Abstract
A laser printer including a disposable debris collection and exhaust duct, and an imaging region at which a laser beam is imaged onto a medium being printed, and a laser system for producing the laser beam and scanning the laser beam across the imaging region. The debris collection duct collects debris produced when the laser beam is imaged onto the medium, and comprises a collection region having a laser beam window, a collection opening in communication with the imaging region, an input port coupled to a source of clean air, and an exhaust port coupled to a source of relatively low pressure on an end of the duct opposite the collection opening from the input port. The laser beam is imaged onto the medium through the laser beam window and the collection opening. Debris produced during printing enters the duct through the collection opening and exits through the exhaust port.
