Abstract: Upon reception of a data transmission request, an image input device 1 searches for transmission means available for transmission to a destination, such as transfer to FTP server or transmission by e-mail, and lists all the extracted available transmission means. Image input device 1 then creates a selection menu executed as an applet for receiving a selection of transmission methods from the destination. The destination can use the selection menu acquired from image input device 1 to designate the priority order of desired transmission means and a file name in reception of transmitted data. The selection menu thus created is transmitted to the image input device 1.

Abstract: The data transmission apparatus accesses the server using an IP address registered in advance and user information (destination information) is obtained there from. At the same time, group information is sent to the server, and a user name list is obtained from the server based on this information. Only the user names existing on the list are registered in the MFP as destinations from the obtained user name list. As a result, destinations are automatically registered, and only the addresses of persons presumed to use the data transmission apparatus are registered in the apparatus, thereby making the apparatus more convenient to use.

Abstract: Multiple user boxes are created beforehand in the hard disk drive of the MFP. The user specifies his own user box and saves image data therein. If the user extracts the image data from his user box and moves it to a folder on his own personal computer, the MFP 1 detects this action. When this user box is specified during a subsequent reading of image data, the storage destination for the image data is automatically deemed to be the folder on the personal computer to which the image data was previously moved.

Abstract: An image forming system and image forming apparatus capable of suppressing reduced productivity and avoiding the troublesome task of sorting output materials even when image formation becomes impossible. The system and apparatus include a transfer controller that permits job data transfer to another image forming apparatus if image formation of the job data has not started when an impaired image forming state is detected in an image forming apparatus, and that prohibits job data transfer to another image forming apparatus if image formation of job data has already started. In this way, the image formation process can be executed without processing congestion by having another image forming apparatus perform the job data image formation. Moreover, the task of sorting the output material is unnecessary because the job data is not dispersed between the transfer origin and the transfer destination.

Abstract: An image forming apparatus includes a memory for storing a first job and a second job, an output unit for sequentially outputting the first and second jobs stored in the memory, a setter for setting a recall function effective to the first job and a job controller. The recall function is a function enabling a re-output of the first job in accordance with a request of an operator after a completion of the first job. The job controller controls the output unit so as to output the second job a predetermined time later after a completion of the first job where the recall function is set effective to the first job, or output the second job immediately after a completion of the first job where the recall function is set ineffective to the first job.

Abstract: It is determined in S202 whether or not a mismatch between the paper information for the job A and the paper information existing in the printer (the printer 1A, for example) has occurred, and if there is a mismatch between the two types of paper information, it is determined in S205 whether or not another job B exists in the queue. Where another job B exists in the queue, it is determined in S206 whether or not the job B is a job that uses the multi-purpose cassette 19. If the job B is a job that uses the multi-purpose cassette 19, it is determined in S208 whether or not paper that matches the paper information for the job B exists in the fixed-size paper supply cassette 18.

Abstract: In An image forming system having a plurality of printers and an image processing apparatus connected each other through a network, a printer to be sent a print job from the image processing apparatus is selected based on a degree of matching of a comparison between kinds of image size in the job and kinds of paper size installed in each printer.

Abstract: An image forming apparatus has a transfer unit for transferring image data to an image memory of a memory-incorporating apparatus via a network in response to a data transfer instruction, a reread unit for loading the image data stored in the image memory of the memory-incorporating apparatus in response to a data reread instruction, and an image output unit for outputting image data loaded by the reread unit. Thus, the image forming apparatus has the memory recall function without using an incorporated image memory.

Abstract: An image forming apparatus can carry out a continuous enlargement process by which an image of one original is enlarged and the image is formed on a plurality of sheets. According to the continuous enlargement process, a size of an original is first set, and a size of an image to be output can be input. A range of a size of an image to be output which can be input is calculated considering the size of the original and an ability of the apparatus. If the input size of the image to be output is within the range which can be input, a copy is made according to the continuous enlargement process. A user can input an arbitrary size within the range which can be input. Accordingly, the image forming apparatus can be provided which can form an image of an output size desired by a user when a size of an image of an original is to be changed and an image is formed on sheets of the number which is different from that of the original.

Abstract: In marker edition mode, characters such as a character line is read in a closed area on a document marked with a marker. Then, the image data is analyzed to decide image processing means for marker edition such as coloring. A rectangular area including the image is recognized as image processing area. Even if the image is included partially in the closed area marked with a marker, a rectangular area including the image wholly can be specified as image processing area.

Abstract: In a digital full color copying machine, one pixel on a photoconductor is divided into four subdivided small pixels. Functions a-d are assigned to each subdivided small pixel. Functions a-d are linear functions with density data as a parameter. The slope of functions a-d becomes smaller in sequential order. Exposure data of the four subdivided small pixels is calculated according to the density data of a pixel and functions a-d to expose each subdivided small pixel. A peak can be established in the exposure amount distribution to form a deeper latent image. Accordingly, resolution and graininess of the halftone area are improved.

Abstract: In order to improve operability of a copying machine which applies an image processing to an area of an original surrounded by a marker, following processes are carried out. An area of an original surrounded by a marker is detected. It is determined whether or not the number of the detected areas exceeds 30, or the time from starting of detection exceeds three minutes during the detection. If any of those two conditions is satisfied, edit based on the marker is not executed and image data which has undergone full-color copying is output.

Abstract: The present invention relates to an image forming apparatus for copiers, printers and the like. In the image forming apparatus, a standard pattern image, the density of which is detected by a sensor for controlling conditions of image forming operations, is formed on a photosensitive member. Density values are sampled at a plurality of sampling points on a standard pattern image by operating the sensor with a timing at which said sensor confronts said standard pattern image, and are mutually compared with each other. If the comparison result indicates that the timing of the sampling operation lags the standard pattern image, the sampling timing is corrected by eliminating the timing lag. The sampling operation of a subsequent sampling cycle is thereby conducted based on a corrected timing.

Abstract: A printer control unit carries out a predetermined calculation based on the amount of adhering toner detected by an AIDC sensor and the surface potential of a photoconductor detected by a V sensor to correct the light emission intensity of a light source to prepare light emission characteristic data for .gamma. correction to obtain an optimal image. A .gamma. correcting unit corrects an image signal output from an image signal processing unit using the calculated light emission characteristic data for .gamma. correction to control the light source to emit light based on the corrected data. More specifically, since the .gamma. correction data is obtained by calculation, optimal .gamma. correction can always be carried out without a memory of a large capacity.
