Abstract

An image forming device includes output rollers disposed for ejecting media out of the image forming device, and a single solenoid activated bi-directional output drive mechanism connected to the output rollers for bi-directionally driving the output rollers and for enabling a return path back through the output rollers for duplexing of the media. In an alternate embodiment, the image forming device includes substantially all components necessary for duplexing, integrated with the base engine of the image forming device, but excludes the solenoid activated bi-directional output drive mechanism, for providing a non-duplexing system that is optionally and easily upgradeable to a duplexing system.
