Variable drop mass inkjet drop generator |
摘要 |
An inkjet printing device employs an inkjet printhead with a plurality of drop generators to eject drops of ink. Each drop generator includes a planar heater resistor, a protection layer having a first heating surface on the heater resistor and a second heating surface entirely surrounding the first heater surface on the heater resistor, and an ink ejection nozzle. The drop generator vaporizes ink at the first heating surface and ejects a drop of ink of a first mass from the nozzle when a first range of energies is applied to the heater resistor. The drop generator vaporizes ink at the first heating surface and the second heating surface and ejects a drop of ink of a second mass from the nozzle when a second range of energies is applied to the heater resistor.
