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 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, make the room air volatile. Potentially dan ­gerous 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 elec ­tronic aspects. It is not reasonable to expect individu ­als 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, 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 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

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 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 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!

ORIGINAL CONVEYANCE PROCESS

As illustrated below, the DF-314 is made up of a original
feed section, conveyance section, original exit section and
reversal section.

Conveyance
section

Slit glass
(Read section)

Original feed section

Reversal section

Original exit section

With the originals set face-up on the original feed tray,
they are fed from the topmost original. Rather than being
conveyed to an original glass surface, the originals that
are fed in and read when they pass a slit glass placed in
the conveyance path.

There are 3 modes in the DF-314 operation mode, single­side original copy mode, double-side original copy mode,
and mixed original copy mode, and the conveyance path
differs according to each mode.

When PS311 turns ON, the original is re-fed by the
registration roller and conveyed to the original
conveyance roller. The original conveyance roller
conveys the original to the position where PS312 (original
feed PS) turns ON.

Conveyance rollers

The conveyance roller turns, and scanning starts. If there
is another original waiting, it is pre-fed at this point.

The scanning of the original is conveyed out when the
original passes over the slit glass. The original which has
been read is exited to the original exit tray by the original
exit roller with the exit SD OFF (i.e. with the exit guide
raised).

Single-Side Original Copy Mode

(Single-side to single-side copy, single-side to
double-side copy)

The original that has been set in the paper feed tray is
lifted by the paper lift-up plate so it comes into contact with
the original feed roller. The original feed roller and the
separation roller pre-feed to the position where P311
(original registration PS) turns on.

Double-side Original Copy Mode

(Double-side to single-side copy, double-side to
double-side copy)

The original set in the original feed tray is pre-fed to the
position where PS311 (original registration PS) turns ON
by the original feed roller and the separation roller. When
PS311 turns ON, the reversal guide opens, the
registration roller conveys the original to the reversal
section, and the reversal roller conveys the original into
the interior of the reversal section.

Reversal guide

Original registration PS (PS311)

After the specified period from when PS311 detects the
training edge of the original and goes OFF, the original is
conveyed to the stop position at the front edge of the
reversal guide. As the original has been reversed at this
point, the reversal roller is made to rotate in reverse and
it conveys the original to the original conveyance roller. If
there is another original waiting, it is pre-fed at this
timing.

Registration roller

Reversal roller

The exit SD comes ON (the exit guide is lowered) when
scanning of the rear side of the original begins, and the
original is again conveyed to the reversal roller. When
PS312 detects the rear edge of the original and turns
OFF, the original is conveyed as far as the stop position in
front of the reversal gate by the timer. The original has
been reversed once again by this point so is conveyed to
the original conveyance roller. The original conveyance
roller conveys the original and reading of the original face
side starts.

Mixed Original Copy Mode

The mixed original copy mode supports both same-series
originals and different series originals, but as size
detection is performed in PS311 ON time, size detection is
performed before reading.

After the size of the original is detected, the original stops
at the reversal position. Subsequently, operation is the
same as that of the two-sided copy mode.

1. Operation
a. Original feed

Original feed is started by the transmission of the
M301 drive power to the original feed roller,
separation roller and paper lift-up plate.

b. 1st original pre-feed

When the copy button is pressed, the M301 starts
original pre-feed, and when the conveyed original
arrives at PS311, M301 stops temporarily after a
specified time. M301 then rotates in reverse, turning
the registration roller so that feeding starts again.
The original passes PS311, so that PS311 turns
OFF. A predetermined time interval after PS311
turns OFF, M301 also turns OFF.

c. 2nd original pre-feed

When there is still an original in the original feed tray,
M301 starts after a specified time after PS311 has
turned OFF, and starts the pre-feed from after the
second sheet. The original is conveyed in the same
way as in the 1st. original pre-feed.

d. Scanning operation (except last original)

When the original arrives at PS311, M302 starts after
a specified time has elapsed and the original is
conveyed to the read section.

Scanning of the original is achieved when the
original passes over the surface of the slit glass of
the main body optical section.

When the original arrives at PS312, scanning is
started after a specified time has elapsed, and when
PS312 turns OFF after the original has passed,
scanning is stopped after the lapse of a fixed period
of time.

e. Scanning operation (last original)

During the scanning operation, when PS301(no
original detect PS) turns OFF, the original currently
being scanned is judged to be the last original. When
the last original has passed PS311, M301 turns OFF
after the lapse of a fixed period of time, and when the
original has passed PS303 (original exit PS), M302
turns OFF after a specified time.

1. Operation
a. Original exit operation

During single side copying and face side copying in
double-side copying, the exit guide is raised because
SD303 is OFF. For this reason, an original which has
been read is conveyed to the exit section.

b. Reversal original exit operation

During back side copying in double side copying, the
original is conveyed to the scanning section by
reverse rotation of M303 and nomal rotation of M302.
When PS312 turns ON, SD302 turns OFF, and
reversal roller paper pressure conveys the freed
original to the reversal section.

c. Reversal original feed operation

After PS312 has detected the rear edge of the
original, SD302 turns ON after a specified time has
elapsed and the reversal roller applies pressure
(seizes, pinches) to the original. After that, M303
stops, but then immediately reverses and starts the
original feed operation of the original face side scan.

motor) stops.

e. Overlap control

When scanning of the back side of the first original
sheet has been completed and the leading edge of
the original fed from the reversal section reaches
PS312, M301 turns ON and feeding of the second
original starts. At this time, the SD302 goes OFF,
causing the pressure on the reversal roller and the
paper exit roller to be released. This enables the first
and second originals to pass over each other in
opposite directions in the reversal unit.

MAIN BODY

Size detection on an original set in the original feed tray is
performed by PS306 (original size detect PS1), PS307
(original size detect PS2), and VR301 (size detect VR).

Note that the DF CB includes internal nonvolatile memory
that stores timing data, size-detection reference values,
and other such data.

b. Original size detection in mixed-original

modes and Z-fold-original modes (1st
sheet)

(1) Drum axis direction size detection

The width of the maximum sized original being
mixed-loaded is detected by the position of the
VR301 guide plate.

(2) Size detection in original feed direction

Original feed direction size is detected during PS311
ON time (the time taken by the original to pass
PS311).

(3) Operation of size detection in original feed

direction

When original re-feed is started by the registration
roller, when a specified time has elapsed after
PS311 turning ON, M303 (original reversal motor)
turns ON and conveys the original to the reversal
section.

PS311 (Original registration PS)

1. Operation
a. Normal copy mode

The DF CB detects the original size when the signals
described below combine.

(1) Drum axis direction size detection

VR301 resistance value changes in the position
where the guide plate contacts VR301. The width of
the original is detected by the resistance value.

(2) Size detection in original feed direction

The length of the original is detected by the ON/OFF
states of PS306 and PS307.

Conveyance to the scanning section is performed by
M303 reverse rotation.

Conveyance or scanning thereafter for both single
and double-sided originals is performed by the same
operation as for double-side copy mode. However in
single-side copying, the back side of the original
passes the scanning section without being scanned
and is conveyed to the reverse section.

Original size detection operation after the 2nd.
original starts after the completion of the exit of the
first original.

PARTS CATALOG

Model

DF-314

SEPTEMBER 2002

THIRD EDITION

KONICA BUSINESS TECHNOLOGIES, INC.

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.

How to order parts

Use standard Konica parts ordering procedures to obtain these parts.
For ordering options, contact Konica’s Parts Distribution Center.

When ordering parts, be sure to specify part numbers exactly as listed in
this catalog.

NOTE: Electrical parts may include previously used components.
