Abstract

A combination air knifelprint head arrangement for use in thermal ink jet (TIJ) printers is disclosed. TIJ technology requires that: the paper not contact the print head after imaging; quick drying of the inked image by evaporation or absorption of the ink; the printhead is maintained at a reasonably constant temperature range; the printhead be periodically cleaned to remove paper fibers, excess ink or other residues: and the printhead is easily primed and purged.
