Abstract: A method and apparatus for forming a high resolution LED array. A plurality of LED chips are provided to form the LED array. Each LED chip has an electrode that is inward biased at each end of the chip by a predetermined amount. The size of each LED chip is removed by reducing, at each end of each chip, an amount of chip material substantially equal to the predetermined amount. The array is formed by placing each chip end to end with a gap between each chip, wherein the gap is suitably large for placement accuracies and a consistent pitch of 21.2 mu m is maintained between each LED on each chip.

Abstract: A maintenance assembly (129) for cleaning a plurality of printheads (125,126) in a printing machine comprises two or more cleaning members (150), each of the cleaning members (150) sized and positioned to clean at least one but less than all of the plurality of printheads (125,126) when in a cleaning position. A drive mechanism (174) associated with each of the two or more cleaning members (150) is configured to selectively move an associated cleaning member to and from the cleaning position and a retracted position. The cleaning members (150) are supported on a frame with a mechanism (130) provided for translating the frame into position juxtaposed with the plurality of printheads and a further mechanism to swipe the cleaning members across the printheads. The maintenance assembly (129) is operable to clean only selected printheads in a single operation.
