ABSTRACT:
A removable seal for the face of a printhead is a laminate tab made of a flexible, tear resistant material having a layer of low temperature melt material on one side thereof. The seal is molded to the face of the printhead by applying heat to the laminate tab to reflow the low temperature melt material onto the face of the printhead. The seal extends beyond at least one side of the face of the printhead to form an easily graspable, removable tab. The seal is used during shipping and handling to prevent ink from leaking from the printhead and to prevent contamination and damage of the nozzles.
