The printer can
operate outside
of these ranges
however it may
use more ink
or take longer
to print.
Mandatory Temperature & Humidity Requirements:
ENVIRONMENTAL CONDITIONS
Help keep your printer in warranty while saving on ink, consumables, and time
You can use an empty distilled water jug and marker to measure out the amount of Pre-Treatment by drawing a
line on the jug - then fill to that line twice with distilled water, adding the contents into the Ready to Use container.
To check Go to the menu: Maintenance > Temperature/Humidity info >
PRE-TREATMENT RATIO
PRE-TREATMENT QUANTITY on T-SHIRTS
The correct Pre-treat volume for a garment should be determined by a garment's absorbency rate in conjunction with
using the highlight check pattern to help determine driver ink settings.
Don’t forget that you have to define a surface of 35 x 40 cm (14 x 16 inches) with your Pre-Treatment machine and
weigh with a scale after applying the Pre-Treatment liquid on a T-shirt.
If the temperature is too cold, the printer will automatically switch to Low-Temp Mode and reduce the speed!
Damages resulting from being too far outside of the environmental requirements may not be covered by warranty

If the Temperature and Humidity is not enough, then add an Evaporative Humidier
This mixing ratio might vary due to the type of garment which is used.

VERY IMPORTANT
The Brother GTX should ALWAYS be left with the Power ON
NEVER shut OFF the printer unless instructed to by the display panel. Power
is required to perform the white Ink recirculation from time to time.
In the event that the 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.

You can also use Parchment paper when curing the Pre-treatment in order to minimise the need to clean off
the covers and to avoid issues with bers standing up on the garment

Perform the procedure shown below if the message "Remove the white ink cartridge
and shake it" is displayed before starting operation.
Remove the white ink cartridge
from the printer. Shake the
cartridge horizontally 100 times
side to side to stir the white ink.
It's extremely important to understand how to agitate the ink daily - it's just as important to
understand when to perform both the agitation and press on the panel after reinserting
the ink. If you are not printing for a few days, you should avoid doing this process. There
are some rules to follow as to when you should agitate the ink and press . The printer will
automatically perform a White Ink Relling to refresh the ink in the lines and head after you
reinsert the ink cartridge and press .
DAILY AGITATION OF WHITE INK
When to Agitate the White Ink and Press "OK"
When the ink pouch becomes approximately
15cm in length, shake the cartridge with its
cover open. This will slightly unwind the ink
pouch and make the ink easier to stir.
Repeat the same process on the other
white ink cartridge.

Open the cartridge's lid on a at surface and remove the empty pouch.
Carefully unpack a new ink pouch from its shipping carton. Avoid wrinkling the pouch.
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 gutters of the of the cartridge lid, and mount in
position inside the metal spring by pulling it with your hand.
(If the edge of the ink pouch is bent or undulating signicantly, atten and straighten it with your hand)
Align the pouch so that it sits in the middle of the cartridge. Close the lid and verify that
the spring is rolling to the front. Raise the cartridge to a 45°angle and push on the two
upper metallic latches to add more tension to the ink pouch.
Attach a shelf life sticker included with the ink pouch onto the front of the cartridge.
If you are storing white ink for more than one week without use, then you need to
ip over the ink carton weekly to prevent the ink pigments from settling in the pouch.
Agitate the new white ink side to side while
still in the carton before loading it into the
cartridge. New ink should be agitated 100
times on each side. Following this process
will save time as both ink pouches are
agitated at the same time in the carton.
POUCH REPLACEMENT - VERY IMPORTANT
If you know you're going to print a large order or are low on ink, ensure you have
spare ink on hand. Running the printer dry can damage the unit and keep you from
finishing a job which can lead to costly repairs!

you need to to decrease the gap further, remove 1 or 2
collars, loosen the knob and push down the platen
bearing by 1 or 2 steps.

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 LONGEVITY OF YOUR PRINTER.
if you need to print above the hem and seams, choose UNI-directional printing to keep quality.
Don't forget to return the platen to the Aposition after printing on thicker material.
Always leave the knob tight after changing position.
ADJUSTING THE HEIGHT OF THE PLATEN
To achieve optimum printing quality when a thicker textile is used, adjust the platen
height relative to the thickness of the textile.
