Abstract
A continuous liquid ejector includes a structure including a wall. A portion of the wall defines a nozzle having a first fluidic resistance R1. A first liquid feed channel is in fluid communication with the nozzle. The first liquid feed channel has a second fluidic resistance R2. A first drop forming mechanism is associated with the first liquid feed channel. A second liquid feed channel is in fluid communication with the nozzle. The second liquid feed channel has a third fluidic resistance R3. The first fluidic resistance R1 is less than the second fluidic resistance R2 plus the third fluid resistance R3 (R1<(R2+R3)). A second drop forming mechanism associated with the second liquid feed channel.
