Patent ID: 8857945

Claim:
An inkjet printing system comprising: a plurality of inkjet printheads, each printhead having nozzles for jetting ink droplets having a vaporizable carder fluid; a support structure to which the plurality of inkjet printheads are mounted, such that a face of each of the printheads of the plurality of printheads is positioned to jet the ink droplets toward a target area through which a receiver transport system moves a receiver during printing; a plurality of caps, each cap having a thermally insulating separator that positions a shield between the face of one of the printheads and the target area for the printhead and creating a printing region between the shield and the target area and a shielded region between the face and the shield, with the shield having at least one opening through the shield through which the nozzles of the printhead can jet the ink droplets to the target area; and an energy source provides energy that can be applied to cause the shields to be heated.
