System and method for inducing tensioning of a flexible nozzle member of an inkjet printer with an adhesive

Abstract

This present invention is embodied in a printing system and method for inducing shrinkage-tensioning of a flexible nozzle member of a printhead portion of an inkjet printer with an adhesive and novel arrangement. The printing system of the present invention includes a nozzle member securely coupled to a printhead body with an adhesive arrangement that allows shrinkage-induce tensioning of the nozzle member. The adhesive arrangement includes having an adhesive located between a top portion of the printhead body and the flexible nozzle member. The top portion has a mechanical structure such that it induces tensioning of the flexible nozzle member during thermal expansion of the adhesive. Namely, the adhesive arrangement of the printing system of the present invention is capable of efficiently tensioning, and thus, flattening the flexible nozzle member during the adhesion process of the nozzle member. As a result, trajectory errors of ejected ink droplets from the nozzles are reduced.
