Abstract
A self adjusting jam prevention guide and jam clearance baffle for a printing machine. A moveable guide is attached to a machine subsystem module and is moveable from a first position to a second position. In the first position the guide bridges a gap between the machine subsystem module and a preceding subsystem module. In the second position, the guide is retracted from the gap to allow easy removal of one of the subsystem modules. The moveable guide is preferably self actuated by the use of a biasing device and a ramped section so that the movement of one of the adjacent subsystem modules causes extension and retraction of the guide. A jam clearance aid is further attached to the exit of the machine subsystem module. The clearance aid uses a J-shaped channel to cause a sheet fed into a jammed sheet to buckle and cause both the first jammed sheet and subsequent sheets to be partially ejected from the paper path for easy removal therefrom.
