Abstract

An image forming apparatus includes a storage unit for storing a primary key issued by an activation key issuing system and storing a key issuing program, a reception unit for receiving an instruction to issue an activation key that can be used in another image forming apparatus in a local network, a control unit configured to generate the activation key that can be used in the another image forming apparatus on the basis of the primary key and the key issuing program, and a printing unit configured to print generated key information to be input to the another image forming apparatus when using the activation key generated by the control unit in the another image forming apparatus on a sheet to output the sheet.

Claims

1. An image forming apparatus comprising:

a storage unit for storing a primary key as an activation key issued from an external official activation key issuing system and for storing a key issuing program for additionally issuing the activation key based on the primary key;

a reception unit for receiving an instruction to issue the activation key that can be used in another image forming apparatus belonging to the same local network as the image forming apparatus, the another image forming apparatus being installed with an inactivated application;

a control unit configured to generate the activation key that can be used in the another image forming apparatus, on the basis of the primary key and the key issuing program, when the reception unit receives the instruction to issue the activation key; and

a printing unit configured to print generated key information to be input to the another image forming apparatus when using the activation key generated by the control unit in the another image forming apparatus on a sheet to output the sheet.

2. The image forming apparatus according to claim 1, wherein, the control unit does not generate the activation key when the reception unit receives the instruction to issue the activation key that is used in another image forming apparatus outside the local network to which the image forming apparatus belongs.

3. The image forming apparatus according to claim 1, wherein,

the primary key contains license information indicating the number of licenses of the activation keys, and

after generating the activation keys of the number of licenses indicated in the license information, the control unit does not generate the activation key when the reception unit receives the instruction to issue the activation key.

4. The image forming apparatus according to claim 1, further comprising a communication unit for communicating with the another image forming apparatus, wherein

the communication unit obtains a serial number of the another image forming apparatus from the another image forming apparatus when the reception unit receives the instruction to issue the activation key, and

the control unit uses the serial number of the another image forming apparatus to perform calculation based on a predetermined arithmetic expression, and generates the activation key that can be used in the another image forming apparatus.

5. The image forming apparatus according to claim 1, wherein,

the reception unit receives an instruction to transfer the primary key to the another image forming apparatus,

when the reception unit receives the instruction to transfer the primary key to the another image forming apparatus, the printing unit prints primary key information to be input to the another image forming apparatus for transferring the primary key to the another image forming apparatus on a sheet to output the sheet, and

after finishing the print out of the primary key information by the printing unit, the control unit deletes the primary key from the storage unit.

6. An image forming system comprising:

a first image forming apparatus that is the image forming apparatus according to claim 1; and

a second image forming apparatus that is an image forming apparatus in which an inactivated application is installed and is an image forming apparatus other than the first image forming apparatus, belonging to the same local network as the first image forming apparatus, wherein

the second image forming apparatus activates the application when the generated key information is input to the second image forming apparatus.

7. The image forming system according to claim 6,

the second image forming apparatus includes an image reading unit for reading an image, wherein

the image reading unit reads an image on the sheet on which the generated key information is printed, so as to input the generated key information to the second image forming apparatus.
