Abstract:
1. A printer comprising: a support structure; a feed arrangement positioned on the support structure, the feed arrangement including a pick-up assembly having a first array of spaced apart nozzles configured to direct air onto a top surface of a topmost sheet of a stack of print media, and a second array of spaced apart nozzles configured to suck air away from a top surface of the topmost sheet; a swing arm pivotally affixed at one end to the feed arrangement, and supporting at another end the pick-up assembly, the swing arm providing rotational movement to the pick-up assembly a pair of rollers configured to engage with said topmost sheet; a printing station configured to print ink upon said topmost sheet; and an air displacement mechanism connected to the first and second array nozzles to displace air out of the first array of nozzles and suck air into the second array of nozzles, wherein said swing arm rotates the pick-up assembly between a first and second position, the first position being a position at which air is displaced out of the first array of nozzles, and the second position being a position in close vicinity to the pair of rollers and at which air is neither displaced out of the first array of nozzles nor sucked into the second array of nozzles, and each nozzle includes an elastomeric cup mounted to the pick-up assembly via a spring.
