An information processing apparatus in accordance with the present disclosure includes an identification number detecting circuit configured to detect an identification number included in data to be printed, a conversion information obtaining circuit configured to obtain conversion information, associated with the identification number in the data to be printed, from association information associated with an item information displayed to be associated with the identification number in the data to be printed of an item, an information conversion processing circuit configured to convert the identification number, included in the data to be printed, according to the conversion information obtained from the association information by the conversion information obtaining circuit, and a print data generating circuit configured to generate print data for instructing an image forming apparatus to print an output image that includes the converted identification number.

Information processing apparatus and method for the replacement of personal information in print documents

An information processing system includes at least one information processing terminal and a first information processing apparatus. When an instruction for selecting a user authentication mode, which is received, from a user, by a user interface of the information processing terminal, selects a second user authentication mode, circuitry of the first information processing apparatus determines whether a sum of charges for services used by the user while logging in the information processing terminal via the second user authentication mode after a most recent login via a first user authentication mode exceeds a predetermined amount, and generates an authentication result indicating that the user is not the authenticated user.

Information processing system and user authentication method

An image forming apparatus includes circuitry that connects to one or more first information processing apparatuses via a virtual private network in response to a request to connect from at least one of the one or more first information processing apparatuses and establishes a first wireless communication network among the image forming apparatus and the first information processing apparatuses to enable wireless communication among the image forming apparatus and the first information processing apparatuses.

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

A liquid cartridge includes an ink bag for storing liquid and being capable of changing its shape, a housing for storing the ink bag, a guiding tube member for being placed in the ink bag, and a liquid supply outlet for providing the liquid to outside the ink bag and being connected to an end of the guiding tube member. Another end of the guiding tube member is placed close to or touching a bottom of the ink bag. The liquid cartridge further includes a bottom plate for supporting the bottom of the ink bag. The bottom plate is configured to be moved with respect to the housing. As remaining ink in the ink bag decreases, the bottom plate is moved to be in an inclining state by an inclination adding member that is placed in a cartridge installing unit of an apparatus.

Liquid container and image forming apparatus

Comprises a panel, and a coordinate control section that detects a point touched on the panel and generates a signal according to the detected point. The coordinate control section generates a coordinate signal that shows coordinates of a touched point, when one point touch on the panel has been detected. When simultaneous touches of two or more points on the panel have been detected, the coordinate control section generates a control signal that shows a control set in advance corresponding to the number of touched points.

Information input/output apparatus, information input/output control method, and computer product

Comprises a panel, and a coordinate control section that detects a point touched on the panel and generates a signal according to the detected point. The coordinate control section generates a coordinate signal that shows coordinates of a touched point, when one point touch on the panel has been detected. When simultaneous touches of two or more points on the panel has been detected, the coordinate control section generates a control that shows a control set in advance corresponding to the number of touched points.

A positioning device for preventing an endless belt passed over a plurality support rollers from being shifted to either of opposite sides in the axial direction of the rollers. A pair of forcing elements are located at both ends of at least one of the support rollers for forcing back, when the belt is shifted toward either of opposite ends of the support roller to contact the end of the latter, the belt toward the center of the roller in the axial direction of the roller. The forcing elements each are implemented as a plurality of spaced flanges. The maximum diameter of the flanges sequentially increases from the innermost flange to the outermost flange in the axial direction of the roller. The plurality of flanges may be replaced with a single spiral flange.

Positioning device for an endless belt

An image forming apparatus allows an image carrier, a developing unit and a cleaning device each having a different service life to be detachably mounted in a housing thereof. The developing and cleaning devices are rotatably supported to constitute an image forming unit. The image forming unit is detachably supported by a first rotatable body which is mounted to the apparatus housing. The image carrier is detachably supported by opposite side plates of the apparatus housing or by a second rotatable body which is supported by the apparatus housing to be rotatable independently of the first rotatable body. A positioning arrangement is provided for controlling the rotation of the developing and cleaning devices so that the image forming unit and the image carrier may be prevented from interfering with each other when the unit is moved toward and away from the image carrier.
