ABSTRACT:
A method of maintaining a printhead in an operable condition and/or remediating a printhead to an operable condition is provided. The method comprises the steps of: (i) providing an endless maintenance belt having a contact surface for sealing engagement with an ink ejection face of the printhead; (ii) moving the belt into a first position in which a clean part of the contact surface is sealingly engaged with the face; (iii) moving said belt into a second position in which the contact surface is disengaged from the face, thereby providing an inked part of the contact surface; (iv) conveying the belt such that the inked part of the contact surface is conveyed away from the printhead and past a cleaning station, the cleaning station cleaning the inked part of the contact surface; and (v) optionally repeating steps (ii) to (iv).
