Abstract: A print head assembly for an ink-jet printer operable with a continuous ink supply system is disclosed, with an ink compartment, a foam insert, an ink fill port, and a spacer. The ink fill port receives ink fed from an external supply and to be printed by the print head assembly. The ink compartment stores the ink to be printed. The foam insert is in the ink compartment and takes up the ink to be stored. The spacer extends into the ink compartment, provides for the formation of a clearance between the foam insert and the ink fill port and surrounds the ink fill port either completely or with one or more gaps having a gap width. The gap width of none of the gaps presents an aperture angle of more than 25% of 36° with respect to a center of the ink fill port.

Further, a method of manufacturing a print head assembly is disclosed.

Abstract: One example provides a replaceable cartridge for user-installation in a printer system. The replaceable cartridge includes a cartridge body, a cartridge lid and a lid manifold. The cartridge lid covers the cartridge body and includes a lid aperture to supply printing fluid into the cartridge body. The lid manifold is mounted to the cartridge lid and includes a lid manifold input port to be fluidly connected to and disconnected from a carriage manifold of the printer system. The state of the fluid connection depends on a pivot position of the carriage manifold, if the replaceable cartridge is installed in the printer system.
