Abstract
An apparatus and method for drying a receiver media ( ) in an ink jet printer. The apparatus generally comprises a means for creating a pressure differential between the upper surface ( ) and the lower surface ( ) of the receiver media ( ), wherein the pressure at the lower surface ( ) of the receiver media ( ) is lower than the pressure at the upper surface ( ) of the receiver media ( ). The pressure differential-creating means may include a vacuum pump ( ) adapted to generate a vacuum at the lower surface ( ) of the receiver media ( ) or an air pump ( ) adapted to pass air currents ( ) across the lower surface ( ) of the receiver media ( ) to cause a “Bernoulli effect”. The method generally comprises the steps of depositing ink droplets ( ) onto the upper surface ( ) of the receiver media ( ); and creating a pressure differential between the upper surface ( ) and the lower surface ( ) of the receiver media ( ), whereby carrier fluid contained in ink droplets ( ) is drawn through the receiver media ( ) from the upper surface ( ) to the lower surface ( ).
