喷墨打印头和采用中央供墨通道的方法

Inkjet printhead and method employing central ink feed channel
Abstract:
An inkjet printhead (100) and a method (200) of supplying viscous ink employ a central ink feed channel (130). The inkjet printhead (100) includes a bridge beam (110) that supports an ejector element (106), a pair of lateral ink feed channels (120) adjacent to the bridge beam (110), and a central ink feed channel (130) through the ejector element (106) and bridge beam (110). The pair of lateral ink feed channels (120) and the central ink feed channel (130) connect between an ink reservoir (140) below the bridge beam (110) and the bubble expansion chamber (104). The method (200) includes providing (210) a central ink feed channel in a bridge beam of a printhead and flowing (220) viscous ink from an ink reservoir through a combination of the provided central ink feed channel and a pair of lateral ink feed channels.
Abstract(Chinese):
