Abstract: A modular printer includes: a media support defining a media feed path; and a plurality of pagewide printing units spaced apart along a media feed direction of the media feed path. Each printing unit includes: a maintenance chassis fixedly positioned over the media feed path; and a print bar chassis seated on the maintenance chassis, the print bar chassis supporting one or more print modules extending across a width of the media feed path. A lift mechanism raises and lowers the print bar chassis relative to the maintenance chassis, with each print bar chassis being independently liftable from a printing position to a maintenance position. A footprint of each printing unit in both the printing and maintenance positions is defined by a perimeter of the maintenance chassis.

Abstract: A pagewide printing unit for mounting over a media feed path and printing onto media. The printing unit includes: a print module having a printhead; a maintenance module having a fixed frame supporting a capper and a wiper, the print module being movable relative to the fixed frame; and a lift mechanism for raising and lowering the print module relative to the fixed frame between a maintenance position a printing position.
