An image forming apparatus includes an image forming device and circuitry. The image forming device forms an image on a recording medium, based on an image forming condition. The circuitry determines a position of the image formed on the recording medium by the image forming device, based on a detection signal of a pattern formed on the recording medium by the image forming device and reference position information of the pattern on the recording medium. The circuitry determines a reference position of the pattern differently depending on the image forming condition.

An image formation apparatus includes: an image former that prints an image on paper; a corrector that corrects a print position of the image on the paper; and a first sensor that is disposed on a conveyance path upstream of the image former, detects paper, and outputs detection data to the corrector, wherein the corrector obtains, on the basis of the detection data, an amount of change in a shape of first paper from a shape of second paper printed before the first paper is printed, and corrects a print position of a first image on the first paper on the basis of the change amount.

Provided is an image forming apparatus including a printer controller configured to form an image on a sheet, a storage unit configured to store a plurality of adjustment conditions for adjusting a position on the sheet at which the image is to be formed, and a CPU. The CPU selects one of the plurality of adjustment conditions, adjusts the position at which the image is to be formed based on the selected adjustment condition, and causes the printer controller to form the image on the sheet.

In an image forming apparatus that employs a laser scanning optical system that does not use an fθ lens, in the case where magnification correction by insertion/removal of an auxiliary pixel is performed based on the premise of digital PWM, an insertion/removal position of an auxiliary pixel is controlled in accordance with a purpose of each piece of image processing.

A method for feeding uneven media from a high capacity feeder includes rotating the pages in a stack 180° every 100-250 pages. This is only done with non-flat pages, such as, envelopes, pages with labels thereon, etc., which create tilted stacks and limit the number of pages that can be placed in the high capacity feeder. Rotating the pages 180° distributes the uneven build-up of the pages and creates a relatively flat stack, allowing the high capacity feeder to be filled to capacity. A camera or sensor placed in the high capacity feeder will detect the orientation of the stack on the fly so the image can be rotated accordingly.

The image forming apparatus includes a control unit for converting image information into an image signal and output the image signal with reference to a timing signal, a sheet feeding control unit for feeding a recording material, an image forming unit for forming the image on a photosensitive drum based on the image signal output from the control unit, a transmission unit for transmitting a length of the image corresponding to a length of an output period of the image signal, an automatic sheet length detection mechanism for acquiring a length of the recording material in a conveyance direction thereof, and an image control unit for controlling a time interval at which the timing signal is output based on the size of the image and the size of the recording material.

An image forming apparatus includes: an image forming unit configured to form an image on a continuous transfer medium on the basis of image data of a job; and a controller configured to manage the job and control the image forming unit, wherein the controller has a function of adjusting an image print position on the continuous transfer medium when a job medium width size specified in the job is different from a fed medium width size used in printing.

There is provided a printing control device. A setting unit sets a sorting priority mode that causes a printing device to perform printing using a recording sheet in which the difference from the recording sheet size designated by a current print job mounted on the printing device is within a predetermined range, in a case where a recording sheet with a same size as the recording sheet designated by the current print job is not mounted on the printing device, and a recording sheet which has a recording sheet size that is printable without reducing the printing range, and for which the difference from the size of the recording sheet designated by the current print job is within a predetermined range is mounted on the printing device in a sheet feed direction different from the sheet feed direction of the recording sheet of the previous print job.

The image forming apparatus includes a paper feed unit that stores print paper used for printing, a paper size sensor that detects a paper size of the print paper stored in the paper feed unit, a filter information setting unit that sets filter information indicating the paper size detected by the paper size sensor in association with the paper feed unit, and a paper catalog list generating unit that extracts a paper catalog matching the filter information from paper catalogs included in predetermined paper catalog data and generates a paper catalog list using the extracted paper catalog.

A printing system for printing on sheets of media having asymmetric media characteristics. A media transport system is controlled to pick a next sheet of media from a media tray. A detection system detects a media orientation of the sheet of media. A front end supplies image data having an orientation matching the detected media orientation, and a printing module prints the supplied image data on the sheet of media in accordance with the detected media orientation.
