Abstract: In an inkjet printer, a low surface energy material is applied to a printhead face and a drip bib during a printhead maintenance operation. The low surface energy material forms a thin layer on the printhead face and drip bib to resist adhesion of ink to the printhead. The low surface energy material can be a layer of silicone oil.
