There is described an image outputting system including a controlling apparatus and an image outputting apparatus. The image outputting apparatus is provided with an inputting unit to input a change instruction with respect to the print products and a setting-change instructing unit to transmit the change instruction to the controlling apparatus, when the change instruction, inputted from the inputting unit, includes a change of the setting information. The controlling apparatus is provided with a first changing unit to rewrite the setting information attached to the first-type image data being an object of the change instruction, based on the change instruction when receiving the change instruction and an image develop processing section to convert the first-type image data, being an object of the change instruction, to the second-type image data, based on the setting information rewritten, and to send the second-type image data to the image outputting apparatus.

Image outputting system

An image forming apparatus includes a sequence memory to store a sequence of an initialization processing to be conducted only at an installation of the apparatus, an adjuster to adjust the apparatus in accordance with the initialization, an apparatus status indicator to indicate whether the apparatus is new or not. The apparatus further includes a controller so that the adjuster adjusts the apparatus on the basis of the status of the indicator. A judging device judges whether to continue or stop the initialization process on the basis of a predetermined state of the apparatus such as whether a process unit is new or old or whether a cover is attached to a photoreceptor or not.

An image forming apparatus includes a process unit provided detachably attachable to the apparatus; a driving source provided inside the apparatus and outside the process unit; a power transmitter to transmit a driving force from the driving source; a rotary member provided inside the process unit, the rotary member being rotated by the driving force from the driving source transmitted through the power transmitter. The apparatus further includes a detector to detect a state of rotation of the rotary member, and to output a signal corresponding to the state of rotation of the rotary member; and a judging member to judge a rotation abnormality of the rotary member on the basis of the signal output from the detector.

Rotation abnormality detecting device for use in image forming apparatus

An image forming machine, such as a copier or a printer, for forming a toner image on a recording sheet includes a developer for forming a toner image on a photoreceptor, the photoreceptor holding the toner image on its surface; a transfer device for transferring the toner image onto the recording sheet; a light emitting device for irradiating a light beam onto the surface of the photoreceptor; a light receive for detecting a reflection of the light beam from the surface of the photoreceptor, and for generating a variable detection signal according to an amount of the reflection of the light beam; a first comparing circuit for comparing a value of the variable detection signal with a first predetermined threshold value, and for generating a first comparison signal; a first judgment circuit for determining whether or not a sheet wrapping jam of the recording sheet on the photoreceptor occurs according to the first comparison signal; a first memory for storing the value of the variable detection signal when the first judgment circuit determines that the sheet wrapping jam occurs; a first calculation circuit for calculating a second threshold value according to the value of the variable detection signal stored in the first memory; a second comparing circuit for comparing the value of the variable detection signal with the second threshold value, and for generating a second comparison signal; and a second judgment circuit for determining whether or not a sheet wrapping jam of the recording sheet on the photoreceptor is solved according to the second comparison signal.

Image forming apparatus with a sheet wrapping detection apparatus

An electrophotographic copying machine capable of inserting an inter-sheet in a copy of a document. A width-detector is provided to detect the width of an inter-sheet contained in an inter-sheet tray. A judging circuit determines if the detected width of the inter-sheet is within an allowable width range. If the detected width is not within the allowable width range, the inter-sheet is inhibited from being fed and reminder information is displayed. If the inter-sheet is required to be blank with no image of the original recorded thereon, an automatic document feeder is controlled so as to stop feeding the original sheet while the inter-sheet is conveyed to be placed at the insert-page. The adjustment of copy image density, including scanning of the original sheet, is also stopped.

Copier with automatic insert feed having an interrupt function

A copying apparatus includes an automatic document feeding unit for sequentially circulating and feeding documents to be copied, an image forming unit for forming images on the documents on both surfaces of each copying paper sheet by an electrophotographic process, a punching/binding unit for punching or binding a plurality of copying paper sheets subjected to image formation, an image shift unit for controlling a paper feed timing of a copying paper sheet with respect to a formation position of a document image, and a control unit for causing the image shift unit to perform image shift when even-numbered pages of documents are copied.

Copying apparatus

An electrophotographic copying apparatus is equipped with an automatic document feeder and an optical system for exposing a document by scanning. The automatic document feeder feeds and places the first original document on a platen glass table where the first document is exposed to light. The optical system exposes the first document by scanning light subsequent to a preliminary movement of the optical system. The automatic document feeder replaces the first document with the second original document, while delivering out the first document, wherein replacing the first document with the second one during the period while the optical system is carrying out the preliminary movement after exposure of the first document.

Method of operating an electrophotographic copying apparatus wherein

An image processing apparatus includes a photoelectric converter, a multiple-value circuit, and a detachable external storage unit. The photoelectric converter photoelectrically coverts data of an original into image signals. The multiple-value circuit converts the image signals into multiple-valued data by comparing the image signals with predetermined threshold value data. The detachable external storage stores the threshold value data. The threshold values can also be made automatically responsive to gray scale data. The automatic mode and the manual selection mode are switched between in response to a release (toggle) signal. Color separation and color ghost correction are provided; and various types of formatting management are faciliated. Partial color converting (as, for example, color reversal) is also provided.

Digital multiple-color image processing apparatus

An electrophotographic copying apparatus has increased speed in recording sheet conveyance where the conveying path from the sheet feed cassette to the photosensitive member is relatively long. The sheet conveyance apparatus is constructed to equalize the line speed of the photosensitive member, the feed speed of the recording sheet and the conveying speed of the recording sheet. A plurality of sheets serially fed out from a sheet tray are concurrently transported along the sheet path. A sheet is fed out from the sheet tray in response to a timing reference signal generated in response to the scanning operation for a previously fed out sheet.

Sheet conveyance apparatus

A copying apparatus which performs either of two scanning functions depending on the size of original documents. In case of a large-size document, a scanning operation therefor is carried out by moving the document relative to the stationary fixed optical system responsive to selection of such scanning operation. The selection is effective only when the large-size document is detected.
