Pump control mechanism, printer incorporating the same, and pump control method

Image Number 11 for United States Patent #7607750.

A pump member is cyclically moved to apply an air pressure to a liquid supply source to thereby supply liquid stored therein to a reservoir member. A driving source is driven in accordance with control information to move the pump member. A position sensor senses a position of the pump member. A first storage stores target information indicative of a target driving speed of the driving source. A first calculator obtains drive information indicative of an actual driving speed of the driving source based on the sensed position of the pump member. A second calculator obtains a difference between the target driving speed and the actual driving speed, and obtains correction information for reducing the difference. A corrector corrects the control information with the correction information.
