1-1. Precautions

Please observe the following precautions before using your printer.

z GT-3 represents the common specifications of GT-381, GT-361 and GT-341 models. The individual specifications

are described with each model name.

z Please advise the following to your customers who buy your printed materials:

z Printed colors may transfer when a printed surface rubs on a white or light-colored synthetic leather made of

PVC (polyvinyl chloride). When printing CMYK-only garments, the CMYK ink may transfer to the White-only

printed garment when they rub against each other. In those cases, clean the stains with a soft cloth or

toothbrush with a household cleaner or alcohol.

z Wash away the pretreatment halo marks.

z The printer is designed to be used within the temperature and humidity levels below. Less humidity may cause ink

clogging in Print Head nozzles and higher temperature may cause splashy print result. Use the printer within the

range of our recommendation for the best print result.

Temperature Humidity

Keeping your printer 32 °F to 104 °F

(0 °C to 40 °C)

20 % to 85 %

(no condensation)

Operating your printer 50 °F to 95 °F

(10 °C to 35 °C)

For the best print result 64 °F to 86 °F

(18 °C to 30 °C)

35 % to 85 %

(no condensation)

z Do not pull out Ink Cartridge(s) during the operation; it may result in poor print quality or cause damage to your

printer.

z Do not turn off your printer, or open the Front Cover during the operation; otherwise the printer may be damaged or

spoil the print job.

z Be careful in handling a printed T-shirt that has not yet fixed by heat. Ink is difficult to wash from stained clothes.

z Clean the Caps and Wipers, replace the Wiper Cleaners, Fan Filter, Roller Felts (4), Flushing Plate Sponge (top)

and Flushing Plate Felt (bottom) according to our maintenance schedule to maintain good print quality. Those

Maintenance Parts are packed together in White, Cyan and Magenta (except 180 cc) ink Cartons. Replace them

when you open the new ink cartridge or you see the warning indicated on the display. Print quality may be

damaged by insufficient cleaning, e.g. dirty printed materials, mis-firing.

z Never use alcohol when you clean Head Caps and Wiper Blade; it will cause damage to the Print Heads. Use

Wash Liquid when you clean around the Print Heads.

z Install the Ink Cartridges in the correct positions as shown. Confirm both the colors of labels on your printer and the

Ink Cartridges.

z The printer indicates empty status "Empty XXXX (color)" when the ink cartridge is used up. Replace with a new Ink

Cartridge. Make a new Ink Cartridge available when the icon on the Operation Panel starts blinking. A small amount

of ink remains to avoid damage to your printer.

z New consumables should be stored away from direct sunlight until they are required. Use up the Ink Cartridges,

Pretreatment and Maintenance Solution before the expired date, and CMYK inks should be used up within six

months after opening the new one.

GT-3 Series

1. Read This First

z Never refill ink, never reconstruct ink cartridges; ink may cohere inside the cartridge bag, tube or even Print Head

and may cause serious damage to your printer. We assume no responsibility for any problem caused by using

them. Only genuine new ink cartridges should be used.

z The ink cartridges should always be installed; otherwise the needles may stopped up with ink and your printer may

be damaged.

z Tubes and Print Heads for White must be cleaned with Maintenance Solution once a week by the menu Tube

Cleaning. The Warning "Clean Tube W*" is indicated on the display of the Control Panel after a week passes since

the last Tube Cleaning.

z If the printer is unused for a period of time there is a possibility that Print Heads and Maintenance Unit may become

clogged as ink dries. To avoid this, we recommend that the printer should be turned on at least once a week and

press the Head Cleaning Button to clean the Print Head. If you are planning not to use your printer for more than

two weeks, follow “6-2-5. Required Maintenance for the Long Storage" to keep printer in good condition.

z Shake the White Ink Cartridges once a day before you start printing (30 seconds to 1 minute for each, 1-2 minutes

for new one). Hold the cartridge upside down to agitate the pigment in the bottom and shake it horizontally.

z If CMYK inks are printed on a Pretreatment applied T-shirt, ink may wash off. Do not apply Pretreatment when you

print without using White ink.

z The clearance between the Clearance Sensor and the surface of the Print Heads should be app. 2 mm. If the

clearance is wider, the ink mist will spread inside the printer and the printing material, and may damage the sensors

inside. If you print with wider clearance (more than 2 mm) then check the inside of the printer and keep it clean by

referring to "6-1-6. Cleaning the inside of the printer and restart" and "6-1-7. Cleaning the Encoder Strip".

z Pretreatment mist may spread out when you use a spray and/or pretreatment applicator. Ventilate your room in

operation. Wear a face mask or goggles as necessary.

z Pre-treatment on some T-shirts may be seen after applied and cured, wash lightly with water to remove mark.

Some dyes may be decolorized by Pretreatment; we recommend you test the garment before printing.

z Dispose the used waste ink, pretreatment, maintenance solution (all water-based) or other wastes in accordance

with your local regulations. Or make contact to your dealer.

z The pretreated area may turn yellow when you apply Pretreatment on a white or light-colored garment. Keep the

pretreated garment away from the sunlight and wash the printed T-shirt soon.

3. Getting Started

Before using your printer, it needs to be correctly setup as described in this chapter.

WARNING

Do not handle the power cord with wet hands, otherwise it may cause electric shocks.

Do not set up the printer in a dusty environment. If dust collects inside the printer, it may cause fire or

electric shocks or problems with correct operation.

Be sure to connect the ground. If the ground connection is not secure, you run a high risk of receiving

a serious electric shock, and problems with correct operation may also occur.

Do not bend the cords excessively or fasten them too hard with staples or anything similar to secure

cords, otherwise there is the danger that fire or electric shocks could occur.

CAUTION

Setting up and moving of the printer should only be carried out by a qualified technician.

The printer machine weighs approximately 111 kg (245 lb). Transporting and setting up of the printer

should be held in proper way. The machine may fall down and cause injury.

The printer must be used on a suitable stable surface, otherwise it may tip over or fall down and cause

injury.

Furthermore, the table that supports the printer should be at least 137 cm (53.9 inch) in width and

104.5 cm (41.1 inch) in depth, and should be able to bear a weight of 150 kg (330 lb) or more.

Do not set up the printer in a place where it will be affected by vibration. It may become unbalanced

and fall down, which cause injury or damage to the printer.

Do not connect the power cord until setup is complete, otherwise the printer may operate if the power

switch is turned on by mistake, which could result in injury.

Do not climb onto the printer or place heavy objects on top of it, otherwise it may become unbalanced

and tip over or fall down and cause injury.

4-1. Basic Printing Procedure

(1) Set the proper color settings and print conditions of the application. For precise editing and output, applications such as

Adobe Photoshop, Illustrator, CorelDRAW, Paint Shop Photo Pro are recommended, e.g. to deal with higher resolution

images (200 dpi or higher).

See “4-2. Setting the Applications’ Print Condition” for further details.

(2) Create the artwork using a suitable graphic application. Use RGB=254 (=254, 254, 254) white for white color. RGB=255

(=255, 255, 255) white (paper color) is transparent color with no ink printed.

(3) Select [ File ] > [ Print ] menu of your application an set Printer Driver conditions.

See “4-3. Setting the Printer Driver Condition”.

(4) Turn on your printer:

See “3-2-1. Turning On Your Printer”.

(5) Execute [ Daily Cleaning White ] to keep the whiteness of White Ink. See "6-2-1. Daily Cleaning White for replacing dull

White Ink". Test print for both CMYK and White and check the print quality. See "7-2-3. Checking Print Quality with

Nozzle Check Pattern".

(6) Send data to your Printer. Select Printer Driver: either GT-3 Printer Driver (USB 2.0 Cable) for direct print or GT-3

FileOutput Printer Driver to make print data file (.ar3).

As for sending .ar3 file to your Printer, see "5. Printing AR3 Files".

(7) Install the Platen of the size you have selected in step (3) "4-3. Setting the Printer Driver Condition".

See “4-4. Uninstalling / Installing the Platen”.

(8) Set the T-shirt (as for dark garments, pretreated. See "4-6-1. Applying the Pretreatment") on the Platen and adjust the

Platen height. The operation on the both platens (Left/Right) is the same. See “4-5. Placing the T-shirt on the Platen”.

(9) Press the Print Button on the Control Panel to start printing. See "4-6-2. Making One Print.".

(10) Remove the "printed" T-shirt from the Platen.

See “4-7. Removing the T-shirt from the Platen”.

(11) Fix the ink with heat onto the T-shirt.

Use a conveyer oven or a heat press to fix the ink onto the T-shirt. See “4-8. Curing the Ink onto the T-shirt”.

(12) Repeat (8) to (11) until all the prints are finished.

(13) See the Chapter 6 for necessary maintenance and for regularly and more-than-2-week storage.

(14) Turn off your printer. See “3-2-2. Turning Off Your Printer”.

4-2. Setting the Applications’ Print Condition

This section describes the settings for correct printing of garments.

4-2-1. Common Notice for All Applications

Color Mode / Color Space:

GT-3 Printer is RGB (Red Green Blue) printer. If you use Adobe, Corel applications, please note that some colors in CMYK

(Cyan Magenta Yellow Black) mode cannot be printed as expected because of the color matching process. We strongly

recommend that the artwork should be made in RGB mode and working space should be always "sRGB IEC61966-2.1".

GT-3 Series

4. Printing Directly from Applications

Print Layout:

Your printer has a large print area 14x 16 inches (35 x 40 cm), Any application has a rule to do the layout in printing, e.g.

Microsoft Internet Explore sets the artwork at the center top, Microsoft Power Point does at the center middle. The GT-3

Printer does not have Letter or A4 paper size. To avoid this issue, please set the paper size as 14x 16 inches (35 x 40 cm) and

do the layout manually by yourself. Use GT-3 FileOutput Printer Driver to see the final layout with GT File Viewer.

We recommend that GT-3 Printer should be your PC's default printer. See the last section of "3-3-3. Connection with USB 2.0

Cable: for Windows XP" or "3-3-5. Connection with USB 2.0 Cable: for Windows Vista / Windows 7".

How to make White data:

Printer Driver makes either White-only print data or Color-on-White-mask (under base) print data from one image data. When

you print colorful image by selecting "White-only", then the output is monochrome. Set RGB=254 white for white image.

RGB-255 (paper color) is transparent with no ink printed. When there are some spots in RGB=255 color in a photo, e.g. those

spots will never be printed. Use GT-3 FileOutput Printer Driver to see the final layout with GT File Viewer. As for the operations

for each application, refer to the following pages or application help.

Print Cancel:

Your printer does not start printing until you press the Print Button; The printer memory only holds one print job data at any

time.

<Important!>

Do not use canceling command from “Printer and Faxes (for Windows XP)” / “Printers (for Windows Vista)” / "Devices and

Printers (for Windows 7)" in “Control Panel”. Doing so causes an error and you may have to restart your printer.

Print AR3 files:

Use “GT-3 FileOutput” Printer Driver, which saves print data in AR3 format. With this you can see the detailed print conditions

and estimated ink cost. See “5. Printing AR3 Files.” for the details.

<Important!>

Do not use “Print to File” command in the applications’ Print window. File extension may be different.

<Note>

z You cannot print GT-541/GT-782 print data (ARP files) with GT-3.

z The settings of printer driver may be applied for one print; it depends on the application.

z The settings made with Control Panel of your PC sometimes may not be applied to the application. If so, make the

settings again in the menu of printer driver; these are applied to the actual settings.

transparent with no ink printed. RGB=0 black is transparent too when [ Print with Black ink ] is checked OFF, when black color

is expressed with the background T-shirt body color.

Transparent Color

You can select one transparent RGB color so that you can use red T-shirt color in the print data by changing R=255 GB=0 red

as transparent, instead of printing red colors with Magenta and Yellow ink combination.

(1) Check [ Transparent Color ] checkbox then the pull-down menu in the right will be available.

(2) Select one color from the pull-down menu (T-shirt simulation colors) or click [ Custom Color ] button and input RGB

values.

<Note>

Only one Custom Color is available at a time. This RGB values will not be added to the list.

Tolerance

Select the range from the transparent color to the normally-masked color. The gradation range becomes wider when the

value is bigger.

<Note>

Smooth gradation depends on the original image data. Better to do test print in advance.

Choke Width

Sometimes the mask White ink can be shown, which depends on the thickness of the T-shirt, humidity of the room, etc. You

can choke (cut out) the outline by one dot (1/600 dpi). Select the value. (The "double" dots are cut out when the resolution is

1200 dpi x 1200 dpi.)

<Note>

If the value is bigger, some thin lines (in the letters, photos, etc) might disappear. Better to do test print in advance.

4-3-12. Selecting the Color Processing for increasing the Vividness

When the image data is well-contrasted, adjust mainly with Saturation. When the image data is plain and dull, adjust mainly

with Contrast.

[ 0 ] no additional processing

around [10 ] no change in tone, a little brighter, good for photos

around [20 ] more vivid, for dull photo or RGB images

around [30 ] for light CMYK images

[40 ] maximum adjustment, for dull and plain CMYK images

The bigger value, more adjustment. When the image data is in CMYK mode, change the RGB mode and print with both

Saturation and Contrast around [ 30 ]. Sometimes the fine design may be flat with bigger [ Contrast ]. Better to do test print in

advance because sometimes the print data is unexpectedly changed.

<Note>

This menu is the same as GT-782, advanced Vivid Processing of GT-541. You can arrange the saturation (the strength of the

colors) and the contrast separately. GT-541 Vivid Processing is equal to GT-3 Contrast and you can adjust more precisely by

0-40. Vivid Processing 1 is identical to Contrast 10.

To get the optimum quality print result, you need to adjust the Platen height depending on the thickness of the T-shirt.

<Note>

z The clearance between the Clearance Sensor and the surface of the Print Heads should be app. 2 mm. If the clearance is

wider, the ink mist will spread inside the printer and the printing material, and may damage the sensors inside. If you print

with wider clearance (more than 2 mm) then check the inside of the printer and keep it clean. Replace the Maintenance

Parts by referring to "6-1. Replacing Consumables" and clean by "6-1-6. Cleaning the inside of the printer and restart" and

"6-1-7. Cleaning the Encoder Strip".

z If Platen height is too low, the result may be poor quality (e.g. a straight line becomes double). Adjust it properly by test

moving the platen in with Platen Button on the Control Panel. When you have to lower the Platen to avoid any material

which is thicker i.e. hems the hems, use Uni-Directional print (see "7-2-4. Changing the Print Direction"). You can set a

print data as Uni-Directional by the Printer Driver. See "4-3-14. Setting Print Direction as Uni-Directional".

Furthermore, do not drink the liquids: Ink, Wash Liquid, Maintenance Solution, Pretreatment or waste liquid under

any circumstances, as they can cause vomiting and diarrhea.

Keep the liquids out of the reach of children.

4-6-1. Applying the Pretreatment

Pretreatment must be applied on a T-shirts to keep the White ink on the surface of a T-shirt. Wear gloves to keep

Pretreatment from the skin.

<Note>

z Use a heat press and "thin and flat" glass cloth sheet or fluorine coated sheet (Teflon Sheet) to cure the Pretreatment.

The surface must be as flat as possible in curing. If you use an oven, the fibers may not lay down flat causing low print

quality.

z Place glass cloth sheet or fluorine coated sheet (Teflon Sheet) to cover the pressed surface so that the T-shirt can be flat

and even.

z Water drops on the Pretreatment-cured surface turn stains, because the white ink can sink into the T-shirt fibers. Do not

wet the cured surface. Do not leave a Pretreatment-cured T-shirt in a humid space.

z Be aware of the temperature of the heat press in curing the Pretreatment. Temperature easily drops by continual curing.

If the temperature is low, the Pretreatment can not make ink barrier on the surface of the T-shirt and the White ink may

easily sink into the fibers and can not produce enough white.

z Better to use an Urethane mat (continuous foam) to release more steam while curing.

z If CMYK inks are printed on a Pre-treatment applied T-shirt, ink may washed off. Do not apply Pretreatment when you

print without using White ink.

z Pretreatment on some T-shirts may be seen easier after applied and cured. Wash lightly with water. Some dyes may be

decolorized by Pretreatment, we recommend you test the garment before printing.

z Pretreatment mist may spread out when you use a spray and/or pretreatment applicator. Ventilate your room in operation.

Wear a face mask or goggles as necessary.

4-6-2. Making One Print

GT-3 receives the next print data from PC in printing. Just before you press the Print Button, confirm the Job Comment (or file

name) and the counter on the display of the Control Panel.

(1) Make sure the Print Button has been turned on, which indicates your printer has received the print data successfully.

(2) Make sure that the Platen is ejected and the printed material is set properly. If not, press the Platen Button.

(3) Make sure the Platen Height, The clearance between the Clearance Sensor and the surface of the Print Heads should

be app. 2 mm. Before / after you print on thicker material, use Platen Button to move the Platen to confirm the clearance.

(4) Confirm the Job Comment on the Display shows the correct print job details. Check the counter whether it is 000 (new) or

not (previous).

(5) Press the Print Button to start printing operation.

When the printing is completed, the Platen is ejected and an audible indication is given.

If printing is to be stopped before it is finished, press Stop Button to stop the operation. Then press Platen Button to eject

the Platen.

<Note>

z By pressing the Print Button, your printer automatically starts cleaning the Print Head every 24 prints (default) or every

numbers of prints you have set (see "7-2-5. Changing the Auto Head Cleaning Setting”), or after your printer has not

been used for

more than two hours. In this case, wait until the cleaning completes (takes about 20 seconds), and

then printing will automatically start.

z Keep away from the moving platen.

z If the Platen is not at the appropriate position when the Print Button is pressed, it automatically adjusts the position to

start printing. Press the Print Button again to start printing after the Platen is available

z Do not open unlock or open the Cover during printing. If you do the power is turned off for safety reasons.

4-6-3. Printing More than One Print Using the Same Print Data

(2) Press the Print Button to start printing. The counter indicates how many images are printed.

GT-3 Series

4. Printing Directly from Applications

4-7. Removing the T-shirt from the Platen

(1) Hold the shirt slightly to allow are to get between the shirt and the platen.

(2) Hold both shoulders of the T-shirt, and then pull it out straight from the Platen. Hold the T-shirt by the printed area on your

side, which is easier to deal with the wet T-shirt safe.

<Note>

Be careful not to get "wet" ink on your hands or printed material. Wash your hands or clothes with soap if stained. You

cannot wash away the stained ink on the material because the ink may be absorbed into the fiber.

4-8. Curing the Ink onto the T-shirt

To cure the ink onto the T-shirt, a heat press is handy and convenient in time and temperature control. The condition to cure

ink is 180°C (356°F) in 35 seconds. When you print with White ink, use release paper. Use conveyor oven (tunnel) for mass

production; it takes longer but the washability is a little improved, and the feel of the surface is softer than cured by a heat

press. The condition is 160°C (320°F) at the printed surface in 3 minutes and 30 seconds by the conveyor oven shown

below. Follow the instruction manual that comes with your Heat Press and conveyor oven, and be sure to confirm the actual

conditions (temperature inside and the actual curing test) before you start production.

<Note>

z The actual conditions of the heat press and conveyor oven may be far from your expectations. The temperature in the

tunnel part may not be even. To keep the washability, calibrate your conveyor oven and do test print.

z The colors may be faded by washing and rubbing when the curing conditions is not appropriate.

z The hat press and the oven should be used in a well ventilated environment. When curing the White ink, better to use an

oven with much ink on the surface. The surface of an T-shirt by an oven feels more natural and by an heat press more flat

and glittering.

z After using the Heat Press, always confirm if the ink is completely dry and cured.

z Make sure the surface of the Heat Press and glass cloth sheet or fluorine coated sheet (Teflon Sheet) are clean before

and after curing the T-shirts.

z Depending on the material, curing conduction may vary, be sure to test new materials before you use. Pretreated garment

is easier to be burnt than the normal garment.

z Printed colors may transfer when a printed surface rubs on a white or light-colored synthetic leather made of PVC

(polyvinyl chloride). When printing CMYK-only garments, the CMYK ink may transfer to the White-only printed garment

when they rub against each other. In those cases, clean the stains with a soft cloth or toothbrush with a household cleaner

or alcohol.

7-2-1. Procedure for Solving the Print Quality Problems

Follow the procedure (Step 1 to 7) below until the print quality problem is solved.

<Note>

The following steps are shown with CMYK Print Heads and do the same in case of White Print Heads.

Step 1: Confirm the amount of remaining Ink in the Ink Cartridge and execute Normal Cleaning.

Head Cleaning, with flushing fresh ink, can solve most of print quality problems. Check the nozzles by test printing of Nozzle

Check Pattern (see "7-2-3. Checking Print Quality with Nozzle Check Pattern ") first and execute Normal Cleaning to the Print

Head concerned (see “7-2-2. Cleaning the Print Heads / Using the Head Cleaning Button”) Repeat the Normal Cleaning a

few times. and check again by printing Nozzle Check Pattern. If the problem is not solved, go on to the next step.

<Note>

z It is very important the machine is used in an environment as specified. Use a humidifier to keep the humidity up to 35% to

keep print quality.

z Your printer automatically cleans its Print Heads every 24 prints; however more frequent Print Heads cleaning may need

to be done depending on the environment. In this case, change the Auto Head Cleaning frequency (see “7-2-5. Changing

the Auto Cleaning Setting”).

Step 2: Replace Wiper Cleaners and clean around the Print Heads.

The Wiper Cleaner absorbs waste ink carried by the Wiper Blade. If Wiper Cleaner cannot absorb waste ink any more, the

dirty Wiper Blade wipes the Print Head Nozzles again and this causes misfiring or damage the Print Head. Replace the Wiper

Cleaner regularly and clean the Wiper Blades and caps. Check if it is too dirty to wipe off the waste ink when you cannot solve

mis-firing by Nozzle Cleaning.

How to Check:

(1) See "6-1-2. Replacing the Wiper Cleaner and Cleaning the Caps / Wipers" and select [ Maintenance ] > [ Maintenance

Parts Exchange ] of the menu.

(2) Replace Wiper Cleaners as well as cleaning Wiper Blades and Caps. replace Flushing Plate Sponge and Flushing Plate

Felt too because the dirty surface of the Flushing Plate felt may give dame to the Print Head Nozzles. See "6-1-3.

Replacing Flushing Plate Sponge and Flushing Plate Felt".

(3) Confirm the inside of the printer and clean if necessary. See "Cleaning the inside of the printer and restart".

<Note>

Do not tilt the Wiper Cleaner Cassette; ink may get on your hands or clothing.

(4) Check the Wiper Cleaner, and if it is heavily soiled, replace it using the Cap Cleaning Kit (see “6-1-2. Replacing the Wiper

Cleaner and Cleaning the Caps / Wipers”). If the Wiper Cleaner is not heavily soiled, go on to the next step.

Step 3: Check the ink tubes and execute Powerful Cleaning.

Open the Front Cover with both hands until it is locked with the stopper and check the ink tube inside if there is any "empty" air

space longer than 5 mm. If so, push the Stop Lever to release the lock when you close the Front Cover with both hands and

turn ON the printer, execute Powerful Cleaning to fill the tube with ink. Confirm by turning OFF the printer and open the Front

Cover. If not enough or the "empty" air is large, execute Initial Cleaning in [ Maintenance ] menu. to replace the old ink.

<Note>

As for White Ink, you do not have to load Maintenance Solution, go on the Initial Cleaning with White Ink Cartridge with

"Maintenance Cartridge" is indicated on the Display, and press the Stop Button to discontinue the operation after 10 seconds.

If the problem is not solved, proceed to the next step.

GT-3 Series

7. Troubleshooting

107

Step 4: Confirm the "conditions" of mis-firing.

(1) Print the Nozzle Check Pattern, and check which Print Head has the problem (see "7-2-3. Checking Print Quality with

Nozzle Check Pattern ").

(2) If the missing positions (nozzles) are fixed, then go to Step 5. If the missing position shift every time you print Nozzle

Check Pattern, then maybe some tiny air bubbles are in the Print Head Nozzles. Execute Powerful Cleaning and confirm

with Nozzle Check Pattern. (See “7-2-2. Cleaning the Print Heads”).

<Note>

If you have time, leave the printer unused for 15- 20 minutes then the tiny air may be settled.

If you find mis-firing when you print rather large image though Nozzle Check Pattern is OK after Normal Cleaning, go to

Step 6.

Step 5: Clean the Print Head Nozzles.

(1) Clean the Print Head Nozzle using the Nozzle Cleaning Kit (see “7-2-6. Cleaning the Print Head Nozzles”).

<Note> Use new Clean Applicators to clean the Nozzles.

(2) Execute Powerful Cleaning to remove air bubbles inside the Nozzles. Print Nozzle Check Pattern to confirm the print

quality. If the problem is not solved after Head Cleaning and print test, go to Step 6.

<Note>

Make sure to execute Powerful (or Initial) Cleaning after Nozzle Cleaning.

If the problem is not solved, go to the next step.

Step 6: Contact Brother Customer Service or your dealer.

Please tell your service how the issue has started, the present conditions, the troubleshooting that you have done, etc. If you

are asked to replace the Print Head by yourself, see “7-2-7. Replacing the Print Head” for the procedure.

7-2-4. Changing the Print Direction

When there are large gaps between the Print Heads and printed medium, or when printing on very high absorbent material,

horizontal stripes and color graining can appear on the printed image. You can solve this problem using one-way

"Uni-Directional " print. If you adjust to a larger gap then we recommend this mode is used. Keep the clearance between the

Clearance Sensor and the surface of the Print Heads should be app. 2 mm by adjusting the Platen Height.

If you already know that a print data will be printed in uni-directional printing before you print, you can set with the Printer Driver.

This setting is available when the printer’s setting is [ Auto ]. See “4-3. Setting the Printer Driver Condition” and “4-3-14. Setting

Print Direction as Uni-Directional”.

(1) Select [ Print Direction ] with Up/Down Button from the menu and press the OK Button.

(2) Select [ Always Uni- ] when you print one-way "Uni-Directional" printing. Select [ Always Bi- ] when you print by-directional

even if the Printer Driver setting is Uni-Directional Printing with Up/Down Button and then press OK Button. This setting is

always available until you change the setting.

06e0031Y

<Note>

z Uni-Direction Icon is on the Display of the Control Panel.
