ABSTRACT:
A method of maintaining a printhead in an operable condition is provided. The method comprises the steps of (a) providing an elastically deformable pad having a contact surface for sealing engagement with an ink ejection face of the printhead; and (b) moving the pad between a first position in which the contact surface is sealingly engaged with the face and a second position in which the contact surface is disengaged from the face. The movement causes the contact surface to be progressively contacted with the face during sealing engagement and peeled away from the face during disengagement.
