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 method of coating threads using a printhead having rows of nozzles extending along a length of the printhead. The method includes the steps of: feeding the thread along a length of the printhead; and ejecting ink from the rows of nozzles towards the thread. Thread-coating modules and thread-coating systems make use of the method described.

Abstract: A printhead module includes: a monolithic substrate having alternate longitudinal slots and longitudinal ink supply channels defined through a thickness of the substrate and extending parallel with each other along a length of the substrate; and a plurality of rows of print chips mounted on a front face of the substrate, each row of print chips receiving ink only from a respective one of the ink supply channels. Each one of the longitudinal slots is configured to supply power and data only to a respective one of the rows of print chips.

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 inkjet printing system includes: (a) an inkjet printhead having a rigid elongate manifold with first and second parallel ink supply channels extending along a length of the manifold between respective ink ports positioned at opposite ends thereof; and a plurality of printhead chips mounted to a lower surface of the manifold, the ink supply channels supplying ink to the printhead chips via ink outlets defined in the lower surface. One end of the manifold has a first ink inlet port for the first ink supply channel and an ink outlet port for the second ink supply channel. The other end of the manifold has a first ink outlet port for the first ink supply channel and a second ink inlet port for the second ink supply channel. An ink delivery system is configured to flow ink along the first and second channels in opposite directions.

Abstract: A printhead module for a modular pagewide inkjet printhead. The printhead module has only four rows of print chips configured for printing four different inks, each print chip having multiple nozzle rows for redundant monochrome printing of one respective ink. A print zone of the printhead module has a width of less than 100 mm across the four rows of print chips.
