ABSTRACT:
One aspect of this disclosure relates to a printer apparatus, comprising an orifice plate having a nozzle orifice formed therein. Ink can flow through the nozzle orifice. The orifice plate has an orifice plate surface energy and the ink has an ink surface tension. A wiper blade can be disposed proximate the orifice plate. The wiper has a wiper blade surface energy. The wiper blade surface energy is greater than or equal to the ink surface tension. The ink surface tension is greater than or equal to the orifice plate surface energy.
