Abstract: Where monochromatic pages (image data of monochromatic originals) and color pages (image data of color originals) are mixed in a print job received from a personal computer via a network includes and a distribution mode is set, a printer controller controls printing by distributing the monochromatic pages to a monochromatic image forming apparatus and the color pages to a color image forming apparatus. If the printing of the color pages by the color image forming apparatus is completed but the printing of the monochromatic pages is not completed, the mode of the color image forming apparatus is switched to a monochromatic mode and the printing of the monochromatic pages is distributed in accordance with the printing speeds (monochromatic printing) of the color image forming apparatus switched to the monochromatic mode and the monochromatic image forming apparatus.

Abstract: An image forming system has a color scanner; an image processing part for processing image data obtained by reading a document by use of the color scanner; and an image forming part for forming an image on the basis of image data processed by the image processing part, wherein the color scanner reads a first original which includes a portion of a character or diagram having a first color, and a portion which is marked in a second color different from the first color so as to cover information of the character or diagram, and the image processing part edits image data of the marked portion of image data of the read first original. The editing process includes a process for rectangularizing the marked portion, and a process for connecting the rectangularized regions when the rectangularized regions are close to each other.

Abstract: When a digital copying machine is switched on, a main CPU confirms whether the current timing is a timing at which an advertisement can be displayed on a display section. If operational inputs are being performed from the display section in the digital copying machine, the advertisement cannot be displayed and thus a normal image forming operation is controlled. If operational inputs are not being performed from the display section and the current timing is the timing at which the advertisement can be displayed, it is conformed whether an HDD stores a registered image as an advertisement image. If there is at least one registered image in the HDD, the at least one registered image is displayed on the display section at predetermined time intervals at the timing of the advertisement display in accordance with the priority level. The registered image in the HDD, whose remaining designated display time has reduced to zero, is deleted.

Abstract: A printer controller receives a printer job from external equipment and carries out the printer job using a printer. A user IF task accepts a reservation input for the use of a copying function using a scanner and the printer from a user while the printer job is being executed by the printer controller. Responsive to the copy reservation input, a job management task reserves the right of use of the scanner and the printer after the completion of the printer job in execution. If the printer is in operation when the user desires to use the copy function, the user is allowed to make a reservation for copying and then copy after the termination of the current printer job even if another printer job has been spooled.

Abstract: An image forming apparatus including CPU can eliminate an influence of a difference in access time by selecting a deletion mode of whether the image information of each page is deleted each time when printing of the page of the last copy of an original is finished or the image information of all the pages is in a lump deleted when printing of all the copies of the last copy of the original is finished in a sort mode according to whether or not a hard disk device is mounted when power is applied to the apparatus and enables at least an image information of a page read by a scanner to effectively create a file by generating near memory full in file creation of an image information, by switching possibility levels of concurrent operations of jobs based on the presence or absence of the hard disk device and a capacity of RAM.

Abstract: An image forming apparatus having at least one of a copying and printer functions, and a facsimile function, comprising means for inputting image data and size information of an image forming medium on which an image based on the image data is to be formed, means for accommodating image forming media having different sizes, respectively, means for forming an image, based on the image data input from the input means, on each of the image forming media accommodated in the accommodation means, means for detecting sizes of image forming media stored in the accommodation means, and means for switching, on the basis of a detection result of the detection means, between an image forming operation of the image forming means in the facsimile function and an image forming operation of the image forming means in the copying or printer function.

Abstract: An image forming apparatus having at least one of a copying function of forming an image represented by copy data, a facsimile function of forming an image represented by facsimile data, and a printing function of forming an image represented by print data, characterized by comprising means for acquiring the data, means for storing the data acquired by the data-acquiring means, means for registering image-forming commands for forming an image represented by the data stored in the storing means, means for selecting a plurality of image-forming commands registered in the command-registering means, one after another in a predetermined order, and means for forming images in accordance with the image-forming commands selected by the command-selecting means.

Abstract: An image forming apparatus including an ADF for automatically feeding a plurality of originals, a mechanism for selecting a continuous mode, in the continuous mode the plurality of originals separately fed by the ADF a plurality of number of times are processed as a series of originals, a mechanism for reading the images of the plurality of originals, a memory for storing as a series of images, the images read from the originals fed while the continuous mode is selected, and a printer for forming the series of images stored in the memory in a predetermined order.

Abstract: A mode for sorting sheets having two sides, on which images have been printed, is performed such that sheets each having one printed side are stacked in an automatic double side device, and the sheets stacked in the automatic double side device are sequentially extracted and conveyed. If a jam takes place during extraction and conveyance of the sheets, the position, at which the jam has taken place, is displayed on an LCD display unit. After the jammed sheet has been removed, the printing operation is caused to restart. If few sheets are stacked in the automatic double side device before the printing operation is completed, a copy key is depressed to perform control to perform the printing operation once again. Also, a method for replacing the images of the sheets which are jammed during the double sided copying operation is provided.

Abstract: An image forming apparatus and method for setting a binding margin. When a binding margin displayed on an LCD display unit of an operation panel has been set, a main CPU calculates a position, at which writing of the image of an original document starts, and magnification (an enlargement ratio or a reduction ratio) in accordance with a program stored in a ROM and to correspond to the binding margin and the size of sheets which are set by the LCD display unit and the size of the original document read by a scanner, and causes a printer to perform printing in accordance with a result of the calculation. When a binding margin has been set, the image of an original document can accurately be printed without loss of the image of an end portion of the image of the original document while maintaining the specified binding margin.

Abstract: A basic control portion stores image information read by a scanner in a page memory of a page memory portion through image processing means. When memory full takes place such that image information to be stored in the page memory is larger than the capacity of the memory in a case where a staple sorting mode has been set, the basic control portion suspends the staple mode and forms images in a set sorting mode by using image data stored in the page memory. As a result, even if memory full takes place in the staple mode, the image can normally be formed.
