ABSTRACT:
A shutdown procedure is provided for removing all solvent ink from the printhead of an ink jet printer system that uses volatile ink for printing. A shutdown method is provided for an inkjet printer that uses volatile inks for printing. Initially, a colorless flush fluid is provided which readily dissolves the ink. The flush fluid is crossflushed through the drop generator and caused to weep out of the orifices in the drop generator to dissolve and rinse away ink residues from the charge plate and the exterior of the orifice plate. The flush fluid is used to rinse off charging electrodes of the charge plate, the catcher face, and the catcher return line. Fluid crossflushed through the drop generator cleans the interior of the drop generator and cleans the crossflush valve.
