Abstract:
1. A method for printing comprising: advancing a sheeted substrate through a fuser in a process direction, the fuser having a fuser member and a pressure member, at least one of the fuser member and the pressure member being movable by action of at least one pneumatic device, the at least one pneumatic device being actuated to a first position to close a fusing nip between the fuser member and the pressure member at a fusing position and being actuated to a second position to open the fusing nip between the fuser member and the pressure member; applying a release agent to the fuser member; determining a presence of a leading edge of the sheeted substrate at the fusing position corresponding to the fusing nip; actuating the at least one pneumatic device to the first position to close the fusing nip between the fuser member and the pressure member at the fusing position based on the determined presence of the leading edge of the sheeted substrate at the fusing position; advancing the sheeted substrate through the fusing nip in the process direction; determining the sheeted substrate exits the fusing nip by determining a presence of a trailing edge of the substrate at the fusing nip; actuating the at least one pneumatic device to the second position to open the fusing nip between the fuser member and the pressure member for a duration of time based on the determined exit of the sheeted substrate from the fusing nip to substantially prevent transfer of the release agent from the fuser member to the pressure member, wherein any actuation of the at least one pneumatic device to close and/or open the fusing nip occurs only when the sheeted substrate is present in the fusing nip.
