1. Size B4 printing (DP-23S)

The DP-23S has size B4 (248X355mm) printing area.

The DP-21L has size A4 (210X355mm) printing area.

The DP-21S has size A4 (204X288mm) printing area.

2. High-speed platemaking

With the DP-23S/21S/21L, it takes 25 seconds*1 to

print the first sheet of paper.

*1: Time required to print the first sheet of paper after

the platemaking key is pressed.

3. High print quality

A new, originally-developed superfine thermal head

gives beautifully accurate reproductions of fine print

and halftone photographs.

Its resolution is 300dpi in the main scanning direction and 600dpi in the sub scanning direction.

4. Align paper

Adjusting the eject enables both thin and thick

sheets of paper to be aligned neatly.

5. High-performance lamp

A long-life, high-brightness xenon arc lamp is used

to illuminate the documents. Since the lamp's

intensity is not affected by temperature variation*2,

printing quality at low temperatures is greatlyenhanced*3.

*2: The lamp is filled with xenon gas, which means that it

does not require heat to vaporize mercury, as a

fluorescent lamp does, and therefore its intensity does

not vary with temperature.

*3: Increased viscosity of the ink at low temperatures

results in fa inter print ing than at normal

temperatures.

6. Full range of necessary functions

qDocuments are easily enlarged or reduced.

In addition to same-size printing, there are threeautomatic settings for both enlargement and

reduction. The margin function (94% reduction)

can be used with any setting.

chap.1 v Mechanism

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

Platemaking

In the “platemaking” 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.

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.

chap.1 b Master

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 lubricantThermal 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 platemaking

Holes 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 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 platemaking.

(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 platemaking.

(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 print

darkness 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.

zScanner Section

1. Description

The machine contains a scanner of the document moving type which scans images while the document isfed.The document is illuminated with the lamps while being transferred, and the reflection in proportion to

the document image darkness is imaged on the CCDs through the mirror and lens. Then the image is

resoluted into picture elements and converted photoelectrically into the level of electricity simultaneously.

The document is fed and carried by a single stepping motor. Two clutches (A and B) are used to engage or

disengage the ADF feed roller and the feed roller.The clutch is turned on only for feeding paper to engage the

scanner stepping motor with the driving system for the ADF feed roller. After the document reaches the feed

roller, clutch A is turned off and clutch B is turned on.The roller follows the movement of the document (fed by

the ejection roller).

(2) Basic Operation for Feeding Paper to Scanner

(1) Paper feed 1

When the document is placed on the document

receiving tray, the document sensor is

photointerrupted and detects the presence of the

document. Pressing the PLATEMAKING key

turns on the scanner stepping motor and clutch

A, feeding the document.

(2) Positioning

Clutch A and the stepping motor are turned off

when the document is fed 16mm after the JAM

sensor is photointerrupted. This prevents the

position of the documents from deviating, which

is caused by meandering during paper feeding. If

the front end of the document does not reach the

document sensor within 5 seconds after the JAM

sensor is photointerrupted, DOCUMENT JAM

will be displayed.

(3) Paper feed 2

The scanner stepping motor and clutch B are

turned on again and the document is fed.

(4) Reading the document

After the front end of the document is detected

at the document sensor, the document is fed

several steps, and shading is performed on

approximately 2mm of the front end of thedocument.

Operation

(1) Paper feed 1 for the second document

If the document sensor is photointerrupted whenthe document has been ejected and platemaking

process is finished at the master feeding section,

it is determined that the next document exists

and the scanner stepping motor, and the clutch A

is turned on to feed the document.

(2) Positioning

When the front end of the document reaches the

document position sensor, the document position

sensor is photointerrupted and detects the front

end of the document, which turns off the scanner

stepping motor and the clutch A to hold.This

method assures stable positioning of the

document.

(3) Reading the document

After the front end of the document is detected

at the document sensor, the document is fed

several steps, and shading is performed on

approximately 2mm of the front end of the

document.

When PLATEMAKING key is

pressed, the print section

detaches the plate and then the

drum moves to the plate

attachment position to open the

master clamp, while ADF remains

held.

xPlatemaking / Master Feed / Ejection Section

Make the master clump of the drum unit clump the master top end, performing platemaking on the master

with 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 stepping

motor, while it is being processed in the head section. Sponge roller is driven through the master feeding

clutch (electromagnetic clutch), and controls the amount of master conveyed to the master clamp section of thedrum unit with the master feeding clutch ON / OFF.

The end mark sensor starts to detect when the end mark (black) section printed on the end of the roll master

is conveyed. "ROLL MASTER END" is displayed on the error display panel. The endmark sensor also detects

whether the master is conveyed properly through the sensor.

In platemaking, the end mark sensor 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:

2When a master setting error is detected, "MASTER SET MISS" is displayed and printing is not processed.

2"MASTER SET MISS" is only cleared by opening and closing the top cover.

(It is not cleared by turning the power off.)

2Printing is not performed but platemaking is only performed when the display is cleared after "MASTER

SET MISS" is displayed. (Because the master is not attached to the drum.)

Timing

(1) While platemaking is being processed, the reflection light amount does not turn to be in a white level.

(2) When platemaking process is finished (before printing process), the reflection light amount is in a white

level.

sensor detects with the photo strength whether the

master is pulled to the master ejection box.

Photo-receiving amount is checked with the

HELP5.

1. Master Ejection Error Detection

Operation

While one platemaking is being processed, the difference of photo-receiving amount is less than 8 by checking

with the HELP5, which is determined as an master ejection error. The following display and operation are

shown.

2"MAST. EJECT ERROR" is displayed on the error display panel and printing is not processed.

2"MAST. EJECT ERROR" is cleared with the ALL CLEAR key , STOP key or by performing

platemaking / printing.

2 A plate ejection error is not detected for one platemaking soon after a plate ejection error or master setting

error is detected.

The mode is detected under the following conditions

2A mode

When the B mode sensor (PS4) is photointerrupted, the A / C mode sensor (PS3) detects the edge of

photointerrupting f photopasing.

*With the power ON, the A mode is determined when the B mode sensor is in the photointerrupting state

and the A/C mode sensor is in the photopassing state. If not in the A mode with the power ON, the

master clump opening / closing lever rotates to the B mode and stops. When the lever stops at the

B mode, the drum rotates with the drum rotation switch and returns to the A mode at the stop position.

2B mode

When the A/C mode sensor is photointerrupted, the B mode sensor detects the edge of photointerrupting /

/photopassing or photopassing - photointerrupting.

2C mode

When the B mode sensor is photopassing, the A/C mode sensor detects the edge of photointerrupting f

c Paper Feed Sectionchap.2

1. DescriptionFeeding of the paper is performed by the paper separator (employing the center separation method) and paper

feed roller (there is no corner finger). Elevation of the feed tray is powered by the elevator motor. Paper fed by

the paper separator and paper feed roller is fed further by the timing roller and guide roller to the point

where its leading edge is sandwiched between the drum and the press roller. Then the pression of the timing

roller and guide roller is released (by moving the guide roller upward several mm), so that the paper is fed

through at a speed equal to the circumferential speed of the drum and press roller. The press roller sensor

senses the paper feed condition; if a feed error occurs, the message “PAPER LEFT JAM” is displayed. For

details, see “1.Paper Jam Detection Timing” in chapter 2 (n Paper ejection section). \See page 109

When the main motor turns, the paper feed cam rotates, causing the paper feed segment and timing segment

to execute the reciprocating motion shown below, which turns the pinion gear.

2. Operation

(1) Rotation of the Paper Feed Roller and

Timing Roller

23S0223




The paper feed roller is driven by the main motor via the timing belt and the paper feed clutch. The rotational

timing depends on the ON/OFF state of the paper feed clutch and is controlled by the program.

(2) Paper Feed Roller Drive

reciprocating motion of the timing roller segment is transmitted to the pinion gear, and the spring clutch

works to rotate the Timing roller in the direction of conveyance.

After the Press roller is pressed to the drum, the printing paper is gripped firmly with the drum and Press

roller, the Guide roller is released from the Timing roller. This is called "escaped". Escape timing is within a

period when the printing paper is conveyed about 10 mm after it is gripped with the drum and Press roller.


¡When the timing is too late, the printing paper is gripped at two places too long. Thus

master elongation and slippage occur.

¡On the contrary, when the timing is too early, the printing paper is not gripped at all, and it

is 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 paper

feed 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 between

these two items is only 80mm, while the length by which the paper is fed out from the paper feed roller is

95mm. This arching has the effect of correcting any skewing of the paper (as the leading edge is held firm

between the guide and timing rollers). It also has the effect of lessening the load on the timing roller when it

feeds the paper through, thus minimizing slippage.

For feed amount, the leading edge of the paper is detected by the loop sensor and paper feed is controlled by

program.

¡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 tooccur. Furthermore, the slippage that occurs when the timing roller feeds the paper

through 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 the

Timing 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 signal

lever is jumped by the paper, the pinch lever also jumps. Accordingly the Press roller is out of control and

rises. The above operation keeps the drum from dirts as the Press roller is in contact with the drum when the

paper is not fed. As the Press roller sensor detects rising of the Press roller, Whether the paper is fed from the

paper 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 of

the feed tray. It does so by detecting the up/down motion of the paper feed shaft.

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 sensor’s light

beam. Restoration of the sensor’s light beam signals that the paper tray has reached the upper limit, and

triggers stopping of the feed tray’s rise.

Sensing of paper decrease

2 As 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 TRAY

command, error E002 (elevator lock) is displayed.

Description

Circuits

Operation

This is a micro switch (SM6) that senses the lower limit position of the feed tray.

When the feed tray rises, the bracket disengages from the switch and the switch closes. When the feed tray

descends to its lower limit position, the bracket engages the switch’s actuator, opening the switch.

If the switch does not open within about 30 seconds of the sending of the LOWER FEED TRAY command, error

E002 (elevator lock) is displayed.

When there is no paper, the lever moves away and the sensor opens. When paper is placed inside, the lever

presses the actuator and the sensor closes. When an absence of paper is detected, the message "SET PRINT

PAPER" is displayed on the operation panel.

2When absence of paper is sensed, platemaking, 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 platemaking process,

then operation stops (without proceeding to the printing process), and the feed tray descends to its lower

limit position.

m Drum Sectionchap.2

mDrum Section

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.

Description

The ink amount variation in the ink control section is read by the electric capacity variation between thedetection 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, "CHANGE

INK" is displayed and the machine stops printing.

(1) Ink Detection


\See page 115






2. "CHANGE INK" Display Timing

When HIGH (5V) is output by detecting ink while the drum continues to rotate 20 times (the number of

rotations varies depending on the printing speed.*) during printing, it is detected that the ink pack is empty,

"CHANGE INK" is displayed on the error display, and printing stops. At the same time the power for the ink

motor is turned off.

*The drum rotates until "CHANGE INK" is displayed after HIGH is output from the ink detection PCB unit

during printing. The number of drum rotations varies depending on the printing speed as follows:-

Description

The drum switch detects whether the drum is installed to the machine.

When it is detected that there is no drum installed, "DRUM NOT SET" is displayed on the error display panel

on the control panel the machine stops operation. When no drum is detected during operation, all the

operations stops emergently.

Operation

When the drum is attached to the main body, the cam unit covers the pin and is locked firmly. The difference

of the cam unit prevents the cam unit from being loosened due to the machine vibration.

When the pin is at the bottom of the cam unit difference, the drum SW is open as shown in the figure. When

the pin is over the cam unit difference, the drum SW is closed.

Description

The front cover switch detects opening and closing of the front cover. "FRONT COVER OPEN" is displayed on

the error display panel on the control panel, when it is detected that the front cover is open. When the front

cover is open, platemaking and printing is not performed. When the front cover open is detected during

printing, the machine stops immediately. (When the front cover open is detected during platemaking, the

machine stops before processing printing.)

Operation

When the front cover is closed, the lever presses the switch and is closed. When the front cover is open, the

lever is apart from the switch and is open.

, Optionchap.2

When attaching the TAPE

CLUSTER, set the mode to the

HELP mode 28 with TAPE

CLUSTER.

(For further details, refer to the list

of the HELP modes. If it is not set,

the TAPE CLUSTER does not work.)

IMPORTANT :

2When the number of sets is input without a TAPE

CLUSTER (optional), the following is operated.

Printing stops at the timing of feeding tape, Press

the PRINT key again to start printing.

(Manual clustering)

Description

A certain length of tape is fed and cut from the

TAPE CLUSTER to finish printing the number of

sets in the cluster printing operation. The operation

is continued to process the number of sets.

*Printing does not stop when the tape runs out

during printing.

The number of sheets for 1 set to be processed is

1 - 9999 sheets. The number of sets for

1 classification to be processed is 1 - 99 sets.

Operation

1) The TAPE CLUSTER starts to feed the tape from the last 10 sheets for the set. A fixed length of the tape is

fed and is cut after completing printing the set amount.

This operation is repeated until the last set is processed.

The fed amount of tape is different between the large and small classifications. When all the sets for 1 clas-

sification are processed, the fed amount of tape is longer (large classification). When all the sheets for 1 set

are processed, the fed amount of tape is shorter (small classification).

Fed amount of tape for small classification: about 250mm (±15%)

Fed amount of tape for large classification: about 370mm (±15%)

2) When the number of sheets for the set is less then 10 sheets, the tape is fed at the same time when printing

starts. When the number of sheets is printed before a fixed amount of tape is fed, printing for the next set

is discontinued until the tape is fed. (Paper feeding stops. The drum rotates at a low speed.)

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 each

other.

• Much paper scraps may deteriorate the paper feed

roller and separator performance.

Explain causes to user. Have user

change to the paper conforming to

specifications.

Dirt / foreign matter in

transfer path

• Paper gets stuck in transfer path, causing creasing and

tearing.

Remove any dirt or foreign matter.

Incorrect paper feed path

pressure

• 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 of

paper transfer path, causing double sheets to be fed.

• If gap is too small, paper separator unit cannot follow

angle change due to paper feed shaft up-down move-

ment, which may cause double-sheet or slanted feed,

and creasing.

Perform paper separator unit gap

adjustment.

Paper separator unit • Wear, or adhesion of paper scraps causes deterioration

in separating performance, resulting in double-sheet

feed.

Clean separating surfaces. If any

trouble exists, replace. Perform sep-

arator unit gap adjustment on new

unit.

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

ment.

Paper tray upper position

limit

• 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 limit

sensor adjustment.

Paper feed amount • 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.

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 to

reduced feed amount.

(See “Paper feed amount” above.)

Replace paper feed cluch.

Guide roller pressure &

timing

• If Guide roller pressure is insufficient, paper will not be

gripped properly, and timing roller will not assure con-

stant 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.

Perform escape amount adjustment

and escape timing adjustment.

Timing roller • If the timing roller clutch slips, feed amount will not be

constant. 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 a

result, printing position will not be uniform. In the worst

case, no paper will reach drum.

Clean timing roller clutch . Replace

if necessary.

Incorrect signal lever

operation

• 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.

Clean bearing unit. Check that signal

lever moves smoothly.

\ see page 174




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 user

change to paper conforming to

specifications.

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

up.

• If set-solid is blasted to one side of paper, paper will not be ejected in

a straight line. As a result, ejected paper will be disorderly piled and

likely jam on the paper receiving plate.

• Adjust leading edge margin to

about 10 mm. (Too long margin

will cause adverse results.)

• Explain causes to users. If possi-

ble, have user change position for

set-solid.

Static electricity • If ambient air is dry, static electricity may cause disordered piles or

scrunch-up of paper.

• 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.

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

result.

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

IMPORTANT:

Perform printing position sensors

adjustment.

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 escape

timing adjustments.

Timing roller clutch • 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, paperwill scrunch up.

Clean timing roller clutch. Repair if

necessary.

Paper stripper finger • 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.

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 paper

will 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 onto

the 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 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.)

Clean the fan. If it still does not work

properly, replace it.

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

paper.

• Perform ink volume adjustment of drum.

• Explain user that ink transfer volume

increases immediately after paper scrunch-

up, and advise user to restart printing at

standard speed, then.
