Abstract: A printing system that comprises a media transport system for conveying a print media along a media path in a first direction. A plurality of print modules each spanning the print media path along a second direction. Each print module defines a major axis along the second direction. A minor axis that aligns along the first direction and an intermediate axis with each of the print modules. A printhead array that includes printheads spaced from the media path. A fluid regulator portion configured to regulate a fluid pressure in the printhead portion. Each of the print modules are configured to be installed into and removed from the printing system as an integral unit.

Abstract: A printing system that comprises a media transport system configured to transport media along a media path. A printhead module that has a fluid inlet and spanning the media path. An ink delivery system that provides ink to the printhead module that includes a main ink supply and a buffer tank. A first pressure regulation unit that includes an overflow weir over which fluid flows from a fluid chamber to a sump. The fluid chamber is fluidly coupled to the fluid inlet whereby a height of liquid in the fluid chamber regulates a pressure at the fluid inlet. An ink supply control module coupled to the main ink supply, the buffer tank, and to the pressure regulation unit and controlling fluid flow in fluid paths that includes a first fluid path that supplies ink from the main ink supply to the buffer tank. A second fluid path that supplies ink from the buffer tank to the fluid chamber. A third fluid path that receives ink from the sump and returns the ink to the buffer tank.
