Abstract: Scanning devices and method of use that accommodate a longer imaging distance while minimizing the size of the device. The scanning device may include an imaging unit having a sensor and optics. The scanning device may further include a target bed for placement of the targeted documents. An imaging distance extends between the imaging unit and the target bed. In one embodiment, the housing may be collapsed after the scanning procedure to reduce the overall device size. Reflective members may also be positioned within the interior of the device to lengthen the imaging distance. Still further embodiments may include a movable imaging unit.

Abstract: A method of authenticating a consumable used in an imaging device includes the steps of providing the consumable with a memory; monitoring usage of the consumable; determining whether the consumable has reached a usage threshold; and, if the consumable has reached the usage threshold, then performing the further steps of: renewing the consumable; generating an authentication code signifying the renewing of the consumable; and storing the authentication code in the memory.

Abstract: A method of fault correction for an array of fusible links includes the steps of storing digital information in a first plurality of fusible links to place the first plurality of fusible links in a first programmed state; storing the digital information in a second plurality of fusible links to place the second plurality of fusible links in a second programmed state; and performing a logic operation to combine the first programmed state with the second programmed state, the logic operation providing an output that is identical to one of the first programmed state and the second programmed state for a respective one of the first plurality of fusible links and the second plurality of fusible links that does not include a faulty bit.
