate action.
Unauthorized Modifications
Konica copiers have gained a reputation for being
reliable products. This has been attained by a combi-
nation 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 elec-
tronic aspects. It is not reasonable to expect individu-
als not involved in product engineering to know what
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-inclu-
sive, but demonstrates the intent of this policy.
•Using an extension cord or any unauthorized
power cord adapter.
•Installingany fuse whose rating andphysical 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).
•Causingthemachinetooperateinafashionother
than as it was designed.
•Making any change which might have a chance
of defeating built-in safety features.
•Using any unspecified replacement parts.
General Safety Guidelines
This copier has been examined in accordance with
the laws pertaining to various product safety regula-
tions prior to leaving the manufacturing facility to
protect the operators and service personnel from
injury.However,aswith any operating device, compo-
nents 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 continu-
ing.
•Look for sharp edges, burrs, and damage on all
external covers and copier frame.
•Inspect all cover hinges for wear (loose or bro-
ken).
•Inspect cables for wear, frays, or pinched areas.
v

•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
thepowercordtotheframe ofthecopier-- 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.
•Carefullyremovealltoneranddirtadheringtoany
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-
fessionalskillswhenservicingKonicaproducts.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...whenperformingservicecalls,usegood
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 -- thesafety of those who operate the copier
as well as those who service the copier depend on it!

■Product overview
●Capabilities of the IP-011
The Konica IP-011 printer controller allows you to use the Konica 7020 series copying machine as
a printer connected to computers and a network. It receives print jobs from computers and network
and converts them into image data (video data) that the Konica 7020 series copying machine prints
out.
The IP-011 printer controller is characterized as follows.
•Built in the Konica 7020 series copying machine.
•Host-base printer of Windows only.
•Printer status can be monitored and several settings can be changed from the
status monitor/Control Panel through parallel line.
•The drivers interfacing with Windows 95/98 and NT allow use of the functions
of the Konica 7020 series copying machine.
•The KN-304 network board allows use of the IP-011 as a network printer.
•Use of flash memory enables to upgrade the system software through the par-
allel port.
This Service Handbook describes hardware construction, disassembly and assembly procedures,
troubleshooting, and appendixes (upgrading firmware, error messages, etc).

Chapter 1 Overview
●Startup sequence of the 7020 series + IP-011 system
As the IP-011 is built in the 7020 series, supplying power to the IP-011 and its initialization starts as
soon as you turn on the copier. The startup sequence is as follows.
1. You turn on the copier.
Supplying power to start the IP-011 starts. Its CPU works to test the system memory
and the system program starts running.
2. The IP-011 performs system check.
3. On completion of system check, the controller’s icon appears on the copier LCD screen.
If printer mode is selected, a message “Ready to print” appears.
●Data processing of the IP-011 (See data flow.)
When you attempt to print a document data from a computer connected the IP-011, processing will
be made as follows.
1. The print job comes from the computer (or network) to the parallel port (or Ethernet port if
the KN-304 is used).
2. The CPU, mounted on IP-011, generates the bit map image of one page to another in the
image memory.
3. The bit map image is transferred in the form of video signals from the image memory to the
copier and printed.
