1 GENERAL INFORMATION

The printer should only be used by operators who are appropriately trained in its safe operation.

The printer is not suitable for use in places where children are present.

The GTXpro should always be left with power ON, also when it is not in use.

Power is needed to perform the recirculation of the white ink every day. This process does not consume ink.

If the GTXpro is turned OFF for a long time it might get damaged.

Only pull the plug in an emer-

gency or when requested by a

display message!



Center the roll between the edges of the plates.

Then fasten the thumbscrews.



Turn the brake knob right side counter-clockwise

until it stops to release the brake completely.



Repeat the operation on the left side.



A: Insert the film carefully and in an even way.

B: The lock lever must be down to be open.



Align the film straight on the print table. If you

use a 40cm roll, remove the screws from the

side guides and screw them back into the

outer holes.



Then slightly, with one finger, turn each knob

clockwise till you feel a slight resistance.

It is best to set the buttons identically.



HELPFUL: Attach a spring balance to the film and

slowly unroll it a little. The resistance value should

not exceed 100 gr.
