A method for resetting an apparatus configured for stapling tissue includes providing the apparatus with a cam member of the apparatus in a fired position. The method further includes changing the polarity of a motor of the apparatus and activating the motor such that the cam member rotates in a second direction from the fired position back to a home position. The apparatus further includes a stapling head assembly and a shaft assembly coupled to the stapling head assembly. The apparatus further includes a body coupled to the shaft assembly. The body comprises a motor and a cam member that is configured to rotate in response to activation of the motor. Rotation of the cam member in a first direction from the home position to the fired position results in actuation of the stapling head assembly. Another method for resetting the apparatus includes removing at least a portion of the casing where the cam member is positioned and rotating the cam member in a second direction from the fired position to the home position.
