流体噴射装置
Document Type and Number:
Japanese Patent JP4150692
Kind Code:
B2
Abstract:
In one embodiment, the present invention recites a fluid ejection device comprising a first drop ejector configured to cause fluid having a first drop weight to be ejected from the firing chamber, and includes a first heating element. A first bore, disposed within an orifice layer proximate to the first drop ejector, is associated with the first drop ejector. A second drop ejector is configured to cause fluid having a second drop weight to be ejected from the firing chamber, and includes a second heating element. A second bore, disposed within the orifice layer proximate to the second drop ejector, is associated with the second drop ejector. A voltage source, coupled in series with the first drop ejector and the second drop ejector, is configured to generate a first voltage for activating the first drop ejector individually and a second voltage for activating the first drop ejector and the second drop ejector substantially concurrently.
