Abstract:
An image forming apparatus which can improve image formation capability to a satisfactory degree while curbing the rise in running cost. An image forming device forms adjustment images having different densities on an image support member having a higher optical reflectivity than an optical reflectivity of the adjustment images. A reading reads the adjustment images. An output from the reading device is read at a predetermined number of readings or time interval between readings based on the densities of the adjustment images susceptible to the optical reflectivity of the image support member.
Abstract:
A program operating apparatus is provided, which is capable of rewriting control programs for a plurality of CPUs without using any exclusive external apparatuses, thereby achieving a simplified and efficient rewrite operation. A control program stored in a ROM of a master CPU that controls the basic operation of the entire apparatus is transferred to a slave CPU and then written to an internal ROM of the slave CPU which controls the operations of functional units of the apparatus. The transfer of the control program is carried out when the mode of the apparatus is switched to a write control mode.
Abstract:
A plurality of subsystems having diverse individual functions can be connected to an image forming apparatus. Each of the subsystems is made up of, for example, plural kinds of units which are different in performance from each other. Each of the units has inherent information related to the performance, and decides the operation specification of the entire image forming apparatus according to the combination of those units.
Abstract:
A technique for reducing downtime that accompanies the execution independently of adjustment processing for maintaining image quality and the execution of finishing processing relating to a printing medium. In order to apply the finishing processing to the printing medium in a finishing processing unit, an image forming apparatus to which this technique is applied sets a time between sheets that extends from end of image formation regarding a first sheet of the printing medium to start of image formation regarding a second sheet of the printing medium transported following the first sheet of the printing medium in the image forming unit, and executes adjustment processing, which is for maintaining image quality in the image forming unit, within the set time between sheets.
Abstract:
Disclosed is an image forming apparatus whereby waiting time (downtime), which is required for forming an image by automatic adjustment relating to image formation density or image formation position, is made shorter than in the prior art. When an image having a size equal to or less than a prescribed size is formed is formed in this apparatus, the image to be formed is placed on an image carrier in such a manner that a vacant area for forming an adjustment pattern can be reserved on the image carrier. As a result, automatic adjustment relating to image formation density or image formation position can be executed while an image is formed.
Abstract:
There is provided a punching device including: a die member having a plurality of die holes formed therein; a plurality of punch members which are caused to advance into the die holes to punch holes in a member to be punched; an operating member having cam portions formed along a direction intersecting the direction of advancement of the punch members, the operating member being moved along the direction intersecting the direction of advancement of the punch members to cause by a conversion function of the cam portions the punch members to advance into the die holes; and a drive unit for selectively causing advancement of the plurality of punch members by changing the direction of movement of the operating member. In the punching device, each of the cam portions has a straight groove and a cam groove for performing the conversion function, and when the operating member is moved in one of opposite directions, at least one of the cam grooves of the cam portions acts on one of the punch members to selectively cause the same to advance.
Abstract:
An image forming system that makes it possible to open or remove an external cover of an apparatus to perform maintenance on the apparatus even while the system is operating. Out of a plurality of conveying paths, at least one conveying path for which at least one part related to the conveying path can be subjected to maintenance is determined, in accordance with a type of the image forming process being executed. The conveying path for which it has been determined that the part related to the conveying path can be subjected to maintenance is displayed on a display device.
Abstract:
In an image formation system which includes a finisher with an inserter having a tray for stacking the specific sheet on which an image such as a cover image was formed, and an image formation apparatus, a series of originals composed of plural pages is read from its head page in due order, the image based on the read original is formed on the sheet, the sheet stacked on the inserter is fed, the sheet from the inserter is reversed to set its image-formed face facedown, the sheet from a printer unit is reversed to set its image-formed face facedown. The sheet, the image-formed face of which was reversed facedown, is discharged from the printer unit to the finisher and, on the finisher, the sheet from the inserter is stacked as keeping its image-formed face facedown and the sheet from the printer unit is stacked as keeping its image-formed face facedown. The top and bottom of the image formed by the image forming apparatus corresponds to the top and bottom of the insert sheet.
Abstract:
An entrapment detection device of an opening/closing member which efficiently performs an entrapment determination and restrains an entrapment load even when a motor rotational signal is not inputted. The entrapment detection device includes a controller for performing the entrapment detection based on detected motor rotational signal cycle changes outputted from a motor rotation sensor which is synchronized with the movement of a motor for actuating an opening/closing member. The controller stores the cycle changes of a predetermined number of output pulses from the sensor, predetermines a standard cycle time Tb from the stored pulse output, and calculates a cycle coefficient of the entrapment. When the motor rotational speed is reduced, an entrapment detection operation is performed by comparing a value of time from a previous cycle change to a current cycle change multiplied by the calculated cycle coefficient with the standard cycle Tb.
Abstract:
It is intended to obtain outputs of insert sheets suitable for an inserter without delay. Thus, it is controlled to sort sheets on which pages of an image, being the print object in a mode to output the sheets to be set to an inserter provided in another apparatus having such the inserter, of first type in a series of images having plural pages were formed respectively, on the basis of information based on the inserter provided in the another apparatus.
