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 possi-

ble 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 precau-

tions as necessary. When performing repair or service work not covered by this man-

ual, you should obtain safety guidance from an appropriately knowledgeable person.

chap.1 v Mechanism

The machine carries out the processes of “mastermaking” and “printing.”

Mastermaking

In the “mastermaking” process, the old master on the drum is removed while thethermal head creates the scanned image on the new master and transfers it onto thedrum.

Printing

In the “printing” process, paper separated from the stack by the paper feed roller andthe paper separator unit is pressed against the drum unit by the press roller. There aresmall holes over only the image area of the master that is attached to the drum, and inkthat seeps from these holes is transferred to the paper. The paper is then peeled fromthe master by the paper stripper finger. The paper is directed onto the paper ejectionbelt by a fan unit and discharged from the machine.

chap.1 b Master

1. Characteristics of the master(1) Structure of the thermal master

(2) Functions and materials of the layersCoated 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 layer2] Ink seeps the base.

(3) Cross section of the master during mastermakingHoles are made on the coated surface, thermal film and adhesive, while base fiber, base materialfor the master, is left.A part of the film fused by the thermal head is stuck to the head or banks up.

(4) Printed imageAs 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.

chap.1 n Ink

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 (5°C or less, 35°C 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 evaporatinof 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.)

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 (10°C or less), the amount of ink transferred to the paper is smaller and the printdarkness is slightly lighter.When ink is used at a high temperature (30°C or more), the amount of ink transferred to the paper is larger and the print darkness is slightly darker.

xMastermaking / Master Feed / Ejection Section

1. Description

Make the master clamp of the drum unit clamp the master top end, performing mastermaking on the masterwith the thermal head. (In this machine, the master on the drum is ejected at the same time when platemaking is performed.)The master is conveyed to the drum unit via the platen roller and sponge roller by driving of the steppingmotor, while it is being processed in the head section. Sponge roller is driven through the master feedingclutch (electromagnetic clutch), and controls the amount of master conveyed to the master clamp section ofthe drum unit with the master feeding clutch ON / OFF.The end-mark sensor1 starts to detect when the end mark (black) section printed on the end of the roll masteris conveyed. The indicator lights for "roll-master end" are lit on the control panel. The endmark sensor also detects whether the master is conveyed properly through the sensor.

The end marks are located at a fixed distance relative to the master; as the master is being fed, the end-marksensor1 senses master condition and the end marks by means of intensity of reflected light.

The larger the reflection light amount is, the smaller the output voltage is. The smaller the light amount is,the larger the output voltage is.The value is checked with the HELP 13.

qMaster Setting Error DetectionOperationIn mastermaking, the end-mark sensor1 uses amount of reflected light to detect presence or absence of a master on the transfer path. Then the following displays and operations are performed:

• When a master setting error is detected, "MASTER SET MISS" is displayed and printing is not processed.

• "MASTER SET MISS" is only cleared by resetting master rightly again.(It is not cleared by turning the power off.)

• Printing is not performed but mastermaking is only performed when the display is cleared after "MASTERSET MISS" is displayed. (Because the master is not attached to the drum.)

Timing(1) While mastermaking is being processed, the reflection light amount does not turn to be in a white level.(2) When mastermaking process is finished (before printing process), the reflection light amount is in a white

level.

wMaster End DetectionOperationThe end mark is printed on the area about 1 m from the end of the master.The end-mark sensor1 detects the changed value of the reflection light amount of the end mark during

Cutter Unit

Completed, the stepping motor for mastermaking and the drum stops temporarily, the cutter motor (MS) isturned on to drive the cutter and the master is cut.The home position for the cutter motor is at the cutter limit SW on the operation side (MS1). When the cuttermoves to turn on the cutter limit SW on the rear side (MS2), the cutter motor stops and then reversely rotatesto return to the home position.(The cutter motor can rotate normally and/or reversely.)

The cutter motor is at the home position when the cutter limit SW (MS1) is closed and the cutter limit SW(MS2) is opened. When cutting the master, the cutter motor rotates normally (CW) and moves from the operation side to the rear side. When the cutter limit SW (MS1) is opened and the cutter limit SW (MS2) isclosed after cutting is completed, the cutter motor stops and then rotates reversely (CCW) , and moves fromthe rear side to the operation side.

2. Rotation Control of the Roll-up MotorIf the roll-up motor is kept rotating when the master tip end is pulled to the ejection box in the masterdetachment process, the drum is actuated by the master and the stop position slips. To prevent this, the roll-up motor is stopped when the master is detected by the master ejection sensor. (If the master is notdetected by the master ejection sensor, the Roll-up motor is stopped by the timer.)

(1) Master Ejection Sensor

DescriptionPhoto-emission from the master ejection sensor isreceived on the master ejection sensor, and thesensor detects with the photo strength whether themaster is pulled to the master ejection box. Photo-receiving amount is checked with theHELP5.

c Paper Feed Sectionchap.2

1. DescriptionFeeding of the paper is performed by the paper separator (employing the center separation method) and paperfeed roller (there is no corner finger). Elevation of the feed tray is powered by the elevator motor. Paper fed bythe paper separator and paper feed roller is fed further by the timing roller and guide roller to the pointwhere its leading edge is sandwiched between the drum and the press roller. Then the pression of the timingroller and guide roller is released (by moving the guide roller upward several mm), so that the paper is fedthrough at a speed equal to the circumferential speed of the drum and press roller. The press roller sensorsenses the paper feed condition; if a feed error occurs, the message “PAPER LEFT JAM” is displayed. Fordetails, see “1.Paper Jam Detection Timing” in chapter 2 (n Paper ejection section). \See page 107

When the main motor turns, the paper feed cam rotates, causing the paper feed segment and timing segmentto execute the reciprocating motion shown below, which turns the pinion gear.

2. Operation

(1) Rotation of the Paper Feed Roller andTiming Roller

23S0223

84


The paper feed roller is driven by the main motor via the timing belt and the paper feed clutch. The rotationaltiming depends on the ON/OFF state of the paper feed clutch and is controlled by the program.

After the Press roller is pressed to the drum, the printing paper is gripped firmly with the drum and Pressroller, the Guide roller is released from the Timing roller. This is called "escaped". Escape timing is within aperiod when the printing paper is conveyed about 10 mm after it is gripped with the drum and Press roller.

(4) Escape the Guide Roller

¡When the timing is too late, the printing paper is gripped at two places too long. Thusmaster elongation and slippage occur.

¡On the contrary, when the timing is too early, the printing paper is not gripped at all, and itis not well settled. Thus creasing of paper and dispersion of the printing position occurs.

The “paper feed length” is the length by which the paper feed roller feeds out the print paper. When the paperfeed roller feeds out the print paper, the guide roller is pressed against the timing roller and does not rotate;as a result, the paper arches up between the paper separator and the timing roller, since the distance betweenthese two items is only 80mm, while the length by which the paper is fed out from the paper feed roller is95mm. This arching has the effect of correcting any skewing of the paper (as the leading edge is held firmbetween the guide and timing rollers). It also has the effect of lessening the load on the timing roller when itfeeds the paper through, thus minimizing slippage.For feed amount, the leading edge of the paper is detected by the paper feed length sensor and paper feed iscontrolled by program( HELP mode H-66,67 ). HELP mode H-66,67 \ see p.284-285

¡If paper feed length is too large: the arching dimension will be too large, and if the paper isof 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 archingwill be unable to correct skewing of the paper, and skewing and wrinkling will be liable tooccur. Furthermore, the slippage that occurs when the timing roller feeds the paperthrough will be very large, resulting in printing position errors.

(2) Signal Lever

The signal lever is positioned at the back of the Guide roller / Timing roller. Whether the paper is fed by theTiming roller is detected mechanically.

The pinch lever is attached to the other end of the shaft to which the signal lever is attached. As the signallever is jumped by the paper, the pinch lever also jumps. Accordingly the Press roller is out of control andrises. The above operation keeps the drum from dirts as the Press roller is in contact with the drum when thepaper is not fed. As the Press roller sensor detects rising of the Press roller, Whether the paper is fed from thepaper feed section to the printing section normally is detected indirectly.

(3) Feed Tray (Elevator) Upper Limit Sensor

Description

Circuits

Operation

The feed tray (elevator) upper limit sensor senses decrease of the paper pile, and the upper limit position ofthe feed tray. It does so by detecting the up/down motion of the paper feed shaft.

Sensing of feed tray upper limit2When 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 sensor’s lightbeam. Restoration of the sensor’s light beam signals that the paper tray has reached the upper limit, andtriggers stopping of the feed tray’s rise.

Sensing of paper decrease2As printing progresses and the paper decreases, the paper feed roller gradually descends, until it obstructs

the sensor’s 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 TRAYcommand, error E002 (elevator lock) is displayed.

Operation

Senses presence/absence of paper in the feed tray. When the paper in the tray runs out, the message "SETPRINT PAPER" is displayed and printing stops.

When there is no paper, the lever moves away and the sensor opens. When paper is placed inside, the leverpresses the actuator and the sensor closes. When an absence of paper is detected, the message "SET PRINTPAPER" 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 lowerlimit position.

Causes Symptoms Countermeasure

Printing paper not suit-able

• If paper is too thick, it won’t be likely fed. If too thin, dou-ble sheets may be fed.

• Paper not clearly cut: 2 sheets still adhere to eachother.

• Much paper scraps may deteriorate the paper feedroller and separator performance.

Explain causes to user. Have userchange to the paper conforming tospecifications.

Dirt*foreign matter intransfer path

• Paper gets stuck in transfer path, causing creasing andtearing.

Remove any dirt or foreign matter.

Incorrect paper feed pathpressure

• If pressure on paper is insufficient, paper will not be fed.• If pressure on paper is excessive, double sheets will be

fed.

Explain to users how to select cor-rect pressure for paper.

Worn paper feed roller • Paper may not be fed. Replace paper feed roller.

Paper separator unit gap • If gap is too large, separator unit will rattle in direction ofpaper transfer path, causing double sheets to be fed.

• If gap is too small, paper separator unit cannot followangle change due to paper feed shaft up-down move-ment, which may cause double-sheet or slanted feed,and creasing.

Perform paper separator unit gapadjustment.

Paper separator unit • Wear, or adhesion of paper scraps causes deteriorationin separating performance, resulting in double-sheetfeed.

Clean separating surfaces. If anytrouble exists, replace. Perform sep-arator unit gap adjustment on newunit.

Separation pressure • If pressure is very low, no paper will be fed. Perform separation pressure adjust-ment.

Paper tray upper positionlimit

• Paper slant is large, causing creases.• During printing, paper feed errors often occur immedi-

ately before or after paper tray rises.

Perform paper feed tray upper limitsensor adjustment.

Paper feed amount • If amount is too short, paper slant cannot be corrected,printing position may not be uniform, or paper may notbe fed.

• If amount is too long, loop becomes too large, causingpaper to buckle up between paper feed roller and timingroller, resulting in feed error.

Perform paper feed amount adjust-ment.

Paper feed clutch • Clutch slippage will reduce paper feed amount.• If clutch does not disengage properly, the paper feed

segment gear will not return correctly, leading toreduced feed amount.

(See “Paper feed amount” above.)

Replace paper feed cluch.

Guide roller pressure &timing

• If Guide roller pressure is insufficient, paper will not begripped properly, and timing roller will not assure con-stant feed amount. As a result, printing position will notbe uniform. In the worst case, no paper will reach drum.

• If there is a gap between Guide roller and the timingroller, paper slant cannot be corrected.

Perform escape amount adjustmentand escape timing adjustment.

Timing roller • If the timing roller clutch slips, feed amount will not beconstant. As a result, printing position will not be uni-form. 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 aresult, printing position will not be uniform. In the worstcase, no paper will reach drum.

Clean timing roller clutch . Replaceif necessary.

Incorrect signal leveroperation

• Paper may be damaged in the part of leading edge thattouches the signal lever. In the worst case, paper maystick to the signal lever.

Clean bearing unit. Check that sig-nal lever moves smoothly.

Causes Symptoms Countermeasure

Printing paper not suit-able

• If paper is too thin, it will stick to drum and scrunch up.• If grain of paper is sideways relative to transfer direction, paper will

crunch up, or get jammed on the paper receiving plate.• If paper curl upward, it will likely scrunch up. If curl downward, it will

likely get jammed on the paper receiving plate.

Explain causes to users. Have userchange to paper conforming tospecifications.

Image of document • If set-solid exists near leading edge of paper, paper will likely scrunchup.

• If set-solid is blasted to one side of paper, paper will not be ejected ina straight line. As a result, ejected paper will be disorderly piled andlikely jam on the paper receiving plate.

• Adjust leading edge margin toabout 10 mm. (Too long marginwill cause adverse results.)

• Explain causes to users. If possi-ble, have user change position forset-solid.

Static electricity • If ambient air is dry, static electricity may cause disordered piles orscrunch-up of paper.

• Explain causes to users. Have user desistfrom excessive use of A/C or heating.

• If possible, have user take anti-drynessmeasures including humidifiers.

Leading edge margin • If leading edge margin is not correct, scrunch-up of paper will likelyresult.

Scrunch-up of paper may also result if the margin is too long.IMPORTANT:

• Perform printing position sensorsadjustment.

Guide roller pressure &timing

• If Guide roller pressure is insufficient, paper will not be gripped proper-ly, causing less feed amount determined by timing roller, or disap-pearance of leading edge margin. This results in the paper scrunch-up.

Perform escape amount and escapetiming adjustments.

Timing roller clutch • Any slippage of the timing roller clutch will reduce feed amount andeliminate leading edge margin. This results in the paper scrunch-up.

• If the timing roller clutch does not disengage properly, the timing rollersegment gear will not return correctly, causing reduction of feedamount or disappearance of leading edge margin. As a result, paperwill scrunch up.

Clean timing roller clutch. Repair ifnecessary.

Paper stripper finger • If timing is too low, or the gap between drum and the leading edge ofpaper is too large, paper stripper finger will not enter into the gap,causing the paper scrunch-up.

Perform paper stripper finger adjust-ment.

Air • 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 paperwill result.

• Check if the hole in the fingers tipis blocked by foreign matter.

• Check pipes for kinks or discon-nections.

• Check valves and O-rings on theair pump.

Paper ejection belt • If the speed of the paper ejection belt, if cannot eject the paper ontothe paper receiving plate with sufficient force.As a result, there will be paper jams in the vicinity of the dischargeport. (Sometimes the trailing edge of the paper gets caught in the jam-ming sensor and a paper jamming error is displayed.)

If the belt is broken or stretched,replace it.

Paper ejection fan unit • If the suction force of the fan drops, it will not be able to blow thepaper (which has risen clear of the ejection belt) onto the paperreceiving plate with be paper jams in the vicinity of the discharge port.(Sometimes the trailing edge of the paper gets caught in the jammingsensor and a paper jamming error is displayed.)

Clean the fan. If it still does not workproperly, replace it.

Ink • Too much ink transferred to paper will likely cause scrunch-up ofpaper.

• Perform ink volume adjustment of drum.• Explain user that ink transfer volume

increases immediately after paper scrunch-up, and advise user to restart printing atstandard speed, then.

x Overview

¡Failure to heed the above could resultin crushed or otherwise injuredhands or fingers.

The Duprinter's HELP modes can be broadly classified into thefollowing types:

◆ Modes for ROM version displayThese modes display the version numbers of the main PCB unit'sROM (U19), the I/F PCB unit's ROM,the Panel PCB unit's ROM,

◆ Modes for adjustment / specification settingThese modes set the functioning of variable resistors and switchesby using the main PCB unit's EEPROM(U23) to memorize settingsmade on the operation panel. All of these adjustments and settingsare made at the factory prior to shipment of each Duprinter.

¡New adjustments and appropriate settings must be made after themain PCB unit is replaced and after initialization setting hasbeen implemented (using HELP mode H-27).

◆ Modes for function checksThese modes permit the running of function checks on:individual motors, given series of operations, and electricalcircuits.When these modes are used to check motor functioning, themotor being checked is run by itself, but interlocks aresuspended. When such checks are run, take care not to puthands or fingers in motor-related moving parts that could startup unexpectedly.

IMPORTANT

◆ Modes for sensor and switch displaysThese modes provide displays of the conditions of sensors andswitches.

◆ Modes for total count displaysThese modes provide displays of the counts of the total number ofmasters made and sheets printed by the Duprinter since it wasmanufactured. They also permit resetting of the total count valuesdisplayed in the user mode.
