摘要： An apparatus and method for ink-jet printing onto an intermediate drum in a helical pattern while correcting for image skew and aliasing. A plurality of ink-jet print heads place an image on an intermediate drum, impervious to ink, in a helical patter. To compensate for helical printing, the image is altered by nozzle placement and image manipulation to correct for skewing errors, and thereafter, the nozzle timing is adjusted to correct for aliasing. The plurality of print heads move parallel to the axis of rotation of the drum while the drum is simultaneously rotating, causing the image to be placed in a helical pattern. Once the entire image is placed on the drum, paper is rolled against the drum under pressure and the image is transferred thereto.
摘要翻译：一种用于在校正图像偏斜和混叠的同时以螺旋图案在中间滚筒上喷墨打印的装置和方法。多个喷墨打印头以螺旋图案将图像放置在不透墨水的中间滚筒上。为了补偿螺旋印刷，通过喷嘴放置和图像操作改变图像以校正偏斜误差，此后，调整喷嘴正时以校正混叠。多个打印头在滚筒同时旋转的同时平行于滚筒的旋转轴线移动，从而使图像以螺旋状的方式放置。一旦将整个图像放置在滚筒上，纸张在压力下滚动滚筒并将图像转印到其上。

摘要： A scanning system for a printer or scanner that has a beam source that produces a light beam at a point of origin and has a scanning mirror that sweeps the light beam from a position “A” to a position “B.” A lens receives the light beam from the scanning mirror and directs the light beam as a scanning beam to an image plane surface. A first synchronizing mirror intercepts and reflects a light ray to a photo detection system when the scanning beam is at a position “A′” that is in the vicinity of position “A” and between position “A” and “B”. A second synchronizing mirror intercepts a light ray when the scanning beam is at a position “B′” that is in the vicinity of position “B” and between position “A” and “B”, and reflects the light ray to a folding mirror that reflects the light ray to the photo detection system. In some configurations two photo detection systems are used in lieu of the folding mirror. In some instances, the lens is a focusing lens and when the scanning beam is at position “A′” and when the scanning beam is at position “B′”, equal optical path lengths are established between (1) the point of origin and the photo detection system and (2) the point of origin and virtually to the image plane surface such that the light ray arriving at the photo detection system is well focused.
