Ink jet printing apparatus having an ink pressure transient suppressor system
An ink jet printer includes a compact ink drop generating module (10) comprising an ink jet print head (14) mounted to a body (12) which contains high and low frequency ink pressure transient suppressing mechanisms (90, 68, 80). These mechanisms inhibit the ingestion of air into print head (14) and...

description | An ink jet printer includes a compact ink drop generating module (10) comprising an ink jet print head (14) mounted to a body (12) which contains high and low frequency ink pressure transient suppressing mechanisms (90, 68, 80). These mechanisms inhibit the ingestion of air into print head (14) and formation of print head clogging air bubbles. The body (12) also includes a purgeble bubble trap (72). Head (14) may be of the air assisted type. Air supplied to the head pressurizes ink at one side (82) of the diaphragm (80) and at the other side (84) of the diaphragm to increase the fluid capacitance of the diaphragm. The module (10) is easy to replace as a unit. |
