Self Adjusting Paste
Deflectors (SAPD)
SAPD use a pair of deflectors which each have a piston that is spring loaded.
Once screwed in place, the deflectors self adjust with wear. These deflectors
are only available for 60 degree squeegees.
In the graphic below the differences between the standard paste deflectors (top
image) and the self adjusting type (bottom image) are evident.

Squeegee Drip
Tray
Figure 9-2 Squeegee Drip Tray Overview
The squeegee drip tray mechanism secures to the underneath of the print
carriage. The drip tray pneumatic actuator extends the drip tray below the
squeegees to prevent print medium from dripping onto the stencil during print
carriage initialisation or auto stencil loading.
The squeegee drip tray mechanism is also used to accommodate the auto
screen loader mechanism, refer to the Adjustable Screen Mount (ASM) or Cast
C Chase Module chapters for more information.
The drip tray retracted sensor is used by software to check that the pneumatic
actuator has retracted the drip tray before lowering the squeegees.
NOTE
With the squeegee drip tray and the screen depth adjuster fitted, the ASM must
be set to 29 inches and cannot accommodate smaller stencil sizes.
