Canon LBP—800

在这一次的采购特集之中,虽然仪仅只有3款激光打印机,不过每一款产品都有其不同的定位以及功能.尤其在扩充规格以及附加功能上,彼此都有一段不小的差异.因此我们从规格表以及性能表等测试数据中的比较中,审慎选择出这一次的编辑推荐产品.在此次3款激光打印机中,HP LaserJet 2100在打印的品质上算是3款产品中最佳的,LexmarkOptra E31 2L在驱动程序的安装上相当的方便,在打印的速度上也相当的快.不过,在经过了整体性的评分之后,我们还是选择了Canon LBP-800这一款激光打印机,作为我们这一次激光打印机采购特集中的编辑推荐.

Canon: more than just concern

A profile is presented of Canon Inc., a Japanese company that has successfully diversified its product line away from the cameras with which it made its name. Among its products are digital color copiers, laser printers, and IC wafer-steppers. Canon, which operates six research centers in Japan plus R&D subsidiaries in the US and Europe, has grabbed 70% of the color printer market and is preparing for the evolution toward a new generation of G4 digital facsimile machines in conjunction with a more advanced integrated-services digital network (ISDN) infrastructure. Canon also has many new camera offerings, as well as a removable magnetooptical disk that offers read write, and erase capability, and can store 256 Mbytes, the equivalent of 6500 pages of text, on a single side     

Canography (Canon NP process) in electrophotography

A new system of electrophotography--the Canon NP process--is discussed. A photosensitive member comprising an insulating layer, a photoconductive layer, and a conductive layer is used in this process. The procedure for the formation of latent images consists of three steps: 1) primary charging, 2) image exposure with ac corona discharging, and 3) blanket exposure. The principle of image formation can be explained by a simple RC equivalent circuit representing the insulating layer, the photoconductive layer, and the air gap, etc. The influence of the thickness of the insulating layer on image quality can be represented by the response function of the NP plate. Sharpness and resolution calculated from the response function agree with the measured values. The NP plate has higher sensitivity than the conventional plate. This is explained by the fact that the electrostatic contrast required for development is obtained by a smaller amount of charge and that photoconductive layers of low resistance can be used. Since the NP process utilizes the injecting and rectifying properties of the photoreceptor, CdS or Se-Te alloys that are well known as one carrier photoreceptors can be used.     

Science For the Layman [review of The Canon: A Whirligig Tour of the Beautiful Basics of Science (Angier, N.; 2007)]

This ambitious, 304-page sprint through the fundamentals delivers its lessons via cheerful interviews with hundreds of top-notch scientists. However, the author's jittery style may alienate most people. The author, Natalie Angier, who reports on science for The New York Times, dips into physics, chemistry, and biology, and then on to rock formations and plants. She addresses the basic principles in each field, her chatty prose flipping between explanatory depth and comfortable imagery. Ultimately, the overlacking lack of focus robs readers of anything solid to clasp, and they are left itching for a more substantive narrative to connect the ample supply of colorful anecdotes. However, for those readers who are charmed by the Angier's freewheeling style, The Canon is one way to tickle the brain.
