Image processing apparatus, management system and control method thereof

摘要

In an image processing apparatus, an HDD stores registration data, an operation unit receives an instruction requesting erasure of the registration data, and a control unit erases the registration data and restricts operations of the image processing apparatus in response to the instruction. Further, the HDD stores unique information unique to the image processing apparatus and changeable information that is changed in response to the erasure of registration data. If it is determined that a cancellation key generated by a management server and received by the operation unit is a cancellation key corresponding to the unique information and the changeable information, the control unit cancels the operation restriction of the image processing apparatus.

主权项

1. An image processing apparatus executing a process corresponding to a requested function, comprising:
a first storage unit storing registration information registered for executing said function; a receiving unit receiving an instruction requesting erasure of the registration information stored in said first storage unit; an erasing unit, responsive to reception of the instruction by said receiving unit, for erasing the registration information stored in said first storage unit; a restricting unit, responsive to erasure of the registration information by said erasing unit, for restricting an operation of the image processing apparatus; a second storage unit storing unique information unique to the image processing apparatus and changeable information changed in response to the erasure of the registration information by said erasing unit; an input unit receiving an input of cancellation information for cancelling the operation restriction imposed by said restricting unit; a determining unit, responsive to said input unit receiving input of said cancellation information, for determining whether said received cancellation information is cancellation information corresponding to said unique information and said changeable information stored in said second storage unit; and a cancelling unit cancelling, if said received cancellation information is determined to be the cancellation information corresponding to the unique information and said changeable information by said determining unit, the operation restriction imposed by said restricting unit.
