Abstract: A printing unit includes: a unit chassis and a pair of opposed inkjet modules mounted in tandem on the unit chassis in forward and reverse orientations, each inkjet module having one respective printhead and at least one of: a capper and a wiper. Each printhead includes first and second rows of print chips mounted on a unitary surface of a respective ink manifold, the first and second rows of print chips having a plurality of print chips butted end-on-end along a length of the printhead. The printheads are wholly aligned with respect to a media feed direction for printing in four ink colors from the pair of printheads.
