摘要： A laser printer having a rotating mirror (116) and a heat fuser (220) is operated with a sequence of standby conditions. At the end of a print job mirror (116) is continued to be rotated at printing speed while the temperature of fuser (220) is reduced somewhat. This is maintained for a short time, after which the speed of rotation of mirror (116) is reduced significantly and the fuser (220) temperature is reduced significantly. This is maintained for a time, after which the mirror is no longer rotated (or, if practical, is rotated very slowly) and the fuser temperature is further reduced. At any time when a subsequent print job is received, the mirror and fuser are brought to printing state and the period of times are next started from a beginning state.

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： The number of pages of a print job received at printer (10) is determined (256). If the number of pages is low, printing is conducted at intermediate speed (262). If the number of pages is higher, printing is conducted at high speed (254). If the number of pages is not known, a default is selected (260). The default often will be to print at intermediate speed because most jobs are short. If high speed printing is in progress when a job is received, the next job is printed at high speed (254). Alternatively, a predetermined number of the first pages of a job may be printed at intermediate speed.

摘要： A printer has a media feed path (12) for feeding sheets of media (14), with the path having a side reference edge (52) for aligning the media. A media transport mechanism feeds the sheets of media at a standard speed and at a reduced speed. A narrow media detector (38) generates a narrow media signal when sheets of narrow media are fed through the media feed path. A controller (68) adjusts the media transport mechanism to feed the narrow media aligned with the reference edge at the reduced speed. A method of printing sheets of narrow media in a printer comprises the steps of aligning the narrow media with a reference edge in a media feed path of the printer, sensing when the narrow media are present in the media feed path, and feeding the narrow media through the media feed path at the reduced sheet feeding speed and, particularly with a belt fuser, with increased inter-sheet gap.

摘要： A system, method and article for adjusting the time interval between feeding of successive sheets of media in a printer or copier. The method comprises initiating a first pick signal for a sheet of the media and identifying a feed time for the sheet of media, and identifying an expected feed time for said media. The system compares feed times to an expected feed time and adjusts according to such comparison to substantially correct for slippage or other problems feeding diverse media.

摘要： Printer has a standby state in which the motor driving the laser scanning mirror is turned off immediately after a print job when another page is not ready. To increase operating speed, a signal to the printer starts a timer (Ready timer). When a page is printed, the timer is started and only when it reaches zero is the motor turned off. When data of a page is received by the printer and the Ready timer is non-zero, a sheet is immediately picked for printing.

摘要： A printing device (10) such as a laser printer includes a fuser assembly (200) with a fuser wiper (210) that can be removed and replaced by a user during normal maintenance to extend the useful life of the fuser assembly (200). Indicators (b0, b1) stored in a memory device (144) can be read by a print engine (36) of a printer (10) either when a print cartridge (100) is first inserted into the printer (10) or at specified times thereafter. Depending on the contents of the memory device (144), the print engine (36) may send a notification message to the printer's raster image processor (150) to cause a message to be displayed on the printer's operational/display panel (254) that informs a user the fuser wiper (210) should be replaced.

摘要： Before warm-up of a printer, sheets are initially fed for printing based on a normal assumed lock time for rotation of polygonal mirror (116) of a laser printhead (100). After an initial printing when in a mode in which the printer is warmed, such as a standby mode, sheets are fed for printing based on a lock time shorter than the normal lock time. When a lock time failure is observed when using the shorter lock time, use of the longer lock time is resumed. Time to begin printing is improved by the use of the shorter lock time.

摘要： Control (P) of imaging device (1) senses the period of time sensor (17) senses media (5) at input feed roller (16a). When a too-long-over-sensor condition is sensed, drive of input feed roller (16a) is terminated by operation of clutch (C). A feed roller (19a) farther in the media path continue to operate. One sheet of media (5) is fed while a dual fed sheet is held in the nip of feed roller (16a) and idle roller (16b). Subsequently, feed roller (16a) is again driven to feed the dual fed sheet for normal imaging.
