摘要： A method of correcting output image squareness in a laser printer system having a Raster Output Scanning (ROS) device with a pivotal mounting. The method includes printing a test pattern that includes a plurality of markers printed in a predetermined geometric arrangement and calculating a skew angle based on the measured distances, preferably using the Law of Cosines. The ROS device is then automatically rotated by an amount sufficient to correct the skew angle. The ROS rotation is performed automatically by an adjustment system connected to the ROS. The method optionally includes a scanner for scanning the test pattern image and making the measurements automatically via a program configured to analyze the scanned image.

摘要： A mirror attachment structure for an image-reading apparatus that includes a carriage for mounting a light source for illuminating a document and a photoelectric conversion device for receiving light from the document includes a reinforcement sheet metal member. The reinforcement sheet metal member includes first and second sections that do not lie in the same plane and a mirror that is fixed to one of the sections. The carriage supports the reinforcement sheet metal member. The reinforcement sheet metal member may be formed into a proper shape by bending. The mirror may be directly bonded to the reinforcement sheet metal member, mounted on a support attached to the reinforcement sheet metal member, or formed directly on the reinforcement sheet metal member by evaporating aluminum onto the reinforcement sheet metal member.

摘要： A xerographic marking device includes a source of pixels representative of digitized image information. A rendering image processor analyzes the pixels for an image characteristic, and based on the analysis assigns one of at least three values to each pixel. The three values are selected from a set of values representing positive, negative or neutral relative to a predetermined exposure bias. The device also includes an imaging output device which converts the values assigned to the pixels into areas of selective exposure on a charge retentive surface. A charge on the charge retentive surface such as a photoreceptor accordingly, includes an area of positive charge determined to electrostatically react with a charged monochrome marking agent or toner in a first manner, for example by attraction. The charge also includes a negative charge area which is determined to electrostatically react with the toner in an opposite manner, for example to repel toner. Optionally, the charge also includes an overshoot or super positive/super-negative area. The overshoot areas have stronger electrostatic reactions with the toner than their corresponding positive/negative charges.

摘要： An image reproduction engine which causes toner to adhere to a development region of certain area located at a certain position within dots according to image reproduction data is utilized for image processing, wherein a halftone is expressed by means of halftone spots formed from a plurality of dots. The centroid of the halftone spot formed from a single dot or a plurality of adjacent dots is shifted from the center of the dot to an arbitrary position, thus achieving desired screen angles or desired pitches of halftone spots. As a result, screen angles related to an irrational tangent can be realized, and the pitches of halftone spots of a plurality of color screens can also be made uniform. 31.
