An information processing apparatus includes a first communication unit configured to communicate with a first communication apparatus; a second communication unit configured to wirelessly communicate with each of one or more second wireless communication apparatuses; an acquisition unit configured to acquire from the first communication apparatus via the first communication unit an apparatus ID that is held by the first communication apparatus and that is used for identifying one of the one or more second wireless communication apparatuses to or from which the second communication unit transmits or receives data; and a control unit configured to control the second communication unit to transmit or receive the data to or from the one of the one or more second wireless communication apparatuses that is identified by the apparatus ID acquired by the acquisition unit.

Information processing apparatus and wireless communication method

A printing apparatus includes a printer, a first wireless communicator, and a second wireless communicator. The first wireless communicator performs wireless local-area network (LAN) communication. The second wireless communicator transmits, to the information terminal, information required to perform the wireless LAN communication between the printing apparatus and an information terminal. The first wireless communicator receives print data from the information terminal. The printer performs printing based on the print data.

An image processing apparatus includes a first communication unit, an image processing unit, and an authentication unit. The first communication unit performs contactless communication using a radio-frequency identification (RFID). The second communication unit performs wireless communication. The image processing unit performs an image processing job. The authentication unit authenticates a user of the image processing apparatus. In a case where the authentication unit authenticates a user, the second communication unit starts the wireless communication with an external apparatus which has been identified by an identification (ID) communicated from the external apparatus. The image processing unit performs the image processing job using the wireless communication between the second communication unit and the external apparatus.

An information processing apparatus able to recover consistency between file entity data and file management information when detecting an inconsistency therebetween at start-up of the apparatus, while reducing unavailable time of the apparatus as much as possible. A CPU of the information processing apparatus executes a base program stored in a storage unit to check for an abnormality in consistency between file entity data and file management information which are stored in another storage unit. If an abnormality is detected, the CPU executes a program for degeneracy operation stored in still another storage unit to perform a degeneracy operation, and recovers the consistency.

This invention prevents the operation performance drop of an image input and output apparatus even when the frequency of use of the image input and output apparatus is high upon recording log information in a system that comprises the image input and output apparatus. As a characteristic feature of this invention, in an image output system which includes an image input and output apparatus, PC, and server, the PC sends image data to be output by the image input and output apparatus to the server and sends information associated with the storage location of the image data to the image input and output apparatus, the server stores the image data received from the PC, and the image input and output apparatus prints the image data received from the PC and records the information associated with the storage location of the image data as log information about the image data.

The object of this invention is to reduce the effort of deleting and information symbol from a read image. To accomplish this, an image of a document with an information symbol is read (S), and the information symbol is identified in the read image (S). The identified information symbol is decoded (S), and it is determined on the basis of the decoding result whether the data format of the information symbol is a desired one (S). On the basis of the determination, if the data format is the desired one, the information symbol is deleted from the read image (S).

An image-processing apparatus and a control method for this apparatus. Image data is received through a communication section and is recorded by a recording section onto a recording material fed from a manual-feeding tray. Recording materials of various sizes can be set on this tray. The correct recording-material size is obtained based on the size of the received image data and is displayed, and an indication is also given to check whether the recording operation is to be performed. If the manual-feeding operation has been selected, an alarm sound indicates that the image data has been received. The processing then proceeds according to the instruction given in response to the display. Further, if it is determined that a recording error has occurred when the recording operation is performed through manual feeding, the image data is stored in a non-volatile storage.

A printer which records an image on a cut paper sheet must normally assure a margin region at the trailing end side of a record paper sheet in terms of the mechanism of the printer. Conventionally, the margin has a considerably large size. However, this invention aims at reducing the margin size as much as possible and increasing the image record region as much as possible. When a printer of this invention is used in a facsimile apparatus, a problem experienced with a conventional printer, which has a narrow image record region on a record paper sheet, can be prevented. Conventionally, when an image is recorded on a record paper sheet having the same size as that of a received original, the received image is determined as an elongated original image and is divisionally recorded on two record paper sheets, or is recorded on a record paper sheet larger than the received original. This invention prevents this problem.

An image forming apparatus is provided which is capable of immediately performing a recording operation in the case where the apparatus is restored to the operation state from the waiting state. The image forming apparatus has an MPU for performing switching between a normal operation mode, in which the apparatus is operated with normal electric power, and a low power consumption operation mode, in which the apparatus is operated with a low power consumption which is smaller than the normal electric power, so as to reduce electric power consumption. When the MPU switches the mode of the apparatus from the low power consumption operation mode to the normal operation mode, an initial-rotation inhibition signal for inhibiting initial rotation of a motor is generated. In response to the initial-rotation inhibition signal, the initial rotation of the motor is inhibited.

A developer remain amount detecting apparatus includes a detector for detecting a remain amount of a developer within a developer container, a first memory in which a reference value for a comparison with a detection signal from the detector is prememorized, a second memory for memorizing the reference value read from said first memory, input unit for inputting a value for modifying the reference value memorized in the second memory unit, modifying unit for modifying the reference value memorized in the second memory unit based on the value input by the input unit, and judgement unit for judging whether the developer is present by comparing the reference value memorized in the second memory with the detection signal from the detector.
