ABSTRACT:
A dispensing apparatus includes a frame, a support coupled to the frame, a gantry coupled to the frame, a first dispensing unit coupled to the gantry, a second dispensing unit coupled to the gantry, and an imaging system coupled to one of the frame and the gantry. The imaging system may be configured to capture at least one image of a first pattern and a second pattern, with the second pattern being identical to the first pattern. The dispensing apparatus further includes a controller configured to verify whether the first pattern and the second pattern are properly positioned on the support with respect to one another based on the at least one captured image to permit simultaneous dispense operations of the first dispensing unit on the first pattern and the second dispensing unit on the second pattern. Other embodiments and methods of dispensing are further disclosed.
