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.
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
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.
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.

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.


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!

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

Registration roller

Conveyance rollers
Reversal section Original exit section Original registration PS (PS311)
Slit glass (Read 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.

Original feed PS (PS312)

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).

Next original

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.
Slit glass Registration roller Separation roller Original feed roller
Original exit roller Exit guide
Paper lift-up plate Original registration PS (PS311)
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 Registration 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.

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. The original conveyance roller conveys the original to the position where PS312 turns ON and the reading of the original back 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. Refer to "ORIGINAL FEED/REVERSAL/ORIGINAL EXIT SECTION/Original size detection control" for size detection operation.

DF-314 1. a. Operation 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.

Signals Input signals

(1) PS301(PS301 -> DF CB)
Original feed tray no-paper detection signal [L] : Original

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.

[H] : No original

(2) PS303(PS303 -> DF CB)
Original exit section original detection signal [L] : No original [H] : Original
(3) PS311(PS311 -> DF CB)
Original conveyance roller entrance original detection signal [L] : No original [H] : Original

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.
(4) PS312(PS312 -> DF CB)
Original detection signal from detector in front of scan position [L] : No original [H] : Original
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.
(5) M TXD (MAIN BODy -> DF CB)
Serial data line; informs RADF of the operating state of the main body's CB
Transmission request signal from main body to RADF
Transmission OK signal from main body to RADF

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.

The exit guide used in exit path switching is driven by the SD303 (exit SD). Reversal conveyance drive in double-side copy mode is performed by the M303 (original reversal motor). The reversal roller pressure/freeing used in reversal original feed is performed by the SD 302 (roller pressure SD). M303, SD302 and SD303 are controlled by the DF CB (RADF control board).
DF-314 1. a. Operation 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.

Signals Output signals

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.

(2) SD302 (DF CB -> SD302)
SD302 drive control signal [L] : ON
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.

[H] : OFF

(3) SD303 (DF CB -> SD303)
SD303 drive control signal [L] : ON [H] : OFF
Pre-feed operation of next original when reading back side of original
PS311 turns OFF once the first original has passed, and after a specified period of time has elapsed, starts the pre-feed operation for the 2nd. original. After the elapse of a specified time after the 2nd. original has arrived at PS311, M301 (original feed motor) stops.

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.
Original Size Detection Control
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)
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.
Operation Normal copy mode
The DF CB detects the original size when the signals described below combine.
VR301 resistance value changes in the position where the guide plate contacts VR301. The width of the original is detected by the resistance value.

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

Description F26-1 at power up. Solution CAUSE: The TDS (Toner Density Sensor), in the developing unit, has detected a depletion of toner. Note: This may have been caused by the customer making an excessive amount of copies while the machine was out of toner. It may also be caused by a bound toner addition system. SOLUTION: Clean all toner from the toner recycle and toner supply assemblies. Confirm that the gear mesh between the toner supply auger drive gear and toner supply motor (M4) is flush. If toner supply conveyance is normal and the toner cavity is empty, install a new toner cartridge (Item #950236) and then perform the following diagnostic mode to replenish the developing unit with toner: 1. Access the 47 mode (power the copier ON while pressing the 4 and 7 keys). 2. Enter output code 54. 3. Press the START button. Note: Toner will now be added to the developing unit and stop automatically when target level is reached, although it will not run any longer than 3 minutes. 4. Power copier OFF/ON to return to normal copy mode. Note: Perform the following 25 mode software switch settings to minimize the amount of copies that can be made, prior to copy inhibit, when the ADD TONER message is displayed: 1. Access the 25 mode (hold down the 2 and 5 keys at power ON). 2. Select [1] (SOFTWARE SW). 3. Using the up and down arrows, scroll to the following software switches and set them as follows: a. 4-0 set to a 0 b. 4-1 set to a 0 c. 4-2 set to a 0 d. 4-3 set to a 0 6. Power OFF/ON to return to normal copy mode. Notes: 1. These setting will allow the ADD TONER message to be displayed immediately and only allow 100 copies to be thereafter. 2. Copier inhibit will automatically be released when a new toner cartridge is installed. 3. This solution identified as a common problem by Jim Wood, Konica BT Orlando.
