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 potential 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.

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!

ORIGINAL CONVEYANCE PROCESS

As the figure below shows, the DF-315 is composed of the paper feed section, conveyance section, reversal section, and paper exit section.

Conveyance section

Paper feed section

Single Side Original Copy Mode

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

The originals set in the paper feed tray are fed by means of the paper feed roller and separation roller to the position where original registration PS (PS306) goes on.

DF-315

Paper exit section

Reversal section

Slit glass (Read section)

The originals, which have been placed in the paper feed tray with the front side facing up, are fed starting with the topmost original. Originals that are fed are not conveyed to the original glass. Reading is carried out as the original passes by the slit glass section set midway through the conveyance path.

The operational modes of the DF-315 include three modes: (a) single side original copy mode, (b) double side original copy mode, (c) mixed original copy mode. The conveyance path is different for each mode.

Separation roller

Registration roller

Original registration PS

Paper feed roller

When original registration PS goes on, pre-feed is carried out by the registration roller and the original is conveyed to the conveyance roller. The conveyance roller conveys the original to the position where original feed detect PS (PS308) goes on. The original stops at the scanning standby position.

When scan is started, the conveyance roller rotates again in the forward direction to convey the original. If there is another original at this time, pre-feed is carried out.

Reading of the original is carried out when the original passes over the slit glass. Originals which have been read are conveyed around the circumference of the conveyance roller by closing of the flapper and are ejected to the paper exit section via the paper exit roller.

Double Side Original Copy Mode

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

The conveyance operation from feeding of the double sided original to the front side scanning standby position is the same as that for the single side original copy mode.

When scanning starts and reading of the front side is completed, the original is conveyed to the reversal section when the flapper opens and the paper exit path is blocked.

When original reverse detect PS (PS309) detects the leading edge of the original that has been conveyed to the reversal section and goes ON, pressure is applied to the pressure pulley. As a result, the reversal roller and pressure pulley clasp the original on both sides and convey it to the inside of the reversal section.

When original reverse detect PS (PS309) detects the trailing edge of the original and goes OFF, the reversal roller rotates in the reverse direction to feed the original from the reversal section to the conveyance roller. Since the original passes over the top of the flapper at this time, the front and back sides are reversed and the original is sent to the conveyance roller. The conveyance roller conveys the original to the scanning standby position.

Mixed Original/Z-Fold Original Mode

In the mixed original mode (can handle both same series and different series of originals) and the Z-fold original mode, the original size in the sub-scanning direction is determined by to the ON time of original registration PS (PS306), hence size detection takes place before the scanning operation. This operation takes place for all originals in the mixed original mode, and only for the first original in the Z-fold original mode.

After size detection is completed, the original stops at the scanning standby position. The subsequent operations are the same for all copy modes. For details of the size detection process, refer to [5] "Original Size Detection Control" in "PAPER FEED/PAPER EXIT SECTION".

Paper feed takes place by transmitting the drive force of motor M302 (original feed) to the paper feed roller and separation roller. Conveyance takes place by transmitting the drive force of motor M301 (original conveyance) to the conveyance roller. M301 and M302 are controlled by the DFCB (RADF control board).

1. Operation

a. Sensor adjustment when the power is ON.

When SW2 (sub power) is ON, a sensitivity PS306 (original registration) and PS308 (original feed detect) is adjusted automatically. However, if the RADF open/ close cover is open or an original is inside of the RADF, there will be no automatic adjustment.

b. Original pressure operation

When a control signal from the main body is received, CL301 (original pick-up) goes ON, and after the specified time M302 starts to rotate in the forward direction. This causes the paper feed roller to be lowered, applying pressure to the original. After the specified time, M302 and CL301 go OFF, but the pressure on the original is maintained.

Page 19

DF-315

c. Paper feed operation

When CL302 (original feed) goes ON, the driving force of M302 (original feed) is transmitted to the paper feed roller and the separation roller. CL302 goes ON at the same time as M302 performs forward rotation. When M302 switches from forward to reverse rotation, paper feed starts. When PS306 (original registration) goes ON, the reverse rotation of M302 is switched OFF after the specified time.

d. Pre-feed of first sheet

When the reverse rotation of M302 stops, the motor starts again to rotate in forward direction after the specified time. This causes the original to be moved to the conveyance roller. At the specified time after forward rotation of M302 has started, M301 (original conveyance) goes ON and moves the original from the conveyance roller to the scanning standby position. When PS308 (original feed detect) detects the leading edge of the original and turns ON, CL302 and M302 go OFF. After the specified time, M301 slows down and then goes OFF. At this point, the original still moves a small distance further due to the inertia of the conveyance roller and then stops. This is the scanning standby position.

h. Original pressure release

When M301 completes the scanning operation for the last original and goes OFF, CL301 and M302 go ON which causes the original pressure to be released. After the specified time, CL301 and M302 go OFF.

e. Pre-feed of second and further sheets

The forward rotation of M302 starts the pre-feed process of the following original, but because the motor immediately goes OFF, the original temporarily stops before reaching the conveyance roller. When M301 begins the scanning operation, the forward rotation of M302 starts again. Pre-feed of the original then is carried out while the preceding original is being scanned.

f. Scanning operation (except last original)

At the specified time after M301 goes OFF, it goes ON again and conveys the original over the slit glass areaof the main body, where scanning is performed. When PS306 detects the trailing edge of the original that is being scanned and goes OFF, CL302 again goes ON

g. Scanning operation (last original)

During scanning, when M301 is ON and one of the sensors PS302 (original size detect 1), PS303 (original size detect 2), or PS305 (no original detect) goes OFF, the original currently being scanned is the last one. A sensor that is used to judge the last original differs depending on the original size. When PS307 (original exit detect) goes OFF, M301 also is switched OFF after the specified time.

1. Operation

a. Sensor adjustment when the power is ON.

When SW2 (sub power) is ON, a sensitivity of PS309 (original reverse detect) is adjusted automatically. However, if the RADF open/close cover is open or an original is in the inside of the RADF, there will be no automatic adjustment.

b. Paper exit operation

In single-sided copy mode and when copying the reverse side of a sheet in duplex copy mode, SD301 is OFF and the flapper is closed. The original is therefore conveyed to the paper exit section after scanning.

c. Reversal paper exit operation

When copying the first side of a sheet in duplex copy mode, at the specified time after M301 (original conveyance) goes ON and scanning starts, SD301 goes ON and the flapper opens. This causes the original to be sent to the reversal section after scanning. At the same time as SD301 goes ON, M302 (original feed) starts reverse rotation and the drive force is transmitted to the reversal roller. When PS309 detects the leading edge of the original and goes ON, the SD302 goes ON after the specified time and applies pressure to the pressure pulley. As a result, the original which has been conveyed to the reversal section is caught between the reversal roller and pressure pulley, and conveyed to the inside of the reversal section.

d. Reversal feed operation

When PS309 detects the trailing edge of the original and goes OFF, both the M301 and M302 go OFF after the specified time, and conveyance operation of the original is stopped. After a predetermined OFF interval, M302 starts reverse rotation and feeds the original to the conveyance roller side of the reversal section. At this time, PS309 again goes ON and SD302 goes OFF after the specified time. M302 goes OFF after the specified time from PS309 goes OFF.

e. Pre-feed operation of next original when reading

back side of original

When PS309 goes OFF, M301 and M302 start forward rotation after the specified time, and next original pre-feed is carried out.

1. Operation

a. Normal copy mode

The DFCB detects the original size from the combination of the following signals.

(1) Detection of size in the main scanning direction

The guide plate is connected to VR301. The resistance of VR301 varies according to the position of the guide plate, enabling the size of the original in the main scanning direction to be detected.

(2) Detection of size in the sub-scanning direction

The size of the original in the sub-scanning direction is detected according to the combination of the ON/ OFF status of PS302 and PS303.

b. Original size detection in the mixed original/Z-

fold original mode

(1) Detection of size in the main scanning direction

The size of the largest original of mixed size originals in the main scanning direction is detected according to the position of the guide plate.

(2) Detection of size in the sub-scanning direction

The size of the original in the sub-scanning direction is detected according to the time at which PS306 (original registration) goes ON after the original is fed from the registration roller.

(3) Size detection process in the sub-scanning direction

When original pre-feed is started by the registration roller, M301 (original conveyance) rotates in the forward direction after the specified time from when PS306 goes ON, causing the original to be conveyed to the paper exit section. M301 continues to rotate in the forward direction until PS306 detects the trailing edge of the original and goes OFF. The size of the original in the sub-scanning direction is detected according to the ON time of PS306.

The size of the original placed in the paper feed tray is detected by PS302 (original size detect 1), PS303 (original size detect 2), and VR301 (original size detect). PS302, PS303, and VR301 are controlled by the DFCB (RADF control board) via the PTBD (Paper tray board). Inside the DFCB is a non-volatile memory for recording the timing data and original size detection threshold values.

M301 (original conveyance) rotates in the reversal direction after the specified time from PS306 (original registration) goes OFF and returns the leading edge of the original that has been conveyed to the paper exit section to the scanning standby position. The trailing edge of the original which has been returned is conveyed to the exit section due to the configuration of the conveyance section. The reversal rotation of the M301 stops after the specified time from PS308 (original feed detect) detects the leading edge of the original and goes ON.

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.
