machine to weight the amount of spray, with a scale, after applying the Pre-Treatment liquid on a T-shirt!
> For example, on a Schulze PTM, you should enter a lenght of 36 cm and the full width of 4 nozzles will be
40 cm! And then, calibrate the PT machine to spray 30 g on the garment!

DAILY AGITATION OF WHITE INK
POUCH REPLACEMENT - VERY IMPORTANT PROCESS!
Open the cartridge's lid on a flat 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
flat 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 again !
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.
Perform the procedure shown below if the message "Remove the white ink
cartridge and shake it" is displayed before starting printing operation.
Take out the white ink cartridge from
the printer.
Shake the cartridge horizontaly 100
times side by side to stir the white ink.
At a ink level of approximately 15 cm,
shake the cartridge with cover open and
with the ink pouch slightly unwinded, to
make the ink easier to stir.

To adjust the platen height, loosen the Platen Fixing
Lever and move the Platen Height Adjustment Lever
. to a lower position.
Re-tighten the Platen Fixing Lever if you are happy with
new distance. Flaten 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 more, remove 1 or 2 col-
lars, loosen the knob and push down the platen bearing
by 1 or 2 steps.
Reattach everything and tighten again the Platen Fixing Lever
>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!
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.

> Don't forget to bring back the platen to the Aposition after printing on thicker material!

WEEKLY MAINTENANCE
Suction Cap & Exhaust Cleaning
!
TO BE DONE EVERY WEEK
To achieve a good weekly maintenance you will have to do the following actions:
The black silicon lips of the two cappings should be cleaned with the NEW Cleaning
Stick Tdipped in Cleaning Solution.
It is necessary to remove the build-up of the remaining ink staying on the edges of
the cappings. It will prevent air leakage and keep the good suction of the pumps!
Be careful not to touch the foam! Keep it flat!

WEEKLY MAINTENANCE
The four extrusion lances [see in the blue circle] and the 2 holes
sitting on the side of the capping at the Exhaust position
need also to be cleaned and free of dried ink.
Always clean first the hole at the front and go backward
while cleaning the lances and finish carefully by the last hole!
