摘要： A method and apparatus for providing transfer quality optimization in printers is disclosed. A transfer belt subassembly includes a transfer belt and a storage device. The transfer belt also includes a home position indicator. The transfer belt subassembly is measured and characterized relative to the home position indicator before being installed in a printer. The measurement and calibration data for the transfer belt is then stored in the storage device that is part of the transfer belt subassembly. When the transfer belt subassembly is inserted into a printer, a controller within the printer is placed in communication with the storage device. A sensor is used to determine the home position of the transfer belt from the indicator, and a resulting signal indicating when the belt is at the home position is provided to the controller. The controller utilizes the measurement and calibration data from the storage device to provide correction with respect to each color station of the color printer, taking into account and compensating for variations in the transfer belt subassembly. In such a manner, the measurement and calibration data is predetermined before the transfer belt subassembly is inserted into the printer, thereby simplifying the printer composition. By use of the calibration and measurement data, precise alignment of the color planes with respect to one another is achieved, and the proper electrical transfer setting suited to that belt is obtained for improved transfer quality.

摘要： An improved EP printer will automatically compensate for printer output darkness shift over the usage life of one or more components of the print engine. In many EP print engines, the printer output darkness without correction will gradually change as the components are used, and typically, the darkness will increase to an extent that is perceptible. The printer output darkness can be controlled using a EP operating point that changes certain operating parameters, such as the laser diode current, the duty cycle of the video data signals driving the laser diode, and other voltage parameters including the charge roller voltage, or the developer bias voltage. It is desirable to make adjustments over the usage life of these components, so as to maintain the initial printer output darkness throughout the life of the major system components. The adjustments can occur at periodic intervals based upon a metric that includes one or more of the following parameters: number of pels produced, number of pages printed, number of cycles of one or more components of the print engine, and/or the consumption of toner in grams. The adjustment information can be provided as look-up tables, or in the form of transfer functions. If look-up tables are used, the adjustment control algorithm could be one that interpolates between periodically-adjusted usage values stored in the look-up tables. Since many EP process cartridges tend to print darker rather than lighter over the life usage of that process cartridge, the present invention will accomplish two important goals by utilizing the methodology described above; not only will the printer output darkness be maintained at a substantially constant value, but the actual number of pels printed and pages printed will be increased by use of the same quantity of toner stored within the replaceable process cartridge.

摘要翻译： 改进的EP打印机将自动补偿在打印引擎的一个或多个部件的使用寿命内的打印机输出暗度偏移。 在许多EP打印引擎中，打印机输出黑暗而不进行校正将随着使用组件而逐渐改变，并且通常黑暗将增加到可察觉的程度。 可以使用EP工作点来控制打印机输出暗度，该EP工作点改变某些操作参数，例如激光二极管电流，驱动激光二极管的视频数据信号的占空比，以及包括充电辊电压的其它电压参数，或 显影剂偏压。 期望调整这些部件的使用寿命，以便在主要系统部件的整个使用寿命期间保持初始打印机输出暗度。 调整可以基于包括以下参数中的一个或多个的度量的周期性间隔发生：所生成的像素数，打印页数，打印引擎的一个或多个组件的循环次数和/或消耗 墨粉以克计。 调整信息可以作为查询表提供，也可以以传递函数的形式提供。 如果使用查找表，则调整控制算法可以是在存储在查找表中的周期性调整的使用值之间进行内插的算法。 由于许多EP处理盒倾向于在该处理盒的使用寿命期内打印更暗而不是较轻，所以本发明将通过利用上述方法实现两个重要目标; 不仅打印机的输出暗度维持在基本恒定的值，而且通过使用存储在可更换的处理盒中的相同数量的调色剂，可以增加印刷的页数和打印页数的实际数量。

摘要： An image-forming device includes a media path extending through the image-forming device, and at least one image transfer nip positioned along the media path. An electrode is positioned subsequent to the nip with respect to the media path and is coupled to a voltage source. An electric field produced by the electrode and voltage source limits the degree of post-nip toner scattering by applying an electrostatic force to toner particles on media sheets passing along the media path. The image-forming device further includes a processor for monitoring a plurality of ambient conditions, for adjusting the voltage applied to the electrode, and optionally, for repositioning the electrode with respect to the media path.

摘要： A method of aligning print images of an electrophotographic machine on a print medium includes reflecting a first laser beam off of a first rotating reflector to thereby scan the first laser beam across a first photoconductive drum to produce a first scan line in a scan direction. The rotation of the first reflector is cyclically repeated to thereby produce a plurality of substantially parallel first scan lines on the first photoconductive drum. A respective line of first toner is applied to each of the first scan lines. A second laser beam is reflected off of a second rotating reflector to thereby scan the second laser beam across a second photoconductive drum to produce a second scan line in the scan direction. The rotation of the second reflector is cyclically repeated to thereby produce a plurality of substantially parallel second scan lines on the second photoconductive drum. A respective line of second toner is applied to each of the second scan lines. A moving toner transfer medium contacts each of the first photoconductive drum and the second photoconductive drum. Each line of first toner is transferred from the first photoconductive drum to the toner transfer medium. Each line of second toner is transferred from the second photoconductive drum to the toner transfer medium such that the lines of second toner are substantially interspersed with the lines of first toner on the toner transfer medium. The lines of first toner and the lines of second toner are transferred from the toner transfer medium to the print medium. A desired phase difference between the rotation of the first reflector and the rotation of the second reflector is determined. The desired phase difference is such that at least one line of first toner is substantially aligned in a process direction with a corresponding line of second toner on the toner transfer medium. The process direction is substantially perpendicular to the scan direction. A speed of the rotation of the first reflector and/or the second reflector is temporarily changed to thereby achieve the desired phase difference therebetween.

摘要： A toner cartridge (1) contains a photoconductive drum (49) having a central shaft (47). Gear (145) turns with the drum and has a stud (602). A coil spring (604) is mounted on the stud to form a spring clutch which is unwound by the rotation of the drum during imaging. Alternatively, a flat frictional surface is pressed against the side wall (600b) of the gear. Both contact areas have a light grease. The drag forces provide accurate, smooth operation during imaging.

摘要： A toner cartridge (1) has a cylindrical toner hopper (61) with a rear wall (61a) defining an output opening well above the lower part of the hopper. A paddle (63) is rotated in the hopper. The exit surface (61aaa) declines downward to form a chamber for the toner adder roller (45) and developer roller (43). This configuration discourages toner from returning to the hopper after it has been electrically charged.To improve movement of toner past the opening an agitator bar (65) extends across the cartridge near the exit surface. The bar is pivoted at both ends and has a portion (65a) which extends into the path of the paddle. As the paddle rotates, it moves the agitator upward until the curved paths of the two members reach separation, at which time the bar drops by gravity. The bar jars toner loose and eliminates jams of toner. The flat surface of the bar, when it has been moved up, partially blocks the exit opening, which desirably limits toner flow.
