Abstract
A stapler for driving a staple into a sheet stack. The stapler includes a first cartridge configured to receive a first staple defined by a first leg length, and a second cartridge configured to receive a second staple defined by a second leg length. The stapler includes a stapling head configured to drive the staples into the sheet stack, and a cartridge positioning actuator configured to selectively position either the first or the second cartridge over a predetermined position on the sheet stack. The stapler can have a single stationary stapling head, and the cartridges can be moved in position over the stapling head. Alternately, each cartridge can have its own associated stapling head. The stapler can include a sensor to determine the thickness of the sheet stack. A controller can receive a thickness signal from the sensor and determine which of the cartridges to position over the sheet stack.
