Abstract
A method for controlling print speed of an imaging device is provided. The imaging device includes at least one reservoir for supplying liquid ink to a print head and a level sensor in the reservoir. The method comprises measuring an image density of at least a portion of a print job for the imaging device. A state of a level sensor in a print head reservoir is detected. The print speed is adjusted to a target speed in response to the level sensor indicating an open loop state. The target speed is a function of the image density. The print speed is adjusted to a default speed in response to the level sensor indicating a closed loop state.
