Abstract
Apparatus for separating a receiver from a micro-fluidic contact print head after ink image pixels have been printed by the print head on the receiver, including a print head having a plurality of ink channels for delivering ink to the receiver when the receiver is in ink transfer contact with the print head; including an air supply device and air plenum which are associated with each ink channel and defining an air channel for conducting air to the air plenum; and the apparatus is effective after the ink has been transferred from the plurality of ink channels to the receiver for causing air to be delivered from the air supply device to the air channel and into the air plenum to exert a pressure which causes the separation of the receiver from the print head.

Apparatus for separating a receiver from a micro-fluidic contact print head after ink image pixels have been printed by the print head on the receiver, comprising:
- (a) the print head including a plurality of ink channels for delivering ink to the receiver when the receiver is in ink transfer contact with the print head;
- (b) means including an air supply device and defining a plurality of air plenums each of such air plenums being associated with each ink channel and means defining an air channel for conducting air to the air plenums;
- and
- (c) means effective after the ink has been transferred from the plurality of ink channels to the receiver for causing air to be delivered from the air supply device to the air channel and into the plurality of air plenums to exert a pressure which causes the separation of the receiver from the print head.
