Abstract: An image processing apparatus for preventing unauthorized uses of image data by allowing the addition of a specific image in a black-and-white mode even when it is set that a specific image is added in a color mode. When a document is copied, a control section determines whether the apparatus is in a color mode or a black-and-white mode. When in a black-and-white mode, an adding condition determining section reads a set security level and a differential value and determines a security level lower than the one in a color mode. Based on the security level in a black-and-white mode, an adding condition of a specific image is determined. The specific image adding section adds a specific image different from the one in a color mode based on the adding condition. A black-and-white image added with the specific image is printed.

The image processing apparatus sends image data having added specific information to a management server, and the management server stores inputted image data. The management server adds information concerning the own apparatus to image data as specific information, and sends the image data to the image processing apparatus. The image processing apparatus adds information concerning the own apparatus to image data as specific information, and prints the image data.

Abstract: It is determined whether or not a jammed document is necessarily returned to a document tray when a jam of the document is caused within a carrier path and, then, the elevation operation of the document tray is controlled on the basis of its result of the determination. Since the jammed sheet of which reading has not been completed should be returned to the document tray, the document tray is moved down. Since the jammed sheet of which reading has been completed should not be returned to the document tray, the document tray is maintained at a position as it is. When the apparatus stops due to the carrying jam, a time required for processing the document is shortened.

Abstract: An image processing device determines, based on an IP address received from an external device, whether any processing according to information received from the external device should be performed or not. A path of communication with the external device is examined from a network address. When the external device that is a transmission source of information is an external device outside a predetermined range, specifically, for example, when the external device is an external device connected to a communication network that is further external to the communication network connected to the image processing device, the image processing device inhibits any processing that follows an image data processing command received from the external device. The image processing device also inhibits any processing that follows a command of adjusting the image processing device which command is received from outside the predetermined range.

Abstract: In accordance with the state of a document tray upon powering on a power source, the elevation operation of a document tray is controlled. In the case that the document tray is located not at the highest position, not at the lowest position, but at a middle position upon powering on the power source, the document tray is allowed to remain at the middle position as it is without performing the elevation of the document tray. In the case that the document tray is located at the highest position, the document tray is moved down. By reducing the wasteful operation (the initial operation) after powering on the power source, it is possible to reduce the operation time and the efficient sheet processing can be realized.

Abstract: When a document detector provided on a document tray is ON (S11: YES), a controller judges whether or not a document is of a standard size, on the basis of a document size table stored in a storing unit (S12). When the document is of a standard size (S12: YES), after a predetermined time has elapsed (S13: YES), the controller elevates/lowers the document tray on the basis of a detection output of a guide-in roller position detector and causes the document tray to wait in a state capable of supplying and conveying the topmost layer of documents immediately. An image forming apparatus thus constructed can make a judgment as to whether or not to execute supply and conveyance of documents, according to the mount state of the documents.
