    • A raster scanner with laser for generating a scanning beam and compact, folded optical system for transmitting the beam to the object to be scanned. The optical system includes a modulator for modulating the beam in accordance with video image signals and a rotatable polygon for scanning the beam across the object to be scanned. The laser is supported at one end in a spherical bearing, permitting rotation of the laser about a point coincident with the optical axis of the scanner and at a second remote end by screw type adjustors which are used to adjustably displace the laser about the pivot point and so align the axis of the laser beam with the optical axis of the scanner. Scanner operating circuits are provided including a circuit enabling one or both of the scan detectors to serve as a light meter when aligning the laser.
    • 一种具有用于产生扫描光束的激光光栅扫描器和用于将光束传输到待扫描对象的紧凑折叠光学系统。 光学系统包括用于根据视频图像信号调制光束的调制器和用于扫描横过待扫描对象的光束的可旋转多边形。 激光器在一端支撑在球面轴承中,允许激光器围绕与扫描仪的光轴重合的点旋转,并且在第二远端由螺旋型调节器旋转,螺旋型调节器用于可调节地使激光绕枢轴点移位 并使激光束的轴与扫描仪的光轴对齐。 提供了扫描器操作电路,其包括使得一个或两个扫描检测器在对准激光器时用作光度计的电路。

    • An electrostatographic processor having a rotatably driven drum for advancing an imaging surface through successive processing stations, a development system charged with a ferromagnetic developer for developing latent electrostatic images carried by the imaging surface, and a cleaning system including a sump for collecting residual toner removed from the imaging surface is equipped with a toner reclaim system comprising a plurality of permanent magnets which are mounted at spaced apart intervals on one end of the drum to magnetically convey developer from the development system to the cleaning system sump via one non-magnetic conduit and from the cleaning system sump back into the development system via another non-magnetic conduit. The developer blends with the residual toner while passing through the sump of the cleaning system, with the result that its toner concentration tends to increase, thereby causing residual toner to be mechanically and triboelectrically returned to the development system.
