A media stapling system for an image forming device. The media stapling system comprises a stapler mounted on a motor-driven carriage assembly moveably coupled to a track having portions extending along at least two contiguous edges and included corner of a media stack to be stapled. The carriage assembly and track enables stapling in multiple positions along the long and/or short edges and corners of media of varying sizes positioned in a media support. The track is mounted on a planar frame positioned at an angle from horizontal, providing a relatively small footprint. A controller is in operable communication with the media stapling system and an user interface. The user interface provides a plurality of predetermined stapling patterns for selection with the controller controlling the media stapling system to staple the media stack using a selected one of the plurality of stapling patterns.
