    摘要： When cover (8) of the laser printer (3) is closed, absence of the replaceable cartridge (15) or the shroud assembly (9) will activate both an electrical and a mechanical interlock. A moveable switch actuator (16) on the shroud assembly will be absent if the assembly is omitted and will not find a guide ramp if the cartridge is absent, thereby assuring power to the light source remains off. A shutter (13) also blocks the normal light path and is moved aside by a pin (14) on the cartridge, and therefore blocks light unless a cartridge is installed. Walls on the cartridge surround the shutter during normal use to form a protective light baffle. The laser printhead is fixed within the shroud so that separation requires a necessary electrical cable to be disconnected.

    摘要翻译： 当激光打印机（3）的盖（8）关闭时，没有可替换的盒（15）或护罩组件（9）将激活电和机械互锁。 如果组件被省略，则护罩组件上的可移动开关致动器（16）将不存在，并且如果该盒不存在则不会找到导向斜面，从而确保光源的电力保持关闭。 快门（13）还阻挡正常的光路并且被盒（14）上的销（14）移动，因此除非安装盒，否则挡光。 正常使用时，盒式录像带上的墙壁围绕着快门，形成一个保护性的挡光板。 激光打印头固定在护罩内，使分离需要断开必要的电缆。

    摘要： A developer apparatus (29) for use in an electrostat­ic reproduction apparatus includes a large reservoir of toner (34, 44). The toner is located in a supply chamber (39) and is metered to a developer roller chamber (35) from which it is carried by a developer roller (31) past a doctor blade (36) to a photoconductor drum (19) for image development. A toner metering roller (41) rotates with the developer roller (31) to provide a continuous supply of toner from the supply chamber (39) to the developer chamber (35). Once an equilibrium level (65) is reached, the toner metering roller (41) acts to remove toner (34) from the developer chamber (35) to the supply chamber (39) to insure proper operation of the developer roller (31).

    摘要： An electrophotographic printer having a base and a top, the top being pivotable about an axis (23) between a closed position and an open position. The printer re­ceives a supply cartridge (14) on a shelf (22) which is pivotable about the same axis (23) as the top of the printer. A counterbalance spring (34) helps to support the shelf (22) and the cartridge (14) below the top of the printer and above the printer base when the top of the printer is in its open position. When the top of the printer is closed, the cartridge (14) is urged into a position adjacent the printer base and locked into an operative position.
