  • Patent number: 8422072
    Abstract: An image forming system capable of shortening the time required to process configuration information on an image forming system and shortening communication time. When any of sheet processing apparatuses is activated before activation of an image forming apparatus, a controller of a sheet processing apparatus acting as a sub-manager configures a sub-system consisting of sheet processing apparatuses connected to a communication network and creates configuration data on the sub-system. When recognizing that the image forming apparatus is newly connected to the network, the sub-manager apparatus notifies the image forming apparatus of the already created configuration data based on which a controller of the image forming apparatus creates configuration data on the system and stores it into a RAM.

  • Patent number: 8180243
    Abstract: There is provided an image forming system that are capable of preventing a user or operator from forgetting to carry out a maintenance operation based on required sub-maintenance items after execution of a maintenance operation based on an associated maintenance item, such as component replacement, cleaning, or adjustment. A table of maintenance items and sub-maintenance items associated with respective ones of the maintenance items is stored in a ROM. When a CPU determines that a maintenance operation based on a selected one of the maintenance items has been completed, the CPU determines whether or not there is any sub-maintenance item associated with the selected maintenance item, by referring to the table. When it is determined that there is one or more sub-maintenance items associated with the selected maintenance item, a CPU provides control to display the sub-maintenance item or items in an operating/display unit.

  • Patent number: 8059976
    Abstract: After the start of an image formation operation, feeding of a sheet on which an image is to be formed is started, and an image formed on an image carrier is transferred onto the fed sheet. On the other hand, after the start of the image formation operation, in a case that the sheet has not been detected within a predetermined time period in a predetermined position on the upstream side of a transfer position, transfer is stopped, and after the stoppage of the transfer, re-feeding of the sheet is performed. By the re-feeding, in a case that the sheet has been detected in the predetermined position, formation of an image to be transferred onto the sheet is started, then the timing of start of the feeding of the sheet is delayed from the timing of start of the feeding in normal times.

  • Patent number: 8055179
    Abstract: An image forming apparatus capable of efficiently performing an image forming processing even in a case where a post-processing apparatus performs a post-processing during a both-sides printing. A first time period needed by a first both-sides image forming processing and a second time period needed by a second both-sides image forming processing are computed in a case where a post-processing unit performs a post-processing on a recording sheet formed images on both sides thereof. The first time period and the second time period is compared, and any one of the first both-sides image forming processing and the second both-sides image forming processing is selected based on the comparison.

  • Patent number: 7983584
    Abstract: An image forming apparatus in which surplus tabbed sheets produced in one set of output can be utilized for the next set of output, without requiring a user to perform a laborious task. In the image forming apparatus, a CPU calculates the number of tabbed sheet groups which will be used for one set of image formation and the number of tabbed sheets which will be used from among the last tabbed sheet group. Among the last tabbed sheet group, surplus tabbed sheets which will be left unused in the one set of image formation are determined. If the number of tabbed sheets is equal to or less than the number of the surplus tabbed sheets, at least one of the surplus tabbed sheets is used to carry out two sets of image formation.

  • Patent number: 7900918
    Abstract: A sheet conveying system in which when a sheet is passed from a sheet conveying apparatus to another, each including a sheet conveyance controller, the receiving apparatus can smoothly control acceleration, deceleration, or stop of conveyance of the sheet. A first sheet conveying device includes a first conveying roller pair to nip and convey a sheet, a releasing mechanism to release nipping of the sheet by the first conveying roller pair, and a first controller to control the first conveying roller pair and the releasing mechanism. A second sheet conveying device includes a second conveying roller pair to nip and convey the sheet conveyed by the first sheet conveying device, a second controller to control the second conveying roller pair, and a detecting device to detect position of a sheet. In response to the detection by the detecting device, the second controller causes the releasing mechanism to release the nipping of the sheet by the first conveying roller pair.

  • Patent number: 7734201
    Abstract: This invention provides an image forming apparatus capable of shortening the user's print waiting time as much as possible when it is determined that image adjustment is necessary during the image forming operation, and a control method therefor. To accomplish this, in a color image forming apparatus including a plurality of image forming stations which form toner images with a plurality of toners on the basis of a job, it is discriminated whether adjustment processing is necessary during a continuous image forming operation based on the job. If it is discriminated that adjustment processing is necessary, it is determined whether each of the image forming stations has a non-operating time enough to execute the discriminated adjustment processing during the image forming operation. The image forming station determined to have a non-operating time enough to execute adjustment processing executes the discriminated adjustment processing during the non-operating time.
