  • Patent number: 8094328
    Abstract: An image forming apparatus and a method to control the same. The image forming apparatus determines whether the object to be printed is real money. If the object is real money, the image forming apparatus prints a variety of counterfeit money discrimination information (e.g., the counterfeit money preventing pattern, the warning message, or the unique number of the image forming apparatus used for printing the money) on the back side of the copy of the money, and prints the original image of the money on the front side of the copy of the money without any change. Therefore, the image forming apparatus can color-print the original image of the money without any change, and can prevent the copied money from being used as counterfeit money.

  • Patent number: 7769308
    Abstract: An image forming apparatus and a method of controlling the image forming apparatus. When print data is printed, the remaining amount of toner of each of the CMYK colors is analyzed. When print data is printed, the apparatus analyzes an original color of the print data and analyzes respective remaining amounts of toner of a plurality of colors. If the remaining amount of toner of any of the plurality of colors is insufficient, the apparatus generates a plurality of corrected sample images having colors similar to the original color, the similar colors being obtained by combining colors of toner other than that of the insufficient remaining amount of toner, and prints a report including the generated plurality of corrected sample images. This allows the user to print their preferred colors even if the remaining amount of toner of any color is insufficient, thereby increasing convenience and economic efficiency.

  • Publication number: 20100134842
    Abstract: A system and method of managing a shared printer with radio frequency identification (RFID) includes at least one RFID chip containing information about task permission for users, an RFID transceiver unit to periodically retrieve information about the RFID chip, a controller to determine whether to output a document based on task permission held by a user associated with the RFID chip retrieved by the RFID transceiver unit, and a printing unit to form images on a printing medium in response to a control signal from the controller. It is possible to allow, for example, printing and facsimile transmission by giving specific permission to each user and allows a manager to inspect a use specification by the RFID transceiver unit. The RFID transceiver unit is included in a printer and periodically retrieves information about an RFID chip and determines whether a document is to be output based on task permission held by a user associated with the retrieved RFID chip.

  • Publication number: 20080144131
    Abstract: An image forming apparatus includes a scan unit, a handwriting determining unit, a corresponding image detection unit, a storage unit, a print unit and a controller. In an extraction copy mode, the image formation apparatus scans an original document and detects handwriting marks of a user, extracts original document images of portions of the original document identified by handwriting marks from the scanned images, and stores and prints the original document images. Therefore, a user who only wants to copy portions of a document does not have to cut up and re-paste the document. In a clean copy mode, the image forming apparatus scans the original document to provide scanned images, detects the handwriting marks of the user in the scanned images, extracts clean original document images from which the handwriting marks are removed, and stores and prints the clean original document images.
