    • In an electrophotographic printing apparatus, a fixing device heat-roller control system configured for specially controlling the heat roller fixing temperature during consecutive dual-sided copying of a large number of sheets. The electrophotographic printing apparatus in particular is adapted for stack-less conveyance from the fixing unit of sheets onto one side of which the copy toner image has been fixed in dual-sided copying, switching the sheets back to image reproduction unit. The fixing unit has a heat roller incorporating an internal heater and a press roller in pressing contact with the heat roller. The fixing device heat-roller control system includes a sensor associated with the heat roller for detecting its superficial temperature, a switching element for supplying/cutting off voltage to the internal heater, and a temperature control unit connected to the sensor and the switching element. Based on detection output from the sensor, the temperature control unit controls the switching element to maintain target heating temperatures in the heat roller, such that in consecutive dual-sided printing a number of sheets, for every multiple of a predetermined printing sheet count, the target heating temperature in the heat roller lowers in predetermined stages to a predetermined temperature, below an initial target heating temperature for toner-image fixing sheets in single-sided printing.
    • 在电子照相打印设备中,一种定影装置加热辊控制系统,其被配置为在连续双面复印大量纸张时专门控制热辊定影温度。 特别地,电子照相打印设备适用于从纸张的固定单元向双面复印中固定有复印调色剂图像的一侧的无堆叠输送,将纸张切换回图像再现单元。 定影单元具有包括内部加热器的加热辊和与加热辊压接的加压辊。 定影装置的热辊控制系统包括与用于检测其表面温度的热辊相关联的传感器,用于向内部加热器供电/切断电压的开关元件,以及连接到传感器和开关元件的温度控制单元。 基于来自传感器的检测输出,温度控制单元控制开关元件以保持加热辊中的目标加热温度,使得在连续的双面打印多个片材中,对于预定打印纸张数的每一倍, 加热辊中的目标加热温度在预定阶段下降到预定温度,低于用于单面打印中的调色剂图像定影片材的初始目标加热温度。

    • A bit synchronizing circuit is arranged by a bit synchronization counter constructed of an up/down counter or an adding/subtracting counter; an edge detector for detecting an edge of an input NRZ signal to output an edge detection pulse; two sets of edge number counters for counting total numbers of edge detection pulses outputted from the edge detector during a 1 cycle of the counting operation by the bit synchronization counter; and two sets of registers for fetching the count value of the bit synchronization counter at the time instant every time the edge detector outputs the edge detection pulse, and also for storing an accumulation value of the count values fetched during the 1 cycle of the counting operation by the bit synchronization counter. Both the two edge number counters and the two registers are operated with shifts of a half cycle, respectively. This bit synchronization circuit is further arranged by a judging circuit for judging a synchronization shift amount between the input NRZ signal and the counting operation by the bit synchronization counter based on the count values of the two edge number counters and the accumulate values stored in the two registers, and for outputting a correction signal corresponding to the judgment result to the bit synchronization counter.
