Abstract

A thermal ink jet (TIJ) printing system utilizing an indirect marking means is disclosed. A TIJ printhead 1 forms an image on an intermediate transfer drum 2, belt 3, or other media where the image may be subsequently transferred to a copy sheet 4 provided by a copy sheet transport 5 as represented in the Figures. The intermediate transport enables several advantages over direct marking TIJ systems, for example: a.) the ability to control ink flow and migration to the copy sheet; b.) greater uniformity in print plane spacing for better ink drop placement control; and c.) a wide choice of print media (paper types) may be used.
