1. A surgical stapler comprising:
an elongate shaft having a proximal end, a distal end, and a longitudinal axis extending between the proximal end and the distal end;
a firing beam having a proximal end and a distal end, at least a portion of the firing beam being longitudinally slidable within the elongate shaft; and
a jaw assembly at the distal end of the elongate shaft, the jaw assembly comprising:
a first jaw defining an anvil;
a second jaw defining a reload support configured to receive a reload cartridge having a plurality of staples deployable therefrom;
a first lockout lever pivotably coupled to the second jaw; and
a second lockout lever pivotably coupled to the second jaw and pivotable independently of the first lockout lever;
wherein the first lockout lever is configured to restrict distal movement of the firing beam when no reload cartridge is positioned in the reload support and allow movement of the firing beam both when a previously fired reload cartridge and when an unfired reload cartridge is positioned in the reload support and the second lockout lever is configured to restrict distal movement of the firing beam when a previously fired reload cartridge is positioned in the reload support.
