Abstract: This invention provides a scanner, which is capable of scanning document images based on a stepping control table and a method to generate such a table. This scanner includes a scanning module to scan a document and generates a responding image signal, a stepping motor to drive the scanning module or the document and a control device to control the operation of the scanning module and the stepping motor. This control device includes a stepping control table, which contains the stepping numbers for the stepping motor to drive the scanning module or the document. While scanning a document, this device will accurately control the stepping motor according to the stepping numbers relating to the locations of the lines to be scanned, and further move the scanning module or the document to a pre-defined position for a scanning task. A design like this will reduce errors in a scanning module's movement caused by the mechanical deviation.

Abstract: A method and apparatus for reducing image unevenness due to light emission of a transfer element. Namely, when a printing speed is changed to 1/2n (n is a positive integer), a SLED head controller repeats a cycle to perform exposure control for one line and then stops the exposure control for the lines corresponding to 1/2n speed. For example, in the 1/2 speed (i.e., n=1), transfer and light emission driving are performed at an initially set maximum speed, and the cycle when the exposure control for one line is stopped after the one-line exposure control is repeated. The printing speed is changed on the basis of the type or kind of recording medium used.

Abstract: A scanning device includes a scanning mechanism, a memory, a processing mechanism, and a scan rate adjustment mechanism. The scanning mechanism scans a media sheet having an image thereon at a variable scan rate, to yield raw data. The memory temporarily stores the raw data. The processing mechanism converts the raw data within the memory into processed data. The raw data is removed from the memory as the raw data is converted. The scan rate adjustment mechanism adjusts the variable scan rate, based on one or more of an amount of free space within the memory, a fill rate at which the raw data is filling the memory, and a removal rate at which the raw data is being removed from the memory, so that the memory does not become completely full.

Abstract: An optical scanning unit used in an image forming apparatus having a latent image carrier includes a light emitter, a rotary deflector, an inclination adjustment unit, and a controller. The light emitter emits a light beam. The rotary deflector deflects and scans the light beam onto a surface of the latent image carrier. The inclination adjustment unit adjusts an inclination of a scan line corresponding to the light beam relative to a reference scan line on the latent image carrier. The controller changes at least one of a linear velocity of the latent image carrier and a rotation speed of the rotary deflector so as to change a ratio between the linear velocity of the latent image carrier and a scan speed of the light beam, and controls the inclination adjustment unit based on the ratio to keep the scan line from inclining relative to the reference scan line.

Abstract: A film scanner performs a main-scan of a film by an imaging device and performs a sub-scan of the imaging device so as to enable scanning at any resolution using a simple configuration. The scanning mechanism, for the sub-scan of the film with respect to the imaging device, has a transport table for supporting the film held by a film holder and transporting it in a sub-scan direction and a transport mechanism for moving the transport table in the sub-scan direction. The source of the drive power of the transport mechanism is a scan motor (stepper motor) driven by a pulse signal output from a motor drive circuit. The motor drive circuit is configured to enable micro-stepping of the scan motor.
