摘要： An original-feeding device includes an original tray, a pickup roller configured to be lowered onto originals stacked on the tray and to feed one of the originals, the pickup roller configured to be lifted up after the feeding, a conveyor configured to convey the fed original, a length detector configured to detect a length of the conveyed original, an original sensor configured to detect a trailing edge of the conveyed original, and a controller configured to control the pickup roller either in a first mode in which the pickup roller is lowered in accordance with a detected length of the original or in a second mode in which the pickup roller is lowered at the detection of a trailing edge of the original. The controller changes the first mode to the second mode if lengths of the originals detected by the length detector vary.

摘要： PROBLEM TO BE SOLVED: To provide an image reader which reads an image with excellent image quality without delaying an initial operation when performing next reading operation using a reading unit that has not been used in the last reading operation. SOLUTION: A controller 400 instructs dust avoiding operation to a reader section 200 during job execution (S6) and the reader section 200 performs the dust avoiding operation between paper sheets. When the end of the job is detected, the controller 400 instructs the dust avoiding operation to both the reader section 200 and a document rear-side reading section 17 that has not been used (S8), and the reader section 200 and the document rear-side reading section 17 perform the dust avoiding operation. Furthermore, the controller 400 instructs shading correcting operation to both the reader section 200 and the document rear-side reading operation 17, and the reader section 200 and the document rear-side reading section 17 perform the shading correcting operation.

摘要： PROBLEM TO BE SOLVED: To efficiently control an image forming condition utilizing a reference image based on a state of a recording part such as residue quantity of recording material of each color. SOLUTION: In this device, the residue quantity of color toner and black toner provided in an image forming part 203 is detected by a DC controller 202 and when the toner is finished, that is notified to a reader controller 106. Ability for monochrome and/or mono color image formation is displayed by a reader controller 101 when no toner is notified to it and a host computer 210 is notified through a printer controller 207.

摘要： An image reading apparatus that, in a case where the light amount of light illuminated from an image reading lamp has decreased, maintains the quality of a read image without decreasing productivity, and a method for controlling that image reading apparatus, are provided. To accomplish this, this image reading apparatus is provided with RGB line sensors that read a color image, and a monochrome line sensor that reads a monochrome image and has a faster horizontal transfer speed than the RGB line sensors. Further, this image reading apparatus reads a monochrome image using the RGB line sensors even in a monochrome mode in a case where the light amount of the lamp for illuminating an original decreases and so an output level for reading an image with good quality cannot be obtained from the monochrome line sensor.

摘要： An image forming apparatus that is capable of carrying out image formation on a recording medium such as plain paper without increasing the FCOT (First Copy Out Time) and is also capable of carrying out optimal image formation on a recording medium, such as thick paper, for which the processing speed is reduced with no registration misalignment between the leading ends of toner images and the leading end of the recording medium. An image is primarily transferred onto a rotatively driven image carrier, and the image on the image carrier is secondarily transferred onto a recording medium. An image writing reference position signal for starting image formation is issued based on the circumference of the image carrier which is the length of the image carrier in the direction of rotation thereof or based on a detected reference position on the image carrier. A user can selectively switch, through operation of an operating section, between the issuing of the image writing reference position signal based on the circumference of the image carrier and the issuing of the image writing reference position signal based on the detected reference position.

摘要： PROBLEM TO BE SOLVED: To solve the problem of a paper feeding failure caused that the rise of a document tray does not follow control, when starting a job by fully loading documents on a document tray of a document reader. SOLUTION: When starting the job in a state of loading the documents on the document tray in an ordinary loading quantity, the document tray is lifted by driving a lifter motor by a predetermined quantity after detecting reduction in the documents. While, when starting the job in a state of fully loading the documents on the document tray, only when the first document tray rises, the document tray is lifted until a lower limit detecting sensor is turned off.

摘要： PROBLEM TO BE SOLVED: To provide an image reading apparatus which can improve user's operability and can shorten a FCOT (First Copy Output Time) when reading an image. SOLUTION: When it is detected that a pressure plate 210 transits from an open state to a closing starting state by sensors 213, 214, a lamp 203 is lit and when a certain operation instruction is input from an operation part 235 by the time original size is fixed, a lighting state of the lamp 203 is maintained even after the pressure plate 210 is closed.
