Zusammenfassung:A printhead having an ink ejection face coated with a hydrophobic polymeric material. The polymeric material is comprised of a polysilsesquioxane, such as poly(methylsilsesquioxane) or poly(phenylsilsesquioxane). The printhead is compatible with various printhead maintenance operations requiring contact with the ink ejection face. L'invention concerne une tête d'impression comprenant un côté d'éjection d'encre revêtu d'un matériau polymère hydrophobe. Le matériau polymère est composé d?un polysilsesquioxane, comme un poly(méthylsilsesquioxane) ou un poly(phénylsilsesquioxane). La tête d?impression est compatible avec diverses opérations de maintenance de la tête d'impression qui nécessitent un contact avec le côté d'éjection d'encre.
