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 drip-
ping onto the stencil during print carriage initialisation or auto stencil loading.
The drip tray retracted sensor is used by software to check that the pneumatic actuator has retrac-
ted the drip tray before lowering the squeegees.
