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.

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.
