Abstract: Conventional analog front ends or AFEs for scanners are implemented using multiple integrated circuits or ICs. As a result, there is typically a problem of skew (due at least in part to manufacturing process variations) for these different ICs in the AFE. Here, an AFE is provided which serializes input data so as to compensate for skew.

Abstract: A method and apparatus for detecting roller eccentricity in a CIS scanner is disclosed. An image of a target is captured using the CIS scanner. The image of the target is analyzed for periodic horizontal banding. The period of the periodic horizontal banding is compared with the circumference of a pressure roller in the CIS scanner. When the period matches with the circumference of the pressure roller, an error is set.

Abstract: An image reading apparatus is provided with a carriage accommodating an optical unit for image reading, a driving member for moving the carriage, a guide rail, a guide-rail engaging portion engaged with the guide rail, a holding portion for holding the driving member, a guide plate and a claw portion. The claw portion presses the guide-rail engaging portion against the guide rail by partially deforming the driving member to produce a tensile force in the driving member and causing the tensile force to act on the first end portion of the carriage, and produces such a rotation moment for biasing the first end portion of the carriage in a first direction parallel with a sub scanning direction and, on the other hand, biasing the second end portion of the carriage in a second direction opposite to the first direction and parallel with the sub scanning direction.

Abstract: Motion is introduced into a scanning operation, in addition to the motion that is inherent in any scanning operation. For example, in a flatbed scanner a linear array of scanning devices is positioned across a document in a first or “x” direction and this array is moved across the document in a perpendicular or “y” direction. With embodiments of the present technology a vibratory motion is introduced into the scanning process—not aligned with the basic “y” direction of scan. Such vibratory motion can be controlled in accordance with pre-stored data, or a random process can be employed. In some arrangements, the vibration reduces Moiré patterns. In other arrangements, the vibration causes a hidden pattern to be revealed from the scanned object. A great many other features and arrangements are also detailed.

Abstract translation: 除了任何扫描操作中固有的运动之外，还将运动引入扫描操作。 例如，在平板扫描仪中，扫描装置的线性阵列沿着第一或“x”方向跨过文件定位，并且该阵列沿垂直或“y”方向移动穿过文件。 利用本技术的实施例，将振动运动引入扫描过程 - 不与扫描的基本“y”方向对齐。 这样的振动可以根据预先存储的数据进行控制，也可以采用随机过程。 在一些布置中，振动减少了莫尔图案。 在其他布置中，振动导致从被扫描物体露出隐藏图案。 还有很多其他功能和安排也很详细。

Abstract: A laser scanning assembly generates a laser beam and scans the laser beam through a plurality of scan lines to form desired dots. Each scan line is positioned to overlap an adjacent scan line and each dot includes a plurality of segments. The scanning assembly scans the laser beam through multiple scan lines to fully discharge each segment of each dot. The laser scanner assembly would typically be part of a laser printer.
