Abstract: An image forming apparatus includes a first memory for storing image data, a second memory for storing image forming conditions, an image output unit for outputting the image data stored in the first memory under the image forming conditions stored in the second memory, and command means for generating a command of discarding the image data being output from the image output unit. The apparatus also has a controller. If a command of discarding the image data is generated by the command means, the controller discards the image data stored in the first memory, while it maintains the associated image forming conditions stored in the second memory.

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: 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: Image data transmitted from an image reading portion or a personal computer is once stored in an image storage portion. Then, an image region determining portion performs region determination of the stored image data. In addition, a toner consumption calculating portion calculates an amount of toner to be consumed required for outputting the image data. Image correction is performed in an image correcting portion according to a determined image region based on a result of comparison between the amount of toner to be consumed calculated and the remaining amount of toner measured. Image output is performed in an image printing portion based on the corrected image data. As a result, image degradation can be minimized and an output operation can be completed even when a remaining amount of a recording material becomes less than an amount required for image output.

Abstract: Job data is created by a personal computer 4. A display attribute and a program corresponding to the display attribute are attached to this job data. On the other hand, a received job is displayed on a screen of an operation panel of a digital copier 1. Whether or not the display attribute is attached to job data is determined in display processing of this operation panel. Then, if the display attribute is attached, the display screen is changed corresponding to the display attribute. This display attribute contains enlargement of a display content, change of display color and the like. If a function corresponding to the display attribute is not supported, a program attached to job data is executed. Consequently, there is provided a job information display apparatus, a job execution apparatus, a job instruction apparatus and a job processing system capable of changing the display screen depending on the display attribute of the job.

Abstract: An image forming apparatus provided with a function for binding a set of recording sheets by interposing said set of recording sheets between a folded cover sheet. When cover mode is set, the cover sheet is transported in a folding unit. The folding unit is controlled so as to fold said cover sheet into three sections of a front cover, spine and back cover. Content copy sheets are inserted in the folded cover sheet. The image forming apparatus is capable of cleanly binding documents even when the set of recording sheets is thick because the cover sheet can be folded in three.

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: 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: 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 such as digital copying machine can perform an operation to read the original document by an image reader and an operation to output image data stored in an image memory by a printer, independently of each other. A first timer measures a period of time that has elapsed since the suspension of reading of the original document by the image reader. A second timer measures a period of time that has elapsed since the suspension of output of image data stored in the image by the printer. The timers running independently of each other. Therefore even when one of the processes is continuing, if the other process is suspended due to either intentional discontinuation or an error, this other process may be cleared. As a result, an operator who wishes to input a job to the digital copying machine can learn the current status of each job residing in the digital copying machine.

Abstract: An image forming apparatus such as a copying machine which is capable of multi print job is disclosed, the image forming apparatus stores identification information of the recording sheet tray selected by a selection means for each registered print job in memory for each print job. When a recording sheet tray for a new print job is selected, selection of the recording sheet tray for the registered print job stored in memory is inhibited or a notice will be issued. Thereby, the recording sheet tray selected for the preceding print job will not be selected for the subsequent print job.
