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.
