摘要： The present application is directed to methods and devices for determining a media level in an input area within an image forming device. In one embodiment, a support section configured to hold a stack of media sheets is positioned in the image forming device. A pick mechanism is positioned to contact a top-most media sheet of the stack of media sheets in the support section. The pick mechanism may include a pick motor and a pick roller. A sensor roller may be positioned separate from the pick roller and in contact with the top-most media sheet. A controller may determine the media level based on a movement of the sensor roller after the top-most media sheet has moved to a predetermined location.

摘要： A bearing for an imaging apparatus includes a first bearing flank including a first bearing surface having a shape in cross-section defined by a first arc having a first radius extending from a first surface axis. The bearing further includes a second bearing flank including a second bearing surface having a shape in cross-section defined by a second arc having a second radius extending from a second surface axis. The first bearing flank and the second bearing flank are structured and adapted such that the first bearing surface and the second bearing surface together in cross-section form a concave shape, and such that the first bearing surface and the second bearing surface are non-concentric. Alternatively, the first and second bearing flanks can be replaced by roller bearings.

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）并保持感光鼓（43）的整体组件。每个侧壁具有从料斗（61）侧松散地接收销（37a，37b）的U形壳体（35,247）。料斗是保持调色剂加料辊（45）和显影辊（43）的整体组件的一部分。来自料斗侧面的第二销（131a，131b）携带弹簧，弹簧将两个组件拉在一起，将显影辊压靠在感光体上。料斗还在每一侧都有平面的凸缘（161a，133a），用于在打印机中的辊上运动。这进一步允许盒具有中心定位元件（29a，29b），用于插入的翼状引导件（9a，9b），用于打开下挡板（7）的连杆（13a，13b）和感光体轴（ 47）用于积极地定位在该轴上。

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, 9bb) to better guide the cartridge. The guides are a part of a unitarily molded cover assembly which includes the side walls (33, 241, 245).

摘要： A toner cartridge (1) contains a photoconductive drum (43) having a central shaft (47). The shaft extends outward from the sides of the cartridge so that it can be lowered on a V-shaped locator (301) in the printer. An assembly of a hopper (61), toner adder roller (45) and developer roller (43) is attached to an assembly carrying the photoconductive drum through springs (132a, 132b). The hopper assembly has center locating surfaces (29a, 29b) to receive a downward pressing member from the printer and flat ledges (161a, 133a) to contact rollers in the printer, which permits adjustment of the contact between the drum and the developer roller while positively locating the drum. The cover assembly also has flat locating surfaces (449, 451) near the hopper to rest on the printer frame.

摘要： The door (3) of a laser printer (1) is pivoted to the frame (1c) of the printer by a pin (21) of hinge (19). When the door is shut, link (33) is rotatably connected to the hinge at a location above the pin. Link 33 has an elongated slot (33a) at its end opposite the hinge in which a pin (51) does not encounter the edge of the slot when the door is closed. Spring (31) therefore rotates U shaped link 11 around its pivot point (15) to the frame to bring charge roller (9) into contact with photoconductor drum (5). When the door is manually opened, spring 31 provides an upward force, link 33 is moved forward where the slot engages pin 51, which pivots both link 13 and door 3 upward. Force of the charge roller against the drum is by the spring as the only active element, thereby providing a controlled force.
摘要翻译：激光打印机（1）的门（3）通过铰链（19）的销（21）枢转到打印机的框架（1c）。当门关闭时，连杆（33）可旋转地连接到销钉上方的铰链处。连杆33在其与铰链相对的端部处具有细长的槽（33a），当门关闭时，销（51）不会遇到槽的边缘。因此，弹簧（31）将U形连杆11围绕其枢转点（15）旋转到框架，以使充电辊（9）与感光鼓（5）接触。当门被手动打开时，弹簧31提供向上的力，连杆33向前移动，其中狭槽接合销51，其将连杆13和门3向上枢转。充电辊抵靠鼓的力通过弹簧作为唯一的有源元件，从而提供受控的力。

摘要： A method and device for controlling toner transfer during the formation of a toner image within an image forming device is described herein. One exemplary image forming device includes a toner reservoir that stores toner of a first color, a developer member that receives toner from the toner reservoir, a photoconductive member proximate the developer member that receives toner from the developer member, and a driver. While rotating the photoconductive member, the driver selectively rotates the developer member based on a color content of the image. For example, the driver does not rotate the developer member while rotating the photoconductive member when the toner image being formed lacks the first color. Alternatively, the driver lows the rotational speed of the developer member while rotating the photoconductive member when the toner image being formed lacks the first color.
