Nozzle guard for a printhead |
| abstract |
An ink jet printhead has a number of printhead chips ( 10 ). Each printhead chip ( 10 ) has a wafer substrate ( 16 ). A plurality of nozzle arrangements ( 10 ) is positioned on the wafer substrate. Each nozzle arrangement ( 22 ) has nozzle chamber walls and a roof wall that define a nozzle chamber ( 34 ) and a nozzle opening ( 24 ) in fluid communication with the nozzle chamber. An actuator ( 28 ) is operatively arranged with respect to each nozzle arrangement ( 10 ) to eject ink from the nozzle chamber through the nozzle opening. A nozzle guard ( 80 ) is positioned over the printhead chip. The nozzle guard has a support structure ( 86 ) and a planar cover member ( 82 ). The planar cover member is positioned on the support structure. The planar cover member defines a plurality of passages ( 84 ). Each passage ( 84 ) is in register with a respective nozzle opening ( 24 ). The planar cover member ( 82 ) is less than 300 microns thick. |
