Introduction
The cause of most accidents is failure to adhere to basic safety rules and observe safety instructions. It is important to prevent potential causes of accidents from occurring. In order to do so, read this manual carefully, and be sure to understand all the safety instructions and correct inspection and servicing procedures that it provides before beginning repair or servicing work. Repairing or servicing the machine with insufficient knowledge about it could lead to unforeseen accidents. It is not possible to anticipate and describe in a manual such as this every possible hazard that could arise in the course of repair and servicing. Therefore, besides observing the safety instructions marked in this manual and on the machine's labels, service personnel should be safety-conscious and take other safety precautions as necessary. When performing repair or service work not covered by this manual, you should obtain safety guidance from an appropriately knowledgeable person.
Note: This symbol mark is for EU countries only. This symbol mark is according to the directive 2006/66/EC Article 20 Information for end-users and Annex II. This symbol means that batteries and accumulators, at their end-of-life, should be disposed of separately from your household waste.

v Mechanism
vMechanism
The machine carries out the processes of mastermaking and printing. Mastermaking In the mastermaking process, the old master on the drum is removed while the thermal head creates the scanned image on the new master and transfers it onto the drum.
Master roll
Thermal head
Drum unit
Printing In the printing process, paper separated from the stack by the paper feed roller and the paper separator unit is pressed against the drum unit by the press roller. There are small holes over only the image area of the master that is attached to the drum, and ink that seeps from these holes is transferred to the paper. The paper is then peeled from the master by the paper stripper finger. The paper is directed onto the paper ejection belt by a fan unit and discharged from the machine.

bMaster
1. Characteristics of the master
(1) Structure of the thermal master
(2) Functions and materials of the layers Coated surface Prevents the film from fusing, being damaged due to friction,being peeled, and being conveyed defectively due to electric static charge. Material: silicon fluorine mold lubricant Thermal film Holes are made by the heat of the thermal head. Material: Polyethylene terephthalate (polyester) Adhesive 1] Adheres the film to the base. 2] Does not prevent ink from seeping. 3] Increases impression endurance. Base 1] Base material for the master. Fibrous layer 2] Ink seeps the base. (3) Cross section of the master during mastermaking Holes are made on the coated surface, thermal film and adhesive, while base fiber, base material for the master, is left. A part of the film fused by the thermal head is stuck to the head or banks up.
(4) Printed image As the image consists of innumerable dots, it is taken as a continuous line through our eye. IMPORTANT : Precautions to be taken in dealing in the master. (1) Do not put a heavy thing on the box in which masters are packed. This may damage the master and may cause defective mastermaking. (2) Do not leave the master as it is after it is taken out. Foreign objects are stuck to the master and this may cause defective mastermaking. (3) Keep the master from direct sunlight, too high or low temperature and too high or low humidity. (Desirable storage temperature and humidity: 5-35 C, 20-80%) If the master curls, defective plate attachment may occur.

n Ink
nInk
1. Characteristics of ink
(1)Ink type Ink for the digital printer is an emulsion type. It has a water-in-oil type structure. Emulsion type
(2) 2 characteristics The surface active agent has 2 characteristics: hydrophilic group and lipophilic group in 1 molecule. Oil and water bond together by these 2 characteristics as shown in the figure.
(3) Temperature Ink viscosity is high at a low temperature and it is low at a high temperature. So when ink is used at a low temperature (10C or less), the amount of ink transferred to the paper is smaller and the print darkness is slightly lighter. When ink is used at a high temperature (30C or more), the amount of ink transferred to the paper is larger and the print darkness is slightly darker. IMPORTANT : Precautions to be taken in handling ink (1) Storage environment When an emulsion type ink is stored at too high or low temperature for a long time, oil and water in the ink pack may be isolated. Keep the ink from too high or low temperature (5C or less, 35C or more). Also keep the ink from direct sunlight since the temperature rises sharply in the direct sunlight. When the water content is frozen, the water content is solidified and the bond characteristics decreases. When ink is stored at a high temperature, the bond characteristics decreases due to the change of the surface conditions (surface tension, solubility). The bond characteristics also decreases due to evaporatin of the water content. (2) Precautions to be taken in handling the ink pack When the ink pack is removed from the drum unit to store, put the ink pack with its mouth up, screw the cap firmly after expelling air from the ink tube. (If air is in the ink pack, water content is generated.) 19

IMPORTANT : If paper feed length is too large: the arching dimension will be too large, and if the paper is
of a very stiff type, it will buckle up between the paper feed roller and the paper feed inlet (upper), causing a PAPER JAM error ("PAPER LEFT JAM"). If paper feed length is too small: the arching dimension will be too small, so that arching will be unable to correct skewing of the paper, and skewing and wrinkling will be liable to occur. Furthermore, the slippage that occurs when the timing roller feeds the paper through will be very large, resulting in printing position errors.

Operation Sensing of feed tray upper limit 2When the feed tray rises, the paper in it presses the paper feed roller upward, making the paper feed shaft lever (photointerrupter) rotate upwards about its fulcrum, until it no longer obstructs the sensors light beam. Restoration of the sensors light beam signals that the paper tray has reached the upper limit, and triggers stopping of the feed trays rise. Sensing of paper decrease 2As printing progresses and the paper decreases, the paper feed roller gradually descends, until it obstructs the sensors light beam. When this happens, the feed tray is raised until the light beam is restored. If the light beam is not restored within about 30 seconds of the sending of the RAISE FEED TRAY command, error E002 (elevator lock) is displayed.

When an absence of paper is detected, the message "SET PRINT PAPER" is displayed on the operation panel. 2When absence of paper is sensed, mastermaking, printing and test printing are not possible. 2If the paper runs out during printing, "SET PRINT PAPER" is displayed on the operation panel, printing is stopped, and the feed tray descends to its lower limit position. 2If the paper runs out during platemaking, operation continues until the end of the mastermaking process, then operation stops (without proceeding to the printing process), and the feed tray descends to its lower limit position.

(1) Home Position / Jam Detection Position Sensor
The home position / jam detection position sensor detects the drum home position and jam detection position. 2The drum home position is the position where the drum stops at the same time when a beep sounds after the jog switch (drum rotator switch) is kept pressing. 2The jam detection position is the timing to check paper jamming in the paper ejection section. 2Paper jamming in the paper ejection section is checked in the above timing with the jam sensor (photoreceiving) and P roll sensor.

Sequence of Operation 2When the JOG Switch (Drum Rotator Switch) Is Pressed Down In the normal state, the drum rotates (within one rotation) when the JOG switch (drum rotator switch) is kept pressed and the drum stops at the stop position, reducing the speed to the slow (before-stop) speed at the first master detachment position. When the P roll sensor is in the photopassing state (P roll ON) at the first master detachment position, the drum passes the stop position without reducing the speed.

1. Paper Jam Detection Timing Description Paper jamming is divided into two types: "PAPER RIGHT JAM" (ejection side) and "PAPER LEFT JAM"(feeder side). Paper jamming is detected under the following conditions. When paper jamming is detected, "PAPER JAM" is displayed on the error display panel on the control panel, and the machine stops printing operation. The display is cleared by removing the cause of paper jam and pressing the STOP key or by restarting printing.
2Paper jamming on the ejection side
JAM1: The bottom end of the paper is not ejected. When the jam sensor (light-emitting and light-receiving) is interrupted at the timing of jam detection position edge (photopassing \ photointerrupting) of the drum home / jam detection position sensor PS5. JAM2: The tip end of the paper is not ejected. When the JAM sensor is not interrupted at all while the P roll sensor is in the state of photopassing (pressed ON). JAM (stop): When the JAM sensor is interrupted as the master ejection box is open when the machine stops. The display is cleared when the sensor is in the state of photopassing. 2Paper jamming on the feeder side JAM3: The paper does not pass the signal lever though the paper is fed. The P roll sensor is not in the state of photopassing when the drum rotates twice after the paper feed solenoid is ordered ON. Sequence of Operation

The ink control section is in the drum unit. The ink control section is supplied with ink in the ink pack attached to the drum unit by the motor. The ink control section has an ink detection function, and is always supplied with a fixed amount of ink. Printing darkness is adjusted by changing the gap between the squeegee roller and the ink roller. Five color inks are available: black, red, blue, green and brown. Perform color printing to replace the drum unit for each color. (Press the drum rotation switch to the drum home position to replace the drum unit.) In this machine, whether there is a drum or not is detected. If the drum is not attached properly, it is taken as "DRUM NOT SET", and "DRUM NOT SET" is displayed on the control panel.

(1) Ink Detection
Description The ink amount variation in the ink control section is read by the electric capacity variation between the detection needles on the ink detection PCB Unit and the GND and the ink signal is output to the main PCB Unit. The main PCB Unit controls the motor ON and OFF by this signal. When NO INK continues while the drum rotates 20 times (the number of drum unit rotations; it varies depending on the printing speed.*) during printing, it is determined that the ink pack is empty, "EXCHANGE INK" is displayed and the machine stops printing. \See page 113

Dirt*foreign matter in transfer path Incorrect paper feed path pressure Worn paper feed roller Paper separator unit gap
Remove any dirt or foreign matter. Explain to users how to select correct pressure for paper. Replace paper feed roller. Perform paper separator unit gap adjustment.
Separation pressure
Paper slant is large, causing creases. During printing, paper feed errors often occur immediately before or after paper tray rises. If amount is too short, paper slant cannot be corrected, printing position may not be uniform, or paper may not be fed. If amount is too long, loop becomes too large, causing paper to buckle up between paper feed roller and timing roller, resulting in feed error. Clutch slippage will reduce paper feed amount. If clutch does not disengage properly, the paper feed segment gear will not return correctly, leading to reduced feed amount. (See Paper feed amount above.) If Guide roller pressure is insufficient, paper will not be gripped properly, and timing roller will not assure constant feed amount. As a result, printing position will not be uniform. In the worst case, no paper will reach drum. If there is a gap between Guide roller and the timing roller, paper slant cannot be corrected. If the timing roller clutch slips, feed amount will not be constant. As a result, printing position will not be uniform. In the worst case, no paper will reach drum. If the timing roller clutch does not disengage properly, the paper feed segment gear will not return correctly, leading to reduced and unstable feed amount. As a result, printing position will not be uniform. In the worst case, no paper will reach drum. Paper may be damaged in the part of leading edge that touches the signal lever. In the worst case, paper may stick to the signal lever.
Timing roller

zTroubleshooting Guide
Image of document
Adjust leading edge margin to about 10 mm. (Too long margin will cause adverse results.) Explain causes to users. If possible, have user change position for set-solid. Explain causes to users. Have user desist from excessive use of A/C or heating. If possible, have user take anti-dryness measures including humidifiers. Perform printing position sensors adjustment.
Static electricity
If leading edge margin is not correct, scrunch-up of paper will likely result. IMPORTANT: Scrunch-up of paper may also result if the margin is too long. If Guide roller pressure is insufficient, paper will not be gripped properly, causing less feed amount determined by timing roller, or disappearance of leading edge margin. This results in the paper scrunchup. Any slippage of the timing roller clutch will reduce feed amount and eliminate leading edge margin. This results in the paper scrunch-up. If the timing roller clutch does not disengage properly, the timing roller segment gear will not return correctly, causing reduction of feed amount or disappearance of leading edge margin. As a result, paper will scrunch up. If timing is too low, or the gap between drum and the leading edge of paper is too large, paper stripper finger will not enter into the gap, causing the paper scrunch-up. If sufficient air is not delivered from the tip of the paper stripper finger, it will not lift the leading edge of paper off drum. Scrunch-up of paper will result.
Air
Check if the hole in the fingers tip is blocked by foreign matter. Check pipes for kinks or disconnections. Check valves and O-rings on the air pump. If the belt is broken or stretched, replace it.
If the speed of the paper ejection belt, if cannot eject the paper onto the paper receiving plate with sufficient force. As a result, there will be paper jams in the vicinity of the discharge port. (Sometimes the trailing edge of the paper gets caught in the jamming sensor and a paper jamming error is displayed.) If the suction force of the fan drops, it will not be able to blow the paper (which has risen clear of the ejection belt) onto the paper receiving plate with be paper jams in the vicinity of the discharge port. (Sometimes the trailing edge of the paper gets caught in the jamming sensor and a paper jamming error is displayed.) Too much ink transferred to paper will likely cause scrunch-up of paper.
Clean the fan. If it still does not work properly, replace it.
Ink
Perform ink volume adjustment of drum. Explain user that ink transfer volume increases immediately after paper scrunchup, and advise user to restart printing at standard speed, then.

x Overview
x Overview
The Duprinter's HELP modes can be broadly classified into the following types:
main PCB unit is replaced and after initialization setting has been implemented (using HELP mode H-27).
These modes permit the running of function checks on: individual motors, given series of operations, and electrical circuits. When these modes are used to check motor functioning, the motor being checked is run by itself, but interlocks are suspended. When such checks are run, take care not to put hands or fingers in motor-related moving parts that could start up unexpectedly.
Failure to heed the above could result in crushed or otherwise injured hands or fingers.
