ENVIRONMENTAL CONDITIONS

Ideal Operating Temperature & Humidity

Go to the menu: Maintenance –> Temperature/Humidity Info

> If temperature is too cold, printer will switch automatically to Low-Temp Mode and reduce output.
> If humidity too low, please install a HUMIDIFIER.
> Min & Max Temperature & Humidity ranges are ideal and we recommend running your GTXpro at a higher
number than minimum to reduce additional cleanings.

PRE-TREATMENT RATIO & QUANTITY

Determining Pretreat Quantity

Pretreat solution quantity will vary based on thickness of the garment. Use the chart below as a guideline.

HEAT PRESS SETTINGS FOR PRETREAT CURING

> Placing silicone based parchment paper over the pretreated garment while heat pressing can mitigate dried pretreat buildup on the non-stick covers. Clean the non-stick covers on the heat press with a scrap t-shirt or cloth after every 5 t-shirts if not using silicone based parchment paper.

HEAT PRESS SETTINGS FOR INK CURING

> Check the REAL temperature of the heat press with a probe or with strips to ensure that your garments are properly cured for washability.

CONVEYOR DRYER SETTINGS FOR INK CURING

> Check the REAL temperature of the heat press with a probe or with strips to ensure that your garments are properly cured for washability.

NEVER POWER OFF THE PRINTER

VERY IMPORTANT

The Brother GTXpro should ALWAYS be left with the Power ON. NEVER shut OFF the printer except if requested by the display message only. Power is needed to perform the needed circulation of the white ink and auto maintenance every day.

In the event that power goes out or your printer has an error during printing, push the Carriage back all the way to the left to dock it and use the Fixing Pin to lock it in place

DAILY AGITATION OF WHITE INK

Perform the procedure shown below if the message “Remove the white ink cartridge and shake it” is displayed before starting the printing process.

Remove the white ink cartridge from the printer. Shake the cartridge horizontally 100 times side to side to agitate the white ink. When the ink depletes to the level of approximately 6 inches (15 cm), shake the cartridge with the cover open and the ink pouch unwound which will make the ink easier to agitate.

Repeat the same process with the other white ink cartridge. Once agitation is complete and cartridges have been re-inserted, press [Menu/OK] on the control panel.

Daily White Ink Agitation

INK POUCH REPLACEMENT

Open the cartridge’s lid on a flat surface and remove the empty pouch. Carefully unpack a new ink pouch from its shipping carton.

Push the green tip end of the ink pouch into the cartridge until it clicks into place. Straighten the ink pouch to align it with the gutter of the lid of cartridge, and mount in position inside the metal spring by pulling it with your hand. If the edge of the ink pouch is bent or wrinkled, smooth it out with your hands to remove wrinkles.

Place the pouch in horizontal alignment with the cartridge. Ensure lines of the catridge and pouch are in alignment.

Close the lid, and verify the spring is rolling to the front. If spring does not roll, smooth out wrinkles and try again. Place the cartridge at a 45° angle and push on the 2 upper metallic latches to add a bit more tension on the ink pouch. Double-check that you have not generated more wrinkles.

Clean the outside of the green tip end that goes in contact with needle inside printer. Attach a shelf life sticker included with ink pouch onto the front of the cartridge.

> If you are not trying to avoid wrinkles like explained above, you could get the errors 2084 & 2085 displaying: “Winding-up Failure”

Ink Pouch Replacement

BEST PRACTICE FOR PRINTING – A MUST!

> Always keep the closest distance between the printheads and the surface of the garment. It is very important for the long life of your printer.

ADJUSTING THE HEIGHT OF THE PLATEN

To ensure optimal print quality when a thicker textile is used, you need to adjust the platen’s height in relation to the thickness of the textile.

To adjust the platen height, loosen the Platen Fixing Lever (1) and move the Platen Height Adjustment Lever (2) to a lower position.

Re-tighten the Platen Fixing Lever (1) if you are happy with the new height. Smooth out all wrinkles on fabric to be printed on. To check if new textile is not detected by the sensor, push the double arrow platen feed button and repeat the process if needed. If you need the platen to go down further than the lowest setting, remove 1 or 2 collars, loosen the knob (3) and push down the platen bearing by 1 or 2 steps. Reattach everything and tighten the Platen Fixing Lever (1).

> Don’t forget to adjust the platen lever to position A after printing on thicker material.
> Always tighten knob (3) after changing position. Do not overtighten screw as it can become stripped.
> If you have to print above hem and seams, go for UNI-directional printing to keep quality.

“PLATEN TOO LOW” SENSORS

DAILY MAINTENANCE: Nozzle Check

In order to check the status of the nozzles in the print heads, a Nozzle Check must be performed for White and CMYK. This should be done every day to ensure optimal performance.

How to perform a CMYK Nozzle Check?

Always place the Platen at level A

Menu –> Test Print –> Nozzle Check CMYK

How to perform a WHITE Nozzle Check?

Menu –> Test Print –> Nozzle Check White

> Inspect the printed Nozzle Check patterns for missing nozzle lines indicating a non-firing nozzle. If not all nozzles are firing, start a Head Cleaning to open the closed nozzles.

Printing a Nozzle Check

PRINT HEAD CLEANING

Print Head Cleanings are needed if nozzles are missing on a Nozzle Check. They will help clear the print head nozzles if they are blocked. Missing Nozzles are defined by a test print pattern missing horizontal pins (that represent each of the nozzles of the print head) being closed up with debris and therefore not showing up. When nozzles/pins are missing you will want to perform one of the cleanings indicated below.

How do I perform a Print Head Cleaning?

If only a few nozzles are missing (See fig. 1), do a Regular / Powerful Cleaning and select applicable print heads. (Less than 5 nozzles missing will not be a big issue, if they are not together)

Menu –> Head Cleaning –> Normal / Powerful Cleaning

If more than 10 nozzles are missing (See fig. 2), do a Powerful / Super Cleaning and select applicable print heads.

Menu –> Head Cleaning –> Powerful / Super Cleaning

> Perform a new Nozzle Check after Head Cleaning to check the result and redo the cleaning up to 3 times. Ensure all other maintenance has been performed such as cleaning the cap and wiper blade and see that the wiper cassette is fresh and still has moisture. If there is no improvement by the 4th time, please contact support.

DEFLECTION & FLASH FIRING

Deflection appears as odd bunched up or gapped lines where the horizontal bars will appear blurred and staggered. When this is present you will want to perform 2-3 Flash Fire Cleanings.

After performing a Flash Fire Cleaning 2-3 times, perform another Nozzle Check to test the results.

Menu –> Head Cleaning –> Flash Cleaning

> If this does not resolve the matter, please contact Tech Support.

WEEKLY MAINTENANCE

To achieve successful weekly maintenance you will have to do the following actions:

• Suction Cap Cleaning
• Exhaust Cap Cleaning
• Wiper Cleaning
• Nozzle Guard Cleaning
• Visual Inspection

> You will have 15 minutes to complete any pending items for the maintenance process. Prepare to complete all items within the allotted time.

Menu –> Maintenance –> Maintenance Part Clean/Replace

Suction Cap Cleaning

The black silicone lips of the two suction caps should be cleaned with the Cleaning Stick T dipped in Cleaning Solution.

It is necessary to remove the build-up of excess ink located on the edges of the caps. It will prevent air leakage and maintain optimal suction of the pumps. Be careful not to touch the foam. Keep it flat.

Exhaust Cap & Lances

The four extrusion lances and the 2 holes [see in the blue circle] are located adjacent to the suction caps at the Exhaust position. They need to be cleaned and free of dried ink. Always clean the first hole at the front and go backward while cleaning the lances, carefully finishing with the last hole.

Wiper Cleaning

Both white plastic wipers [White & CMYK] should be cleaned on both sides and tops with the Cleaning Stick T dipped in Cleaning Solution.

Use the tip of the Cleaning Stick T to clean under the teeth of the wiper holder and remove the dried ink.

Be sure to use the Cleaning Stick T separately for white ink and color ink.

If a more thorough cleaning is required, refer to removal of wiper in the instruction manual for a detailed cleaning.

Nozzle Guard Cleaning

Wipe clean the 2 nozzle guards (1) & (2) with the Clean Stick R dipped in Cleaning Solution. Make sure to clean and remove any dried ink in the nozzle guard port holes. Clean the metallic parts (4) & (5) of the printhead in the same way.

A very important place to clean is area (6) between the nozzle guard and nozzle plate.

Be sure NOT to touch the nozzle surface (3) at all.

> Manually move the carriage to such a position that you can perform the cleaning with ease.
