Abstract: A modular inkjet printhead includes a plurality of printhead modules arranged end on end in a row. Each printhead module includes: a substrate having a plurality of ink supply channels; a plurality of print chips mounted on the substrate, each print chip receiving ink from a respective ink supply channel; and a plurality of fingers extending longitudinally from opposite ends of each printhead module, each finger comprising at least a portion of a respective print chip. The fingers of neighboring printhead modules are interdigitated such that print chips of neighboring printhead modules overlap and the portion of the print chip contained in a respective finger is positioned towards one lateral edge of the finger.

Abstract: A printing device includes: an inkjet printhead; a lift mechanism for raising and lowering the printhead through a lift path; and a pivotally movable spit flap positioned in the lift path. The spit flap is configured to swing away from the lift path when the printhead contacts the spit flap during lowering of the printhead.

Abstract: An ink delivery system for an inkjet printer includes: (a) an ink delivery module for supplying and receiving ink in a circulating fluidic loop having positive and negative pressure ink lines; (b) print modules interconnected between the positive pressure ink line and the negative pressure ink line. The ink delivery module has regulator pumps for gross control of ink pressure in the print modules; and each print module has a respective pressure control system for dynamic fine control of ink pressure in each individual print module.

Abstract: A modular inkjet printhead includes a plurality of printhead modules arranged end on end in a row. Each printhead module includes: a substrate having a plurality of parallel ink supply channels extending longitudinally along a length thereof and a plurality of parallel printhead segments. Each printhead segment extends longitudinally along a length of the substrate and has a plurality of print chips arranged end on end in a row. A plurality of fingers extend longitudinally from opposite ends of each printhead module, each finger including a portion of a respective one of the printhead segments. The fingers of neighboring printhead modules are interdigitated such that printhead segments of neighboring printhead modules overlap.
