摘要： Image transfer quality in an electrophotographic image forming device is improved by preconditioning a media sheet prior to transferring a toner image thereto at an image transfer station. The media sheet is preconditioned by applying a static charge to it. In a color DTM type device, the charge reduces the transfer voltages required at downstream image transfer stations to account for charge accumulated on the media sheet as a result of the image transfer process at upstream image transfer stations. The charge may be applied to the media sheet at a media sheet preconditioning element positioned upstream of an image transfer station. Alternatively, an initial charge may be applied to the media sheet at an image transfer station, without transferring a toner image to the sheet, and returning the sheet via a duplex path to positioned upstream of an image transfer station prior to an image transfer operation.
摘要翻译：通过在图像转印站转印调色剂图像之前对介质片材进行预处理来改善电子照相成像装置中的图像转印质量。介质片通过对其施加静电荷而被预处理。在彩色DTM型设备中，由于上游图像传送站的图像传送处理，电荷降低了下游图像传送站所需的传送电压，以解决在介质片上累积的电荷。电荷可以在位于图像转印站上游的介质片预处理元件上施加到介质片。或者，可以在图像转印站处将初始电荷施加到介质片，而不将调色剂图像转印到片材，并且在图像转印操作之前将片材经由双工路径返回到图像转印站的上游。

摘要： A biasing mechanism in an image forming apparatus exerts a variable force on a removable cartridge unit to generate a nip force between a roller in the cartridge unit and another roller. A pivot member is fixed to the apparatus housing. An arm is pivotally mounted in the housing about the pivot member, with the arm in contact with a protrusion on the cartridge unit. A force generating member is mounted in the housing and contacts the arm so as to urge the arm to pivot about the pivot member and press against the cartridge unit. The resulting force exerted on the cartridge unit by the arm varies according to the point of contact between the cartridge unit and the arm. In some embodiments, the arm and the cartridge unit protrusion are electrically conductive, and an electrical contact is established as the arm is pressed against the protrusion.

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： 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： The present application is directed to methods and devices for moving a cartridge between engaged and disengaged positions in an image forming device. The image forming device may include a bias control arm movable between first and second positions. When the bias control arm is in one of the first and second positions, a biasing force on the cartridge is reduced and the cartridge moves to the disengaged position. When the bias control arm is in the other of the first and second positions, a biasing force on the cartridge is increased and the cartridge is moved to the engaged position. In one embodiment, the bias control arm moves in a first direction, and the cartridge moves in a second direction different than the first direction.

摘要： An Oldham coupler assembly capable of transferring rotary power between two shafts in a developer unit of an image forming apparatus that includes an input plate and an output plate made of metal and a star plate made in plastic mechanically coupled and positioned in between the input plate and the output plate. A spline component made of metal is rigidly and integrally attached to the input plate, the spline component including a tubular spline portion that includes a plurality of wear strips made of plastic, the output plate having a plastic material coated along a portion of an outside diameter of the output plate. The input and output plates further include a plurality of openings to receive a plurality of wheels and pins. This structure allows a sufficiently stiff drive system to substantially eliminate fine line jitter by raising the natural frequency of the drive system.
