ADJUSTING THE HEIGHT OF THE PLATEN

GTX MAINTENANCE OVERVIEW

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. Re-attach everything and tighten again the Platen Fixing Lever

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 when you have

nished to print on thicker material!

> HOW TO DO A NOZZLE TEST ?

DAILY MAINTENANCE

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

> WEEKLY MAINTENANCE PROCEDURES

The black silicon lips of the two cappings should be cleaned with the Cleaning Stick R

dipped in Cleaning Solution.

It is necessary to remove the built-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 at!

The four extrusion lances (see in the blue circle…) and the hole

sitting on the side of the capping at the Exhaust position need

also to be cleaned and free of dried ink.

Always clean rst the hole at the front and go backward while

cleaning the lances !
