Pre-treatment Ratio & Quantity
You must use distilled water
Mix Ratio should be 1:1
When to change Pre-treat Mixture 1:1 to 1:2
When to change pre-treat mixture from
1. Certain garment colours may react negativity to a 1:1 ratio and may require the
mixture ratio of 2:1.
2. If applying a 1:1 mixture to a garment and after pressing it shows a strong
stain regardless of fluid speed you may need to change the mixture ratio. When
using a 2:1 mix ratio you may need to increase the amount of white ink for a
more vibrant print compared to a shirt pre-treated at 1:1.
3. You will want to mix a batch of pre-treat with 2 parts distilled water and 1 part
pre-treat ratio.
4. For example, you would mix 2 cups of distilled water to 1 cup of pre-treatment
to obtain a 2:1 ratio.

Pouch Replacement - Very Important Process! R
Open the cartridge's lid on a fat surface and remove the empty pouch. Unpack
carefully 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 undulating significantly, make it straight
and fat with your hand to avoid wrinkles.
Place the pouch in a straight alignment with the cartridge. Align lines with each
other!
Close the lid, verify if the spring is rolling to the front. Place the cartridge at
around 45° 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 some wrinkles

cartridge.

Best Practice for Printing!
Always keep the closest distance between the PRINT HEADS ant the surface of
the garment! It’s very important for the long life of your printer!
Adjusting the Height of the Platen
To provide an optimum printing image quality when a thicker textile is used,
you need to adjust the platen's height related to the thickness of the textile.
To adjust the platen height, loosen the Platen Fixing Lever and move the 1
Platen Height Adjustment Lever 2 to a lower position.
Re-tighten the Platen Fixing Lever if you are happy with new distance. Flatten
down all the wrinkles of the fabric. To check if new textile is not detected by
the sensor, push the button and repeat the process if needed! If you need to
go down further, remove 1 or 2 collars, loosen the knob 3 and push down the
platen bearing by 1 or 2 steps.
Reattach everything and tighten again the Platen Fixing Lever
Don't forget to bring back the platen to the A position after printing on thicker
material!
Always leave the knob 3 tighten after changing position!
If you have to print above the hem and seams, go for UNI-directional printing
to keep quality!

Suction Cap & Exhaust Cleaning
The black Teflon lips of the two capping’s should be cleaned with the NEW
Cleaning Stick T dipped in Cleaning Solution.
It is necessary to remove the build-up of the remaining ink staying on the
edges of the capping’s. It will prevent air leakage and keep the good suction of
the pumps! Be careful not to touch the foam! Keep it fat!
