REMOVE PRINTING FLUID PUDDLES FROM AN EXTERIOR NOZZLE SURFACE OF AN INKJET PRINTHEAD

摘要

A method of removing printing fluid puddles from an exterior nozzle surface of an inkjet printhead includes selectively applying a suction signal for a first time period to a plurality of actuators associated with fluid channels of corresponding nozzles by a control module. The method also includes moving printing fluid within the fluid channels associated with the actuators in response to application of the suction signal. Additionally, the method also includes creating suction in each one of the associated fluid channels and through the corresponding nozzles to remove the printing fluid puddles from the exterior nozzle surface by pulling the printing fluid puddles through the corresponding nozzles and the associated fluid channels in response to movement of the printing fluid within the fluid channels.
