Abstract: Embodiments of the invention are directed to a dual hopper assembly for use in a credential processing device, a credential processing device that includes a dual hopper assembly, and methods of feeding substrates in a credential processing. One embodiment of the dual hopper assembly comprises an upper hopper configured to support one or more card substrates, a lower hopper configured to support one or more card substrates and an input feed roller. The input feed roller is positioned between the upper and lower hoppers and is movable between a first position, in which the input feed roller engages a bottom substrate supported in the upper hopper, and a second position, in which the input feed roller is displaced from the bottom substrate.

Abstract: Embodiments of the invention are directed to a dual hopper assembly (104) for use in a credential processing device (100), a credential processing device (100) that includes a dual hopper assembly (104), and methods of feeding substrates in a credential processing device (100). One embodiment of the dual hopper assembly (104) comprises an upper hopper (106) configured to support one or more card substrates (102), a lower hopper (108) configured to support one or more card substrates and an input feed roller (140). The input feed roller is positioned between the upper and lower hoppers and is movable between a first position (132), in which the input feed roller engages a bottom substrate (102A) supported in the upper hopper, and a second position (134), in which the input feed roller is displaced from the bottom substrate.
