Abstract
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.
Claims13
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.
A management system comprising an image processing apparatus executing a process corresponding to a requested function and a management apparatus managing said image processing apparatus, wherein
- said image processing apparatus includes:
- 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 for 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;
- and
- said management apparatus includes:
- an obtaining unit obtaining specifying information allowing specification of said unique information and said changeable information stored in said second storage unit;
- and
- an issuing unit issuing said cancellation information corresponding to said unique information and said changeable information, based on said specifying information obtained by said obtaining unit.
A control method of controlling an image processing apparatus including a storage unit and an operation unit, executing a process corresponding to a requested function, comprising the steps of:
- storing information input for executing said function as registration information in said storage unit;
- receiving an instruction requesting erasure of the registration information stored in said storage unit through said operation unit;
- erasing the registration information stored in said storage unit, in response to reception of said instruction;
- setting operation restriction of said image processing apparatus, in response to erasure of said registration information;
- storing unique information unique to said image processing apparatus and changeable information changed in response to erasure of said registration information in said storage unit;
- receiving an input of cancellation information for cancelling said operation restriction through said operation unit;
- determining, in response to reception of the input of said cancellation information, whether or not said received cancellation information is cancellation information corresponding to said unique information and said changeable information stored in said storage unit;
- and
- cancelling said operation restriction if said received cancellation information is determined to be the cancellation information corresponding to said unique information and said changeable information.
