| 20100194822 | APPARATUS FOR PRINTHEAD MOUNTING - A printhead assembly including a printhead module and a mounting structure is described. The printhead module is mounted on a receiving surface of the mounting structure and includes a first edge and a second edge opposite the first edge. The first and second edges extend beyond edges of the receiving surface by a first distance in a first direction and are positioned between featured edges of the mounting structure in a second direction that is substantially perpendicular to the first direction. Each featured edge includes a first feature protruding from the featured edge by a second distance in the first direction, where the second distance is greater than the first distance. The first features extend beyond the first and second edges of the printhead module. Each featured edge includes a recessed second feature configured to receive a first feature of a neighboring mounting structure. | 08-05-2010 |
| 20110148988 | FLUID DROPLET EJECTING - A system for ejecting droplets of a fluid is described. The system includes a substrate having a flow path body that includes a fluid pumping chamber, a descender fluidically connected to the fluid pumping chamber, and a nozzle fluidically connected to the descender. The nozzle is arranged to eject droplets of fluid through an outlet formed in an outer substrate surface. The flow path body also includes a recirculation passage fluidically connected to the descender. The system for ejecting droplets of a fluid also includes a fluid supply tank fluidically connected to the fluid pumping chamber, a fluid return tank fluidically connected to the recirculation passage, and a pump fluidically connecting the fluid return tank and the fluid supply tank. In some implementations, a flow of fluid through the flow path body is at a flow rate sufficient to force air bubbles or contaminants through the flow path body. | 06-23-2011 |
