摘要： 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.

摘要： An inkjet head ejection performance evaluation method includes: printing a test pattern for examining an ejection condition for each nozzle by an inkjet head (100) and reading the test pattern by an image reading device (58); measuring a first depositing position for each nozzle from a read image to calculate an angle deviation amount of the inkjet head based on the first depositing position and pattern information; calculating at least one of a second depositing position and second deposit displacement amount in which an influence due to angle deviation caused is eliminated; calculating a moving amount caused by rotation of the angle deviation amount from a reference position of the nozzle at a reference attaching angle up to a current nozzle position; and calculating, by using these calculation results, at least one of a distance between the adjacent pixels and a third deposit displacement amount including the influence.
