摘要： A printhead (19) is adjusted automatically or manually with respect to a platen (12) in accordance with the thickness of a recording medium. When a host data processor sends a control signal to the printer microprocessor to indicate that a recording medium of a different thickness is to be printed, a carrier (18), which has a first portion supporting the printhead (19) and pivotally and slidably mounted on a front guide rail (16), is moved so that a shift arm (34) on the carrier (18) engages a right side plate of the frame. This disconnects a ribbon drive motor gear from a ribbon drive gear and moves the ribbon drive motor gear into engagement with a gear (23) train. Rotation of the gear train rotates a gear, which has a threaded shaft and is rotatably supported by a second portion of the carrier slidably mounted on a rear guide rail, to cause pivoting of the first portion of the carrier about the front guide rail (16) to change the gap of the printhead from the platen. When the gap change is completed, the carrier is moved to the left to its recording medium loading printing position and to disengage the ribbon drive motor gear from the gear train and reengage it with the ribbon drive gear. Then, manual adjustment of the spacing of the printhead from the platen may be accomplished through handle 64 which controls rotation of gear 23 through shaft 61.

摘要： Hopper plug (143) vents out air pressure build-up which would cause toner leaks. One side of the plug has a series of entrance openings (491) which communicate with the inside of the hopper (61). Air, potentially containing some toner particles, passes through those openings and enters a first chamber (507). The first chamber has exit holes (499) which do not face the entrance openings. Air passing through the exit holes of the first chamber enters a second chamber (509). The second chamber has exit holes (495) which are at the opposite end and do not face the entrance openings. Third chamber (511) of this labyrinth faces a mat toner filter (501) which leads to exit holes (503).

摘要： Toner cartridge (1) has a unitary assembly forming the handle (3a, 3b), the cover (25), side walls (33,245) and the cleaner chamber (27) and hold the photoconductor drum (43). Each of the side walls has a U-shaped housing (35,247) which loosely receives a pin (37a, 37b) from the side of the hopper (61). The hopper is part of a unitary assembly holding the toner adder roller (45) and the developer roller (43). Second pins (131a, 131b) from the sides of the hopper carry springs which pull the two assemblies together to press the developer roller against the photoconductor. The hopper also has flat ledges (161a, 133a) on each side for movement on roller in the printer. This further permits the cartridge to have central locating elements (29a, 29b), wing-like guides (9a, 9b) for insertion, links (13a, 13b) to open a lower shutter (7), and unobstructed ends of photoconductor shaft (47) for positively locating on that shaft.
摘要翻译：调色剂盒（1）具有形成手柄（3a，3b），盖（25），侧壁（33,245）和清洁器室（27）并且保持感光鼓（43）的整体组件。每个侧壁具有U形外壳（35,247），其从料斗（61）侧松散地接收销（37a，37b）。料斗是固定调色剂添加辊（45）和显影辊（43）的整体组件的一部分。离开料斗侧面的第二销（131a，131b）带有弹簧，该弹簧将两个组件拉在一起以将显影辊压靠在光电导体上。料斗还在每一侧上具有平坦的凸缘（161a，133a），用于在印刷机上的辊子上移动。这进一步允许盒具有用于插入的中央定位元件（29a，29b），翼状导向件（9a，9b），打开下部活门（7）的连杆（13a，13b）以及光电导体轴的无障碍端部 47）可靠地定位在该轴上。

摘要： A toner cartridge (1) comprises a single molded element, molded of polystyrene, which is heat sensitive. The molded element forms front handles (3a, 3b) and a cleaner chamber (27) mounts a photoconductor drum (49). A toner hopper (61) is located generally under the handles. A developer roller (43) receives toner from the hopper and applies it to the photoconductor drum. A lower shutter (7) of polycarbonate, which is heat resistant, is mounted on actuating links (13a, 13b). When the cartridge is installed in the printer the actuating links are moved to rotate the shutter to a position covering the lower surface of the cleaner chamber, where it serves as an effective heat shield protecting the cleaner from fixing heat of the printer.
摘要翻译：调色剂盒（1）包括热敏感的由聚苯乙烯模制的单个模制元件。模制元件形成前手柄（3a，3b），并且清洁器腔室（27）安装光导鼓（49）。调色剂料斗（61）通常位于把手下方。显影辊（43）从料斗接收调色剂并将其施加到感光鼓上。一个耐热的聚碳酸酯下挡板（7）安装在驱动连杆（13a，13b）上。当墨盒安装在打印机中时，致动连杆被移动以将遮门旋转到覆盖清洁室的下表面的位置，在那里它用作有效隔热屏，以保护清洁器免于固定打印机的热量。

摘要： A toner cartridge (1) has wing-like guides (9a, 9b) on opposite sides, the guides being curved to follow a curved guide track in a printer in which the cartridge is installed. The cartridge may be readily grasped by handles (3a, 3b) and inserted in the guide tracks of the printer near the top and front and then readily directed down and into the rear area of the printer.
The guides are thin at their initial location of entry into the printer for easy insertion and increase to larger thickness regions (9aa) to better guide the cartridge. The guides are a part of a unitarily molded cover assembly which includes the side walls (33, 241, 245).
