The squeegee drip tray mechanism is secured below the print carriage and behind the squeegee
mechanism. The drip tray’s pneumatic actuator extends the drip tray below the squeegees to pre-
vent print medium from dripping onto the stencil during print carriage initialisation or auto stencil
loading. Magnets hold the drip tray in place and can easily be unhooked for easy cleaning.
There are two sizes of drip tray:
●
460mm
●
360mm

8.1 OVERVIEW
128 TECHNICAL REFERENCE MANUAL DEK TQ 04/2021
To prevent a collision with the drip tray,a short drip tray (360mm) should be used in conjunction
with a stencil size of 6320mm
(24.409") or less.
The drip tray retracted sensor is used by software to check that the pneumatic actuator has retrac-
ted the drip tray fully before lowering the squeegees.
The rubber bumper stop prevents a collision with the stencil load mechanism when retracting.
