Image forming apparatus, image forming system and control method in image forming apparatus

An image forming apparatus, comprising:

• an output unit;
• a scanning unit to scan a damaged bank note and to generate image data therefrom;
• and
• a controller to calculate an area of the damaged bank note using the generated image data of the scanned damaged bank note and to control the output unit to output damaged bank note information including the calculated area of the damaged bank note and/or an exchangeable value of the damaged bank note corresponding to the calculated area of the damaged bank note.

An image forming system to determine an exchangeable value of a damaged bank note, the system comprising:

• a host apparatus comprising a host display unit;
• and
• an image forming apparatus, comprising:
• a communication unit to communicate with the host apparatus;
• a scanning unit to scan the damaged bank note and to generate image data therefrom;
• and
• a controller to calculate an area of the damaged bank note using the generated image data of the scanned damaged bank note and to control the communication unit to transmit damaged bank note information including the calculated area of the damaged bank note and/or the exchangeable value of the damaged bank note corresponding to the calculated area of the damaged bank note to the host apparatus,
• wherein the host display unit displays the damaged bank note information received from the image forming apparatus.

A control method of determining an exchangeable value of a damaged bank note, the method comprising:

• receiving, in a host device, image data corresponding to the damaged bank note;
• calculating the exchangeable value of the damaged bank note corresponding to an area of the damaged bank note based on a predetermined exchange guideline stored in the host device;
• and
• receiving, in the host device from an external device, the area of the damaged bank note.
