ABSTRACT:
A method for cleaning the nozzle plate of an inkjet printhead includes the steps of: providing a solvent on the nozzle plate; loosening debris collected on the nozzle plate by brushing the nozzle plate in the presence of the solvent with a brush; applying a cleaning solvent to the nozzle plate, and subsequently removing the cleaning solvent and debris from the nozzle plate by vacuum cleaning. Application of the cleaning solvent and the subsequent removal of the cleaning solvent provides a movement of solvent over the nozzle plate.
