Abstract: A method of preparing a printhead for dry shipment. The method includes the steps of: treating an ink pathway in the printhead with an aqueous treatment fluid containing at least one ink-soluble solvent having a boiling point of at least 150 degrees; and drying the printhead so as to leave a film of liquid solvent on a surface of the ink pathway. The film of liquid solvent solubilizes organic materials leached or outgassed from the printhead during dry storage or shipment.
