268. An infusion pump assembly for use with a medicament cartridge including a reservoir and a plunger, the infusion pump assembly comprising:
-
a housing having a cartridge receiving area adapted to hold the medicament cartridge; a plunger pusher, located in the housing, and movable between a home position outside the cartridge receiving area and a position within the cartridge receiving area; a drive mechanism, including a motor, operatively connected to the plunger pusher; and a switch located relative to the plunger pusher such that the switch is actuated when the plunger pusher is retracted, from a position where at least a portion of the plunger pusher is within the cartridge receiving area, to a home position. - View Dependent Claims (269, 270, 271)

272. An infusion pump assembly for use with a medicament cartridge including a reservoir and a plunger, the assembly comprising:
-
a housing having a medicament cartridge receiving area; a plunger pusher movable in and out of the cartridge receiving area; a drive mechanism, including a motor and a controller, that drives the plunger pusher; and a controller that automatically causes the motor to withdraw the plunger pusher out of the cartridge receiving area (a) after receiving a signal from the encoder indicating that a predetermined number of rotation counts of the motor, which indicate that the reservoir is empty, has occurred or (b) when there is a lack of encoder signals. - View Dependent Claims (273, 274)
