    Abstract: PROBLEM TO BE SOLVED: To reduce ink leakage from a nozzle opening.SOLUTION: In general, in a first aspect, a droplet deposition system includes: a jetting assembly 112 including one or more modules capable of ejecting droplets; a plurality of conduits in fluid communication with the jetting assembly 112; and a valve 101 coupled to the conduits and adjustable between a first state in which fluid flow through the conduits is substantially prevented and a second state in which fluid flow through the conduits is allowed.

    Abstract: PROBLEM TO BE SOLVED: To reduce drive voltage of a piezoelectric ink jet module and improve injection accuracy.SOLUTION: Polymer films (for example, flexible print members 30, 31, 32) located between piezoelectric elements 34, 34' and storage parts in an injection body provide an effective seal for the storage parts and electrodes are positioned on the side of the piezoelectric element 34, 34' in which operation is performed, thus reducing the magnitude of the drive voltage. This location of the flexible members can enhance electrical and mechanical separation between the storage parts, so as to improve injection accuracy. The deformation characteristic of the polymer further reduces distortion of an ink jet head.
