ABSTRACT:
A method of unblocking nozzles in a printhead 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 from a first position in which the contact surface is sealingly engaged with the face to a second position in which the contact surface is disengaged from said face. The movement causes the contact surface to be peeled away from the face during disengagement.
