Abstract:
A system and method to compensate for ghost appearances on a print due to a previous job, the method comprising defining areas in which ghosting is expected or detected and recording the image on a photoreceptor by selectively changing the parameters of the system as a function of position, to compensate for the effects of ghosting in ex-image and ex-nonimage areas.
Abstract:
A fuser stripping subsystem for use with a fusing system is provided. In one embodiment, at least one movable stripper finger is disposed adjacent a fusing assembly in a first position. Assuming a selected condition is met, the at least one movable stripper finger is moved from the first position to a second position for substantially aligning the at least one movable stripper finger with a toned image section of a print media sheet passing through a nip defined by the rolls. In another embodiment, a print media sheet with a toned image section is shifted, prior to feeding the same through the nip, so that the toned image section may be substantially aligned with at least one stripper finger. In yet another embodiment, a combination of stripper finger movement and/or image shifting may be used to obtain substantial alignment between one or more stripper fingers and an image.
Abstract:
Methods (300, 1000) of determining a light scattering property of a medium (152), are disclosed. The medium (152) is illuminated through a test pattern (e.g., 155, 510), the test pattern (155, 510) comprising at least one region containing a first pattern with substantial variation in two orthogonal directions at one scale. The test pattern (300, 1000) further comprises at least one other region containing the first pattern at a different scale. The light reflected from the illuminated medium (152) through the test pattern is measured to capture an image of the illuminated medium. A light scattering property of the medium (152) is determined based on the measured light.
Abstract:
A calibration method having the steps of: forming a test image on a sheet; reading the test image on the sheet; and determining correction data to converge data of the test image onto target data, based on information read in the reading step; wherein in cases where in the step of forming the test image a first test image is formed on a face of a transparent sheet as the test image, in the step of reading the test image the first test image is read from a first side of a face to be read which is opposite to the face of the transparent sheet where the first test image is formed.
Abstract:
An image forming apparatus has a latent image writing device that writes an electrostatic latent image on an image bearing member, a developing device that develops a toner image based on the electrostatic latent image, a transferring device that transfers the toner image onto a recording material, a position correcting unit that corrects a position of the electrostatic latent image written by the latent image writing device, a recording material determining unit that determines whether or not the recording material has a long width, and a corrected amount changing unit that, when the recording material determining unit determines that the recording material has a long width, changes an amount of correcting the position of the electrostatic latent image to a value different from a set value for a recording material having a standard width.
Abstract:
An image-forming system determines a type of paper for each single sheet in a job to determine whether it is prohibited to discharge a sheet to a finisher (step S12) to respond to diversifying demands to perform processes after printing using a plurality of paper types. However, the system allows paper to be included in a sheet bundle if the number of sheets is below a fixed limited number of sheets, even if paper types used are inappropriate for the finisher to be the discharge destination. (Steps S14, and Spaces 16) Therefore, discharge to the finisher is not rejected uniformly by the type of paper; finishing can be implemented after printing with a certain degree flexibility.
Abstract:
An image forming apparatus includes a toner image forming device for forming a toner image on a recording material with transparent or white toner. A fixing device fixes the toner image on the recording material. A fixed toner image detection device detects the toner image fixed on the recording material. A controller variably controls a toner image forming condition of the toner image forming device on the basis of a detection result of the fixed toner image detection device, which detects a glossiness of the toner image. The toner image forming condition, which is variably controlled by the controller, is a weight of the toner per unit area of the toner image on the recording material.
Abstract:
A method of printing comprising the steps of marking the surface of a test preprinted media with a first marking material; placing the media adjacent to a transfer media; disposing the test media and the transfer media into the nip of a fuser roller assembly to thereby apply predetermined heat and pressure thereto; removing the test media and the transfer media from the nip of the fuser roller after a predetermined time; and, measuring the density of the first marking material which has been offset to the transfer media.
Abstract:
An image-forming unit 100 in a complex device A forms a correction-use image onto a sheet in accordance with data, in such a manner that the correction-use image thus formed partly on and partly off the sheet and includes edges of the sheet, the date being preliminarily determined in accordance with a size of the sheet. An image-detecting section 520 reads that portion of the correction-use image which is transferred on an image-transfer belt 7 as the correction-use image is formed by the image-forming unit 100. A correction value is calculated in accordance with data thus obtained by the image-detecting section 520. A control section then causes a data storing section to store the correction value. The control section reads out the correction value when forming an image in the complex device A, and forms the image, performing correction of the image, using the correction value for correcting an image-forming condition regarding how the image is formed on the sheet. The image-forming condition, such as a position and a copy-scale, can be adjusted, even if using an unadjusted reading apparatus.
