摘要： The write lines of a color laser printer are maintained substantially equal throughout the printer's operation by an electronic control arrangement. At the factory, the write lines on all photoconductors of the color laser printer are calibrated to be substantially equal, and the ratio of each write line to a measuring line for each photoconductor is ascertained. During operation of the printer, the length of each of the measuring lines is periodically determined through counting the number of PELslice clock timing pulses produced from a PELslice clock operating at a fixed frequency determined during factory calibration. The length of the write line is determined by the product of the length of the measuring line and the factory calibrated ratio of the length of the write line to the length of the measuring line. After each periodic determination, PELslice clock timing pulses are selectively inserted into or removed from the PELslice clock timing pulses for all of the write lines but the write line, which is closest to the desired length, to increase or decrease their lengths to be substantially equal to the write line, which is closest to the desired length. The time for insertion or removal of each of the PEL slices into the train of PELslice clock timing pulses produced by the PELslice clock is determined with each preferably inserted at a non-active portion of a PEL. Each insertion or removal of a PEL slice also may be offset from its determined position.
摘要翻译：彩色激光打印机的写入线通过电子控制装置在整个打印机的操作中保持基本相等。在出厂时，彩色激光打印机的所有感光体上的写入线被校准为基本相等，并确定每个写入线与每个感光体的测量线的比例。在打印机的操作期间，通过对在工厂校准期间确定的固定频率下操作的PELslice时钟产生的PELslice时钟定时脉冲的数量进行计数来周期性地确定每个测量线的长度。写入线的长度由测量线的长度与写入线的长度与测量线的长度的出厂校准比的乘积确定。在每个周期性确定之后，PELslice时钟定时脉冲被选择性地插入到所有写入线的PELslice时钟定时脉冲中或从其中去除，但最接近所需长度的写入线将其长度增加或减小到基本相等到最接近所需长度的写入线。将每个PEL切片插入或移除到由PELslice时钟产生的PELslice时钟定时脉冲串中的时间被确定，每个优选地插入在PEL的非有效部分。 PEL切片的每个插入或移除也可以偏离其确定的位置。

摘要： A cartridge (30) for an electrophotographic machine is disclosed having a sump (33) for carrying an agitator (34) rotatably mounted in the sump (33) for engagement with toner (35). An encoded device (31) is coupled to a first end of the agitator (34). A torque sensitive coupling is connected to a second end of the agitator (34) which is connectable to a drive mechanism of the machine. The encoded device (31) includes coding means representing cartridge characteristic information. The coding means may be a plurality of cam surfaces or a plurality of reflective surfaces. Alternatively, the coding means may be a plurality of openings in the encoded plate which are detected by the use of a magnetic field sensor and a magnet.

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).
