• This takes you to the Load/Unload substrate screen.

Dimatix Materials Printer User Manual

FUJIFILM Dimatix, Inc. Confidential Information Page 19 of 93 DUM00001 Rev.09 Ver.1.3 09/06/06

Load/Unload Substrate

• On this screen you control the platen temperature and vacuum. You also must

enter the thickness of the substrate you are going to use. To start, use the

enclosed piece of glossy ink jet paper to run the test pattern. This paper is about

250 micrometers thick. Enter 250 (µm) in the box either by using the up or down

arrows on the box or placing the cursor in the box and typing in the number. The

system automatically adjusts the height of the cartridge to about 1.0 mm above the

substrate. Be sure that you enter the correct thickness. Entering a number that

is smaller than the actual thickness may cause the carriage to crash into or drag

across the substrate.

• Open the lid and place the substrate on the platen. Register it to the marks in the

back left corner of the platen which is a general substrate registration position. This

is important to note since it will be the approximate location from which the

patterns to be jetted will be referenced initially.

Dimatix Materials Printer User Manual

FUJIFILM Dimatix, Inc. Confidential Information Page 20 of 93 DUM00001 Rev.09 Ver.1.3 09/06/06

• After placing the substrate on the platen, turn on the platen vacuum by selecting

the Vacuum On button. If your substrate is not very flat, stiff, or smaller than the

platen you may need to cover some of the open vacuum holes with some mylar,

adhesive tape, or other material to direct more vacuum to your substrate.

• If you want to heat the platen, you can enter the temperature in the box by typing

or using the arrows. The system will not print until the platen reaches the desired

temperature. This may take up to 20 minutes for a setting of 60°C. By clicking on

the down arrow on the box you will get to a line in the box which represents a

setting of “no- temperature.” The platen will then run at ambient temperature.

• You are now ready to go to the next step Print Set-Up by clicking the Next button.

Print Set-Up

• Now you are finally ready to start jetting. The Pattern has been selected, the

Substrate Settings have been entered, and the Cartridge Settings have been

entered.

Dimatix Materials Printer User Manual

FUJIFILM Dimatix, Inc. Confidential Information Page 21 of 93 DUM00001 Rev.09 Ver.1.3 09/06/06

• Click on the Print button and the Print Preview window will open. This window

shows where the print origin is on the platen, where the image to be printed is and

the number of nozzles used to print.

• Click on the Print button and the pattern will be printed. Your DMP will jet the test

pattern.

Advanced Uses

Now that you have successfully been through a sequence to make a print, you can learn

more details that you may need to jet your fluid.

Cartridge Settings

In the start up procedure we showed how to select a file with a specific Cartridge Setting

that had been predetermined for the test fluid by FUJIFILM Dimatix. Now we will get into

the details of the settings and the editor screens.

Dimatix Materials Printer User Manual

FUJIFILM Dimatix, Inc. Confidential Information Page 22 of 93 DUM00001 Rev.09 Ver.1.3 09/06/06

You can view Advanced Cartridge settings using the Tools menu Enable Advanced

Features. Additional parameters are added to the cartridge settings:

By clicking on the Edit button on the Cartridge Settings box, the following screen comes

up.

On the above window you can select a previously created waveform in the File list. You

can adjust the voltage to each jet nozzle individually by typing a number in the individual

nozzle box or by clicking on the up or down arrow in the nozzle box. You may want to do

this to adjust drop velocities of individual nozzles, since velocity is a function of voltage.

You can also change all of them simultaneously with the Adjust All arrows. (See

Wavefrom Editor for effects of voltage on jetting). The Increment number is the amount

the voltage will change with one click on the up or down arrow buttons.

Note: Once you have established the settings for a particular fluid, you may have to

adjust the voltages for a new cartridge to match the drop velocity of a previous cartridge.

See Drop Watcher for instructions on setting drop velocity.

Note: Tickle control can only be accessed by opening the cartridge settings of the print

setup screen in the DMP main program. Opening the cartridge setting via the Drop

Watcher will not allow you to change tickle control as it will be displayed in gray.

If you click on the next tab on the window Cartridge, the following screen comes up.

This screen allows you to set the temperature of the cartridge. This is usually used when

the fluid is too viscous to jet and you need to lower the viscosity by raising the

temperature to get the desired jetting performance.

Also on this window is the setting for Meniscus Vacuum. Ink jetting devices operate

under negative pressure to keep the meniscus at the edge of the nozzle. You may need

to adjust this depending on the viscosity and surface tension of your fluid. Four inches of

water is a typical value. Having the correct Meniscus Vacuum level usually affects the

high frequency performance of the fluid you are jetting.

Dimatix Materials Printer User Manual

FUJIFILM Dimatix, Inc. Confidential Information Page 24 of 93 DUM00001 Rev.09 Ver.1.3 09/06/06

The Tickle Control enables and controls low amplitude pulse that is given to the nozzle

periodically simply to move the meniscus slightly but not fire a drop. This is to help keep

the nozzle from “skinning over” with a thin layer of material left from fluid evaporating. The

“tickle” function is completely adjustable, and is very important for some fluids and not

required for others.

The low amplitude pulse that tickle control sends to the nozzle can be modified in the

waver form editor window as the non-jetting waveform. The frequency set in tickle control

is always active when the printer is not printing. This includes the times during which the

carriage is above the maintenance pad, on its way to the selected print area or on its way

back from one print pass to start the next pass. However, during printing, the tickle

frequency is the same as the firing frequency set in the wave form editor. So during one

print job, the printer repeatedly switches between the two pulses.

FUJIFILM Dimatix, Inc. Confidential Information Page 25 of 93 DUM00001 Rev.09 Ver.1.3 09/06/06

The Cartridge tab’s Jets to Use function allows you to select only the range of nozzles

you wish to use to jet your pattern, if you want to use fewer than all sixteen. The software

will automatically compensate for the # of nozzles used but the nozzles selected can only

be one series of adjacent nozzles.

The Cartridge Print Height sets the distance of the printhead above the substrate during

printing. It can be adjusted from .25 mm to 1.5 mm. Take care to set the substrate

thickness and Cartridge Print Height accurately to avoid hitting the substrate during

printing.

The Cleaning Cycles tab let you control how the print cartridge is cleaned before, during,

and after printing. Some fluids do not need periodic maintenance, while others need a

high amount of maintenance to keep nozzles clear and functioning properly.

• The Select button lets you select an existing cycle in the cleaning cycle folder.

• The Edit button lets you edit that cycle with the editor window.

• Start of Printing refers to the cleaning you want to do at the beginning of the print.

Select a cycle you wish to run to enter one in that box or you can edit an existing

file with the edit button.

• During Printing refers to the cleaning cycle you want to run while printing your

pattern. This can be set to run every so many number of bands (one cycle of the

carriage across the platen and back is a band) or every so many seconds of

printing time. Select a cycle you wish to run by clicking on Select and choose one

from the folder or you can edit an existing one with the Edit button. Whichever is

Dimatix Materials Printer User Manual

FUJIFILM Dimatix, Inc. Confidential Information Page 27 of 93 DUM00001 Rev.09 Ver.1.3 09/06/06

more frequent between Run every x bands Or Seconds (depending on printing

speed) is the cycle that will be used During Printing.

• End of Printing refers to the cleaning you would like to do at the end of your

printing. Select a cycle you wish to run to enter one in that box or you can edit with

the edit button.

• While Idle refers to any cleaning you would like to do while the system is not

printing but is on and you have a cartridge installed. Select a cycle you wish to run

to enter one in that box or you can edit with the edit button.

• None can be entered into any box that would have a file name to indicate not to do

any cleaning during that time.

• 0 can be entered where numbers are required to indicate not to run that cycle.

Cleaning Cycle Editor

The Cleaning Cycle Editor can be run by clicking the Edit button by any of the cleaning

cycles or by selecting Cleaning Cycle Editor from the Tools menu. From this editor you

can create sequences of operations that can be saved as a cleaning cycle file. Refer to

the Cartridge maintenance section in the back of the manual for more details. The default

cleaning cycle, Spit Purge Spit, is shown below:

• Spit refers to firing the nozzles for the designated time and frequency.

Dimatix Materials Printer User Manual

FUJIFILM Dimatix, Inc. Confidential Information Page 28 of 93 DUM00001 Rev.09 Ver.1.3 09/06/06

• Purge refers to pushing fluid out through the jetting device with pressure (system

is preset to 5psi). This process is usually used to get air out of the jetting device.

• Blot refers to the cartridge simply coming down and making contact with the

cleaning pad for the designated time. * Note: It is important to make sure that the

cleaning pad is not saturated or clogged to ensure good removal of the fluid from

the nozzles after purging or spitting.

• The Delay time is the time after the cleaning before going to the next step in the

cycle.

A cleaning cycle can be very simple, such as a “2 second blot” or they can consist of

several combinations of actions (spitting, purging, and blotting) with varying times.

Here is how to create a Cleaning Cycle:

• Click on the Spit, Purge, or Blot.

• Then enter a number or use the arrows for the Time, Frequency or Post

Delay that you want.

• Click the Add button and that will enter it into the table and incorporate it

into the cycle.

• If you want another action to occur next, simply repeat the process.

• If you want to delete a step, highlight it in the table by clicking on it, then

click the Delete button.

• When you have built your cleaning cycle, save it (by going to File-Save As)

with a name that describes what it does. That way you can easily identify it

in the folder in the future.

If desired you can run the Cleaning Cycle you just created by clicking on the Run Now

button.

Also under the Tools option in the Cartridge Settings window you will find the

Waveform Editor. Click on the Waveform Editor.

width at once. This is useful when you are using fluids with different densities. Higher

densities generally need longer pulses. Enter a number in the box then click the Rescale

Waveform button. The entire waveform’s width will change by multiplying its current

width by the Rescale number. For example, if you enter 1.1 in the Duration Scalar box, it

will adjust each waveform segment’s length proportionally to multiply the waveform’s

overall width by 1.1, which is a 10% increase.

Width – This box displays the overall pulse time width for the entire waveform.

Maximum Jetting Frequency – This is a number the user can enter to prevent the DMP

from jetting the fluid at a frequency higher than that which may have been determined as

the upper stability limit through drop watching. It also sets the scale for the Firing

Frequency Maximum in the Drop Watcher.

Note: The DMP will always try to print with a carriage speed of 300mm/sec unless it is

Maximum Jetting Frequency limited.

Non-Jetting Waveform

The Non-Jetting Waveform can be modified by clicking on an individual segment and

moving it. The instructions are in the box to the right of the graph.

Jetting Waveform vs. Non-Jetting Waveform

When the printhead travels over the print area, the software automatically tells it which

nozzles to fire and which are idle. The idle nozzles still get a small amplitude signal

transmitted to them. This is the Non-Jetting Waveform. The firing nozzles get addressed

with the Jetting Wave Form.

The Non-Jetting Wave Form is also the pulse signal that the Tickle Control sends to

the printhead during non-printing times when the carriage is above the maintenance pad,

or when it is moving to the defined print area or moving between two print passes. This

keeps the fluid in the nozzle in motion and helps prevent it from drying out.

Replacing Cleaning Pad

Located in the Tools pull down menu on the main screen is a feature called Replace

Cleaning Pad. You will want to replace the cleaning pad with a new one when it gets

filled with fluid or clogged by fluid residue and does not effectively blot the nozzle surface

of the cartridge, or you are changing cartridge fluids and don’t want cross contamination

from contacting the previous material on the cleaning pad.

To replace the cleaning pad select Replace Cleaning Pad from the Tools menu. The

cartridge will move to allow access to the pad.

DO NOT open the printer lid until told to do so. Opening the lid while the printer is in

motion will necessitate a re-initialization of the printer motors.

Open the lid and replace the pad.

Replace the pad by:

• Taking the top clear cap of a new Cleaning Pad assembly and push it down on the

old pad until you hear a click and then simply pull it out.

Dimatix Materials Printer User Manual

FUJIFILM Dimatix, Inc. Confidential Information Page 33 of 93 DUM00001 Rev.09 Ver.1.3 09/06/06

• Insert the new pad and holder by pushing the pad and holder down into the spot

where the old one was until you hear a click.

*Be careful not to remove the cleaning pad by itself. This may damage the springs

holding the receptacle which will then not position it correctly.

When the lid is closed the carriage will move back to the cleaning station.

Pattern Printing

Note: If you are printing a pattern on a substrate that you will either remove and

reposition, or change cartridges, be sure to set the Printing Origin before printing the first

pattern.

Select Pattern

The following screen allows you to pick a print pattern file that has already been created,

or to create a new one.

Create Your Own Pattern

The Pattern Editor allows you to create or modify pattern of drops for printing, and easily

repeat it if desired onto a substrate. The basic pattern of drops at the lowest level (the

Pattern Block Array table) is user-defined as a collection of rectangles. Each rectangle

in the table may be small enough to represent a single drop, or thin enough to represent a

line of drop, or large enough to represent a filled-in rectangular area.

In all cases, X increases to the right, and Y increases toward the front of the printer. All

dimension parameters are in millimeters except for the Drop Spacing, which is in

microns. All dimensions entered into the pattern generator are rounded onto the Drop

Spacing which is the spacing between drops to form a pattern feature.

By selecting the Edit button on the Select Pattern screen the following screen appears:

Dimatix Materials Printer User Manual

FUJIFILM Dimatix, Inc. Confidential Information Page 36 of 93 DUM00001 Rev.09 Ver.1.3 09/06/06

Substrate

The Dimensions is the total area that will be printed. Generally most people will jet on

only a single substrate. But you could place several smaller substrates on the platen and

jet on all of them at once. Verify that the total area is not larger than your substrate.

The Leader Bar is a vertical bar that can be jetted (by checking the Enable box) which

will precede your pattern. This is often used to “pre-fire” nozzles to keep them active and

their drop velocity uniform to improve pattern quality. The Width of it and the Gap of the

Leader Bar can be entered in the boxes.

The Drop Spacing is the center to center distance from one drop to the next in X and Y

position to create the pattern. This can be adjusted in 1 micron increments with a

minimum of 5 microns. Usually a drop spacing around 20 microns gives good printing

results. The X spacing is controlled by the x axis encoder, while the y axis is controlled by

the cartridge angle.

The Layers box feature allows you to reprint the same pattern over itself automatically.

The Count number is the number of times you want to print the pattern and the

Interlayer Delay is the delay time between each layer, additional to the amount of time

spent doing any Before Print or After Print maintenance on the cartridge.

If you click on the Preview Drops button a window will pop up showing the area you have

designated. The total area of the window represents the platen. If the substrate area you

entered is smaller than the platen it will show as a beige shape inside the white area.

Dimatix Materials Printer User Manual

FUJIFILM Dimatix, Inc. Confidential Information Page 37 of 93 DUM00001 Rev.09 Ver.1.3 09/06/06

Your Pattern Block Array area is delineated within the substrate area outlined.

Pattern Block Array

In the Pattern Block Array box enter the point on your substrate where you want the

pattern to start printing in X and Y, referencing from the print origin. Then enter the X

width and Y height of the block you want to make. The X and Y sizes entered should be

at least large enough to enclose the collection of rectangles defined in the Pattern Block

Drop Positions (see below).

Note: The default print origin is approximately -1 mm, 7 mm (x,y) from the 0,0 corner

scribed in the back left of the platen.

To print a repetitive array of the pattern block in your print area, enter the X and Y Pitch

dimensions. The Pitch is the distance from the start of one pattern to the next. Enter the

number of repetitions (X count) to print in the horizontal direction, and the number of

repetitions (Y count) to print in the vertical direction.

Dimatix Materials Printer User Manual

FUJIFILM Dimatix, Inc. Confidential Information Page 38 of 93 DUM00001 Rev.09 Ver.1.3 09/06/06

Pattern Block Drop Position

The pattern generator works with one or more user-entered rectangles of X width by Y

height. When you enter the dimensions of your feature in the appropriate boxes and click

the Add button, it will be placed in the table on the bottom of the window.

Note: Only those rectangles that are added to the table on the bottom of the pattern

editor window get saved once you are done creating your pattern.

In the Pattern Block Drop Position box:

• Enter the position (X and Y) where you want to place the first drop in your Pattern

in the Pattern Block.

• Then enter the Length and Height of the “feature” you want to create. For lines,

enter the width height of the line that you want. For example, for a horizontal line

you would enter how long you want it to be in the x direction (X, width), maybe 10

mm, and for 200 microns “tall” you would enter 200 microns for the Y Height. For

the same vertical line, it would be 200 micron X width, and 10mm Y height. To

define a feature that is a single row of dots or a single dot, use a dimension or

dimensions smaller than the Drop Spacing parameter

• The Increment Value is the value at which you want the dimensions to change

with each click of the arrow buttons. For example and Increment value of 1.000 will

change the dimension 1 mm for every click of the arrow. The Increment vale gives

you a convenient way to generate a set of related rectangles.

* You can also very easily create a rectangle by placing the cursor on the Preview

Drops window, place the cursor in a Block, hold the Shift key down and “point,

click and drag” to create a rectangle.

If you click on the Preview Drops button, a window will pop up which shows you the

pattern. When you click on a line of data in the table specifying a feature, that feature will

show up in red on the Preview Drops screen. You can Zoom In on the feature by

clicking on the “+ magnifying glass button” to where you can see the individual spots.

When you Zoom In it is best to have Show All Patterns de-selected to reduce data

crunching. You can continue Zooming in until you see the grid background. Then when

you hold the Ctrl button on the keyboard and point and drag the left mouse button on

Dimatix Materials Printer User Manual

FUJIFILM Dimatix, Inc. Confidential Information Page 39 of 93 DUM00001 Rev.09 Ver.1.3 09/06/06

your feature of interest you can zoom in and it will stay centered on the screen. You can

also zoom in by hold down the Ctrl key on the key board, placing the cursor on your point

of interest and clicking. This will zoom you to the individual drop and grid level.

You will see grey lines on the screen which represent the pattern as you created it in the

Pattern Generator. The dots are actually where the drops will be placed as the

dimensions are round to fit on the grid you have defined in the Drop Spacing.

Dimatix Materials Printer User Manual

FUJIFILM Dimatix, Inc. Confidential Information Page 40 of 93 DUM00001 Rev.09 Ver.1.3 09/06/06

If you highlight a line in the table and click the Add button you will duplicate that feature. It

will be jetted right on top of itself unless you change the x and y start points, which you

can do by highlighting that data line in the Pattern Generator table and then changing the

numbers in the appropriate boxes.

The Preview Spot Size box let’s you enter the diameter of the spot that a single drop

makes on your substrate. This is helpful to visualize how much separation or overlap of

drops you have in the pattern features depending on their size and the Drop Spacing

used. When reviewing the pattern to see how the features match the grid or how

adjoining features line up set the Spot Size to 10 microns.

The Enable Spot Size feature allows you to zoom in on the image and view the individual

spots of your pattern. Putting a check in the box by clicking on it enables it. Click on it to

disable it to view all of the patterns.

The Show All Patterns feature enables you to see all the patterns on the substrate when

checked.

The 1x button feature displays you pattern on the screen to very close to its actual size.

Drop Spacing

The Drop Spacing is the distance in X and Y, center to center, of the drops that the DMP

will deposit to create the pattern. Drop Spacing is adjustable between 5 and 254 microns

in one micron increments. It will toggle with the arrows on the box in five micron

increments. For example, with a 50 micron Drop Spacing, the pattern generator will place

drops 50 microns apart in X and 50 microns apart in Y to fill in your pattern. So, for a 100

micron wide, 10 mm tall vertical line, the system will place 3 drops in the X direction (one

for the first edge, another at 50 microns, and another at 100 microns for the next edge) by

2,001 drops tall. The Drop Spacing therefore determines your resolution or density in the

X direction and determines the angle at which the cartridge must be set to get the same

resolution or density in the Y direction. The Drop Spacing parameter is most useful for

altering the fill density (amount of jetted ink per unit area) of lines and rectangles, or it

Dimatix Materials Printer User Manual

FUJIFILM Dimatix, Inc. Confidential Information Page 41 of 93 DUM00001 Rev.09 Ver.1.3 09/06/06

may be used to create rows of individual drops which are spaced closer together than

254 microns. When you create a pattern the dimensions and locations of the features

should be divisible by the Drop Spacing for optimum placement matching. If not there

may be some shift the features.

Nozzle Test Pattern

There is a 16 line test pattern which can be run to see the performance of each nozzle

individually. This is done while on the Print Set-up window by holding down the control

key on the key board and clicking on the Print button on the bottom right of the window.

Set the cartridge to 90 degrees before running the pattern.

BMP and Gerber File Printing:

To import BMP files or Gerber files into the DMP Software, select Tools on the main

screen. Then select Pattern Editor (Bitmap images). This will open the Image to

Pattern Converter window. Then under File, select Open BMP or Open Gerber to open

your file. *The Gerber Tools option must be loaded in the system for Gerber File

conversion.

Gerber Files

To open a Gerber file, set the drop spacing you want the image printed to and then select

‘Open Gerber’ from the File menu. Select the Gerber file you want.

*The Gerber file will be processed into a BMP at the selected drop spacing resolution.

All of the controls will operate as if it was a BMP file with the exception of drop spacing

and X Width, Y Height. Since a Gerber file is resolution independent, changing the drop

spacing does not change the dimensions of the output.

*If you change the Drop Spacing you must then save the file for it to be processed at the

new drop spacing.

The Substrate Tab has the following features:

o Substrate Dimensions – this is the calculated minimum size of a substrate that

will be needed to print the pattern

o Leader Bar – This is the same as in the Pattern files. This is a vertical bar that

you may add to your pattern to enhance printing quality.

o Drop Spacing – the same as in Pattern Printing, this is the spacing of the drops

(center to center) in x and y that will be jetted to create the pattern. The x spacing

is encoder controlled and the y spacing is set by the cartridge angle.

o Layers – this is the same as in Pattern Printing and allows you to re-print the

same pattern over itself several times (Count) with or without a delay (Interlayer

delay).

The ‘Full’, ‘Fit’, ‘Zoom’, and ‘Pan’ enable movement and zooming of the image. When

an image is first loaded it will zoom to ‘Fit’. This shows the full extents of the bitmap.

Dimatix Materials Printer User Manual

FUJIFILM Dimatix, Inc. Confidential Information Page 43 of 93 DUM00001 Rev.09 Ver.1.3 09/06/06

Clicking the ‘Full’ button will zoom in on the image to the point where each pixel in the

BMP file is displayed as a pixel on the screen. The form may be resized to provide a

larger preview.

If the Zoom button is selected, then clicking and dragging the left mouse button over the

image will create a zoom window. When the mouse is released the image will zoom to the

selected area. If ‘Pan’ is selected, clicking the left button and dragging in the image will

move the viewable image in the window. These controls can be used to view the high

resolution data and aid in selecting the reference point.

Tiled Preview allows viewing of all the patterns to be printed.

Placement / Tiling

Dimatix Materials Printer User Manual

FUJIFILM Dimatix, Inc. Confidential Information Page 44 of 93 DUM00001 Rev.09 Ver.1.3 09/06/06

Placement:

X Start, Y Start is the position relative to the Printing Origin that the pattern will start.

X Width, and Y Height is the calculated size of the pattern.

Tiling:

This is used to make multiple print copies of the same pattern. The Pitch is the distance

from the beginning of one pattern to the next as set in X pitch and Y pitch. The number of

patterns is set by the Count.

Reference Point:

The X Ref, Y Ref, ‘Locate Ref Point’, and ‘Set Ref Point’ provide an additional way to

position the image by aligning a point in the image to a specific point on the substrate (a

point is selected in the image and a corresponding point is selected in the Fiducial

Camera form).

Dimatix Materials Printer User Manual

FUJIFILM Dimatix, Inc. Confidential Information Page 45 of 93 DUM00001 Rev.09 Ver.1.3 09/06/06

• To print using a Reference Point in your image, check the box “Use Reference

Point”

• To set a Reference Point, first locate the part of the image you wish to align to by

either using Zoom or Pan. Click ‘Set Ref Point’. Then place the cursor on the

point in the image. You can make fine adjustments by clicking the arrow up/down

buttons next to the X Ref and Y Ref fields. If you know the dimensions for the

Reference Point you can type them in directly into the X Ref, Y Ref boxes then

click ‘Locate Ref Point’. This will take you to that specific point in the image. The

cross hair cursor that displays the reference point will show when the pattern is

printed.

• To complete the Reference Point usage, go to the Fiducial Camera window (see

Fiducial Camera section). Click on the Fiducial Camera button on the main Drop

Manager window to open the Fiducial Camera.

• In the Tools menu of the Fiducial Camera click on the “Set Reference Point”

button. Click OK on the pop up window.

• Find the point on your substrate where you want to place your selected image

Reference Point by moving the camera to the desired position. Place and click the

cursor on your point.

• Click the “Use Reference Point” box on the Fiducial camera window.

• Do not close the Fiducial camera window before you print. It must stay open.

Simply click the Print button on the main Drop Manager “Print Set-Up” window.

The X Width and Y Height values are filled in when a file is loaded. The size is based on

the image size and the drop spacing. BMP files must be printed at the Drop Spacing

(resolution or dpi) they were created for, or the image size will change accordingly.

A status bar at the bottom shows the current Zoom Factor, the location of the upper left of

the preview, and the Image Size. The current cursor position is also displayed.

FUJIFILM Dimatix, Inc. Confidential Information Page 46 of 93 DUM00001 Rev.09 Ver.1.3 09/06/06

When all of the parameters are correct you must save the file as a pattern file (it has a .ptf

extension). The pattern file is what can be selected from the main form or the fiducial form

to print.

Print Preview

The Print Preview can be disabled or enabled in the Main Dimatix Drop Manager Form

'File' menu. If it is on, it will show a preview before the printing starts. The Title Bar of the

dialog tells if the reference or printing origin is being used. The origin (or reference

point) is marked with a cross hair. The Leader Bar is shown if it is enabled.

The preview is sizable so it can be made full screen for more detail. Remember, the

platen area is not the substrate! The user has to make sure the substrate is placed

correctly on the platen and that it will fit the image they are going to print. The preview is

meant to make sure they have set the origin and tiling correctly.

Cartridge Mounting Angle

Before you jet your pattern, the system will calculate the angle to set the cartridge

determined by the Grid Spacing specified in the pattern. This angle adjustment is what

allows the user to modify the drop spacing in the Y axis.

The following is a top view of the carriage. There are two sets of scales. The outer scale

is the cartridge angle scale, and the inner scale is the vernier scale to adjust the head

angle to 0.1 degree increments. Release the latch by pulling it forward freeing the

The following is a close-up of the cartridge angle alignment scale set to 0 degrees. The

outer main scale is in one degree increments. There is a notch on the 0 point of the inner

vernier scale is lined up with the 0 on the outer cartridge angle scale.

The following picture shows how to set the cartridge angle to 11.4 degrees. The 0 notch

on the inner vernier scale is a little past the 11 degree mark. The next inner mark on the

vernier that is lined up with a mark on the outer ring is line 4. This gives 11.4 degrees. If

you wanted to set the cartridge angle to 11.5 degrees, then you would move the inner

ring a little more to get the 5th mark lined up with a mark on the outer ring.

Drop Watcher

In the bottom left of the screen is the Drop Watcher button. Clicking on it will move the

carriage to the right side of the platen, positioning the jetting cartridge’s nozzles over the

Drop Watcher Camera system. This system allows direct viewing of the jetting nozzles,

the faceplate surrounding the nozzles, and the actual jetting of the fluid. The Cartridge

Settings window also comes up at this time to allow you to modify the drive waveform

and view the changes in jetting characteristics.

Note: Tickle control will be not active (displayed in gray) when you open the cartridge

settings window via the Drop Watcher. In order to be able to change tickle control, open

the cartridge settings window directly by clicking the edit button in the print setup tab in

the DMP main program.

Once the carriage and cartridge are in position, click on the Viewing Nozzle box –

number 8 should in the box. When you click on it, the system will bring nozzle number 8

of the cartridge into the center of the screen. You can then increment up or down to

different nozzles and the system will move that nozzle into position in the screen. There is

also a list of the nozzle numbers across the screen in which you can turn any of them on

or off. By clicking the box associated with each nozzle it will fire that nozzle or turn it off.

To minimize spraying off of the absorbent Drop Watch Pad, the user interface limits

selecting jetting nozzles to the four surrounding the Viewing Nozzle.

If you want to do a maintenance cycle to improve jetting, you can do that by clicking on

the Run Now button on the Cleaning box.

Dimatix Materials Printer User Manual

FUJIFILM Dimatix, Inc. Confidential Information Page 52 of 93 DUM00001 Rev.09 Ver.1.3 09/06/06

There are also two arrow buttons near the bottom left of the screen, which allow you to

focus the camera on the nozzles and drops by clicking repeatedly until the image is in

focus.

The drop watcher system provides you with two different viewing modes, selected under

Viewing and Capture Control.

• If you click on Movie Mode box, this allows you to watch a stroboscopic “movie” of

drops in flight as they are ejected from the nozzle. This is real time continuous

firing of the nozzles. Clicking this box also changes the Image Title and Capture

Image to either Image or Movie.

• If Movie Mode is not checked, then the drops appear to be frozen in flight for

closer inspection and measurement. By adjusting the strobe delay you freeze the

drop at different positions after it leaves the nozzle.

• You can click on the various nozzles to see how they perform.

• In Tools there are different versions of the video window’s Graticule or scale

available.

Dimatix Materials Printer User Manual

FUJIFILM Dimatix, Inc. Confidential Information Page 53 of 93 DUM00001 Rev.09 Ver.1.3 09/06/06

• The Image/Movie Title button allows you to put a title at the bottom of the screen

in the image after “Dimatix DMP2800” – Your Title Here. The nozzle number that

you are viewing, the firing voltage, the cartridge temperature, the waveform file

name, and the date and time are automatically stored on the image.

• Under Tools, the Display Image Information allows you to turn on or off the

image information.

• The Capture Image/Movie button allows you to store a still image video of the

jetting with all the conditions information on it.

• When in Movie Mode the Configure Capture Quality button allows you to adjust

the quality (and subsequently the file size) of the image by clicking on the Settings

tab in the window that pops up. The dialog displayed will depend on the type of

video interface installed in your system. A system with a Pinnacle Dazzle card

(which is an external video device) will display the following:

If a PCI video capture card is installed internal to the PC, the following will

appear:

• The Drop Viewing Speed slider changes the sweep rate of the delay of the strobe

while in Movie Mode. This has the effect of making the appearance of drop

formation go faster or slower.

• The Drop Refresh Rate slider adjust the time at which the sweep delay starts over

thereby adjusting how long you see a drop in flight.

The Firing Control box allows you to adjust the Firing Frequency while you are jetting

to observe the effects by clicking on the slide the bar with your mouse and dragging it.

The minimum frequency is 1 kHz.

• The Strobe Delay lets you set the time after the drop fire pulse at which the strobe

LED fires to capture the drop image. This can be adjusted with the slide bar also.

FUJIFILM Dimatix, Inc. Confidential Information Page 55 of 93 DUM00001 Rev.09 Ver.1.3 09/06/06

This has the effect of freezing the drop in flight. Clicking on the Delay 100 us

button automatically sets the delay to 100 us after the fire pulse. When you set the

nozzles on the 0 um line on the screen with the Graticle on you can measure drop

velocity. For example, with a 100 usec strobe delay you are seeing the drop after it

has traveled for 100 usec. If the drop is at the 500 um line then the drop’s velocity

is 5 meters per second. This feature will come in handy when switching cartridges

as you will want to match drop velocities by adjusting voltage to the nozzles to get

consistent results. A good velocity to set is between 7 – 9 m/sec.

The Tools tab for this screen lets you select different features.

o Graticule – This places a scale on the screen for velocity and drop

formation measurements. The choices are: None, Left, or Full. Click on the

one you want to use.

o Calibrate Nozzle View – This feature automatically controls the stage

motion to keep the nozzles in line when drop watching regardless of the

cartridge angle. To perform this operation follow the following procedure:

- Start by clicking on Calibrate Nozzle View.

- The screen image should be close to nozzle 1. Find nozzle 1 (the

rightmost orifice), put mouse pointer on the nozzle and click-drag it to

the cross-hair on the screen. Use the focus buttons as necessary to

refine the nozzle’s focus.

- Click the Next button and drag the image to the right until nozzle 16

(the leftmost nozzle) is under the cross hair. Use the focus buttons

again as necessary to refine the nozzle’s focus.

- Click Next again and you are done calibrating the nozzle view. Now,

when you select any nozzle from one to sixteen, the selected nozzle

should be close to the 0 line opening, and in focus.

- For the stage to move the selected nozzle into position you must

index through the nozzles using the Viewing Nozzle box. When you

open the drop watcher it will try to center nozzle #8 in the middle of

the screen and put nozzle 8 in the Viewing Nozzle box. By clicking

the cursor in the box it turn the nozzle on and move it up to the 0 line.

o View Cartridge settings – this allows you to open the cartridge settings

form if they were closed.

o Drop Volume Measurement - this is a procedure that will allow you to

measure drop volume by using an average drop weight technique.

The flowing screen shots show the procedure as it appears on the system

when you are running it. You begin by opening the Drop Watcher window:

The following note explains to wait until the carriage moves into position and stops. A

general note to remember he is that the DMP lid is the safety interlock. Opening the lid

When the carriage moves over into position it is about 25mm above the platen surface.

To begin with you need a container that you have weighed and that will fit under the

carriage. It is best to use one that is shallow that the carriage can be lowered close to the

Adjust the carriage as close as you can to the bottom of the container. This will yield more

accurate results.

You want to weigh as many drops as practical to get a more accurate number. The

number of nozzles you have selected to fire in the drop watcher before opening this menu

will show up on the form. The frequency you set it the Drop Watcher will be the firing

frequency for this procedure. The following form shows 7 nozzles have been selected.

The default time period will be calculated based on the frequency and number of jets to

get close to 1 million drops. Adjust the time to change the number of drops jetted.

Once it finishes jetting you are ready to calculate the drop mass after weighing the pan.

Drop Watcher Pad

The Drop Watcher Pad is located in the center of the Drop Watcher mechanism

and acts as the receptacle for fluid during jetting. It will need to be changed

periodically as it absorbs fluid. Typically this occurs when you see stray drops

being deposited on the nozzle surface during drop watching or fluid is covering the

side of the Pad holder. To replace the pad simply pull out the holder and insert a

new one.

Fluid Requirements

Some of the fluid physical characteristics to achieve optimum performance are:

• Viscosity – 10-12 centipoise at jetting temperature

• Surface Tension – 28-33 dynes at jetting temperature

• Low Volatility – Boiling points higher than 100 deg. C are preferred

• Density – Specific gravity greater than 1 is beneficial

• Degassing – Additionally the fluid may need to be degassed to remove any

dissolved gas which inhibits jetting. Typical degassing can be done with a vacuum

(a negative pressure of 2 psi for 1-2 hours maybe sufficient or up to only 50mbar),

by using ultrasonic, or by spinning (fully miscible solutions only).

Refer to Dimatix Application Notes at www.dimatix.com for more information.

Dimatix Model Fluid MFL-002

This fluid is a non-toxic, non-hazardous, non-drying fluid used in our testing and qualify

printheads and jetting assemblies.

• The surface tension is 33 (+/- 3.5 dynes/cm) at jetting temperature. A polymeric

dye was selected to color the fluid.

• The jetting temperature for Model Fluid 2 is 30°C, resulting in a typical viscosity of

11 centipoise.

The following are typical jetting results that the user may see from jettable fluids.

Drop Velocity vs. Frequency

Here you will see that higher viscosity fluids will have lower velocity and a better high

frequency performance due to their dampening effect. Higher voltages to the cartridge are

required for higher viscosities.

Dimatix Model Fluid. You can see that after the drop leaves the nozzle it has a tail. The

liquid on this small scale is mostly influenced by cohesive forces within the fluid. Here not

all of the tail collects into the main drop again. But you get a small drop of ink following

the main drop. Switching to lower voltage leads to less tail. You could reduce the

frequency, change the waveform, or a combination of these to get your desired drop

formation. These drops were fired with 25V.

• Push the two halves straight together until the SECOND snap is felt and heard.

This is a fairly rigid connection and takes a fair amount of force.

• Once the two pieces are snapped together the fluid can flow into the jetting device

of the cartridge. * Let the cartridge set for 30 minutes with the nozzles facing down.

At this point care must be taken to protect the nozzles of the cartridge. If the fluid is

very low surface tension it may flow out of the nozzles. If it is highly volatile it may

start drying at the nozzle leaving residue and thereby preventing it from jetting. It is

best to immediately place the filled cartridge in the DMP.

Cartridge Maintenance

The DMP contains hardware and software to perform one or more maintenance activities

which are designed to initialize and maintain optimal jetting performance.

• The Cleaning Station contains an absorbent pad to draw ink off of the nozzle plate

when it is brought close to it. It does not actually touch the nozzle surface but

rather it contacts the face plate around the nozzle plate. The pad is replaceable.

• The Cleaning Station uses air pressure to pressurize the outside of the ink bag,

which forces ink out through the nozzles. This is mainly used to initially prime the

cartridge, but also as a method for reviving problem nozzles. The DMP includes a

pump for this function, which is also used for meniscus control.

Specific functions include:

• “Purging” process pressurizes the cartridge to push fluid out the nozzles to

remove trapped air to prime or clear the nozzles.

Do not dispose this product as unsorted municipal waste. Collection

of such waste separately for special treatment is necessary.

(Entsorgen sie dieses Produkt nicht als unsortierten Hausmüll. Eine

• “Spitting” is firing the nozzles at a selected frequency and duration. Tickle mode

sends a non-firing pulse to the nozzles keeping the ink in motion at the nozzle

plate to help keep it ready to fire.

• “Blotting” is when the cartridge lowers to the Cleaning Pad so that the pad can

adsorb excess fluid from the nozzle plate.

• Meniscus Control is a low level vacuum applied to the ink reservoir to prevent ink

from flowing out of the cartridge nozzles.

Purging Applies air pressure to outside of

fluid bag to force fluid through

entire fluid path and out all

nozzles at once.

Required for initial use to force

air out of fluid path (prime).

Clear severely clogged nozzles.

Can also be used to lower

printhead temperature by purging

hot fluid and bringing system

temperature fluid into the flow

path.

Produces high flow rate of fluid,

so purge time should be

minimized for 1 ml cartridges.

Used as last resort for clearing

clogged nozzles.

Spitting Ejecting a predetermined

number of drops at a

predetermined frequency from

one or more nozzles.

Clears the nozzles, brings fresh

fluid to the pumping chamber

and nozzles, keeps fluid path

surfaces wet.

Consumes ink that cannot be

used for printing. Typically used

on a periodic basis, e.g. every X

printing passes or every Y

seconds, to maintain robust

etting performance.

Blotting Bringing an absorbent and/or

wicking medium in close

proximity to nozzle plate (may

lightly touch) to remove excess

fluid from the nozzle plate. No

wiping action.

Fluid puddling around nozzles

can partially attach to ejected

drops causing misdirected firing.

In extreme cases, puddled fluid

will flood the nozzle and prevent

firing altogether. In addition,

excess fluid on the nozzle can

fall or be flung off onto substrate

or printer components.

Risk of cross contamination

when switching cartridges of

diffeent fluid if the Cleaning Pad

is not changed.

Tickle Mode Exercising the pumping chamber

at low amplitude to rhythmically

pulsate the nozzle exit meniscus.

Retards "skinning over" of nozzle

exit meniscus. Keeps nozzle exit

wet.

May be sufficient to keep nozzles

"alive" for lower volatility fluids as

an alternative to spitting. Used

while head is capped, or for low

use nozzles during printing.

System Faults

There are several error messages that may occur during operation of the DMP. In these

cases you will usually get a message to power off the DMP and then power it back on. If

the problem is not remedied by turning the DMP off (leave off for 5 seconds minimum)

and then back on, the system will have to be returned to FUJIFILM Dimatix for service.

Faults

• "The cartridge drive amplifier has malfunctioned."

This is an error in the Amplifier calibration. Try replacing the jet cartridge.

• "The platen heater is malfunctioning."

This is a result of the platen heater having a short or an open.

• "A motor has malfunctioned"

One of several motors has detected an error. Check for material blocking the

platen or carriage movement.

• “Driver error”

• “Encoder index”

• “Home sensor”

• “Movement error”

• "The printer's 3 volt power supply has malfunctioned.”

• “The printer's 5 volt power supply has malfunctioned."

• "The purge pressure is too low."

• "The cartridge meniscus vacuum can't be controlled."

• "The printer's internal memory has failed."

• “The printer CPU firmware upgrade has failed."

In this case the system will ask you to “Try Again.”

• "The printer FPGA upgrade has failed.”

In this case the system will ask you to “Try Again.”

• "An undefined printer error has occurred."

Preventative Maintenance

Carriage

When installing cartridges, inspect the connector on the carriage holder. If you see any

fluid on the connector, wipe it off with a clean lint free cloth or other similar material.

Additionally, wipe any other fluid or debris from the holder area.

Inspect the pressure seal area on the cartridge holder also. Make sure it is free of debris

to ensure that proper pressure regulation can occur.
