The system monitors the number of sheets that should be housed in the finishing tray based on the information from the copying machine, the output from the sensor located on the sheet conveyance path to the finishing tray unit and the signals that indicate ejection of the sheets from the finishing tray. When jam correction is performed, the system determines the number of sheets for which image formation should be re-performed in accordance with the output from the finishing tray paper detection sensor.

Image forming system having job recovery depending on number of sheets in ejection tray

An image processing apparatus for forming an image on the basis of density data of respective picture elements corresponding to an original image, which includes a first memory for storing density data of the respective picture elements obtained by reading the original image, a multiline screen processing processor for processing the stored density data to add at least a part of density data of one of adjacent picture elements to that of another one, and a second memory for storing the processed density data. An image is formed by a printer on the basis of the density data stored in the second memory.

Image processing apparatus shifting image data between adjacent picture elements

The image editing apparatus of the present invention reads text image having a plurality of character line image along to a predetermined direction, makes histogram expressing the distribution characteristics of said text image, detects said character line image having a predetermined size based on said histogram, and performs editing process for said character line image having said predetermined size.

Image editing apparatus

The temperature and humidity around a photoreceptor drum and the total number of copied sheets of the photoreceptor drum are detected. Data LDATA for setting the intensity of a laser beam and data BDATA for setting the beam diameter according to the detected results are provided from an image control circuit to a laser drive circuit and a collimator lens drive circuit. The laser drive circuit corrects the intensity of the laser beam output from an LD package according to LDATA, and the collimator lens drive circuit controls the position of the collimator lens according to BDATA to correct the beam diameter of the laser beam.

Image forming apparatus having circuits for adjusting light beam

A single-scan, multi-color image forming apparatus includes a document support for the support of an original document and a scanner, including a light source that is supported for movement from one end of the document support toward the opposite end for scanning successive incremental areas of the original document placed on the document support. An editing lever is supported for movement along one side of the document support in a direction conforming to the direction of movement of the scanner. An image forming device forms, on a single copying sheet, images of portions of the original document, which are positioned upstream and downstream of the editing lever with respect to the scanning direction, in first and second colors respectively. Also, a control unit controls the exposure made by the scanner.

Single scan, multicolor imaging forming apparatus capable of adjusting

A copying apparatus including a recording module for forming an image on copy paper sheets fed from a sheet feeding portion and discharging the copy paper sheets to a sheet ejecting portion and a sheet processing module mounted detachably on the sheet ejecting portion. The sheet processing module includes a sheet cassette mounted detachably on the sheet processing module and the sheet feeding portion, a copy receiving tray and a changeover device for changing over to the sheet cassette or the copy receiving tray, a passage of the copy paper sheets discharged from the sheet ejecting portion.

Copying apparatus having a sheet refeeding device

A copying apparatus including a recording device for forming an image on copy paper sheets fed from a sheet feeding portion and discharging the copy paper sheets to a sheet ejecting portion, a sheet cassette mounted detachably on the sheet ejecting portion and the sheet feeding portion, a copy receiving tray, a mode selecting device for selecting first and second modes for accommodating the discharged copy paper sheets in the copy receiving tray and the sheet cassette, respectively, a cassette detecting device and a control device for controlling the mode selecting device in accordance with detection states of the cassette detecting device.
