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 printhead is provided having an elongate support having a plurality of internal webs protruding from a base section to define a plurality of parallel fluid supply channels, a shim supported by the support and defining a plurality of rows of openings through which fluid from respective supply channels is supplied, and a plurality of elongate printhead modules supported serially on the shim. Each module defines a plurality of fluid supply passages through which fluid passes to fluid ejection nozzles from respective rows of the openings. Either end of each module defines complementary formations such that adjacent modules nest together.
