摘要： A printhead and a method of ejecting liquid droplets are provided. The method includes providing a printhead operable to eject liquid drops having a plurality of drop volumes Vi, for i equal to 1 through n, where n≧2, with Vj>Vi when j>i. One of the plurality of drop volumes is a minimum drop volume Vmin, and a difference in drop volumes between successively larger drops equals (Vk+1−Vk) which is less than Vmin, for k equal to 1 through n−1. The method also includes ejecting liquid drops through the printhead.

摘要： Each liquid dispensing element of an array includes liquid supply, dispensing, and return channels positioned on a substrate. The liquid dispensing channel, in communication with the supply and return channels, includes an outlet opening and is associated with a diverter member. Liquid supply and return passages, in communication with liquid supply and return channels, respectively, extend through the substrate. Liquid supply and return ducts of a liquid manifold are in communication with each liquid supply passage and liquid return passage, respectively. Liquid flows from the liquid supply duct through each liquid dispensing element to the liquid return duct. A liquid drop is ejected from the outlet opening of the liquid dispensing channel of one of the liquid dispensing elements by selectively actuating the associated diverter member to divert a portion of the flowing liquid through the outlet opening of the liquid dispensing channel.

摘要： A liquid dispenser includes a liquid supply channel including an exit having a cross sectional area, a liquid return channel, and a liquid dispensing channel including a cross sectional area and an outlet opening. The outlet opening includes an end that is adjacent to the liquid return channel. The cross sectional area of a portion of the liquid dispensing channel that is located at the end of the outlet opening is greater than the cross sectional area of the exit of the liquid supply channel. A liquid supply provides liquid under pressure from the liquid supply channel through the liquid dispensing channel to the liquid return channel. A diverter member is selectively actuatable to divert a portion of the liquid toward outlet opening of the liquid dispensing channel.
