Abstract
An inkjet printhead in accordance with the invention includes a base that defines a channel. The channel defines an upper orifice that communicates with a reservoir containing ink and a lower orifice. At least one electrode is actuable to provide an electrostatic field within the channel so as to move ink from the upper orifice toward the lower orifice. The at least one electrode includes an upper electrode layer disposed at the upper orifice and a lower electrode layer disposed at the lower orifice.
