Abstract

Startup and shutdown of an ink system in a Rayleigh synchronous ink jet printer presents a formidable task. A main limitation during shutdown is the creation of a negative pressure in the fluid system, thus drawing air in through one or more orifices and promoting subsequent failures. Air ingestion tends to occur in the one particular orifice offering the least resistance.
