摘要： This invention is intended to control the amount of power to be supplied to a fusing heater below a maximum applicable current value. The engine controller supplies electricity to both of two heating bodies at the same fixed duty D1. At a phase angle α1 corresponding to the fixed duty D1, pulse signals ON1 and ON2 are issued in response to a ZEROX signal as a trigger. A current value I1 is detected based on a HCRRT signal from the current detection circuit. The engine controller calculates an upper limit of applicable power duty Dlimit based on the detected current value I1, the fixed duty D1 and the preset applicable current value Ilimit. Then, a PI temperature control is performed at a duty below the upper limit duty Dlimit.

摘要： A period of a first edge, a voltage change in a first direction of a first pulse signal fed from a zero-crossing detecting circuit, is detected. A second edge, a voltage change in a second direction opposite to the first direction, is generated when a time period equal to half the period of the first edge has elapsed from the next first edge. In response to a second pulse signal generated from the first and second edges, phase control of power to be supplied to heating elements is performed by using triacs. In this manner, during power control using a signal from the zero-crossing detecting circuit as a trigger signal, is achieved stable power control which enables tracking even though the power supply frequency fluctuates, and which is impervious to the effect of the positive or negative polarity of an input power supply.

摘要： In an image forming apparatus having a toner container, the remaining amount of toner is detected by measuring a capacitance caused by a toner detector member in the toner container. It is determined whether the measured capacitance falls within a predetermined range. If it is determined that the measured capacitance falls not within the predetermined range, the measured capacitance is not used in the detection of the remaining amount of toner. The present invention thus provides an image forming apparatus reliable in the detection of toner, and a method of controlling the apparatus.

摘要： At step S301, since none of conveyance sensors 114, 116 and 121 detect residual paper, a CPU 203 notifies a CPU 201 that it is in a residual paper check start instruction waiting mode. At step S302, since a conveying path sensor 111 in an optional paper feed unit 101 does not detect residual paper, the CPU 202 notifies the CPU 201 that it is in a residual paper check start instruction waiting mode. At step S303, since an inlet sensor 122 of an optional paper output unit 103 does not detect residual paper, the CPU 204 notifies the CPU 201 that it is in a residual paper check start instruction waiting mode. After confirming that all the units are in the waiting mode, the CPU 201 issues a residual paper check start instruction to all the units simultaneously to improve usability by reducing initializing time.
摘要翻译： 在步骤S301，由于传送传感器114,116和121都没有检测到残留的纸张，所以CPU 203通知CPU201它处于残留纸张检查开始指令等待模式。 在步骤S302中，由于在可选的供纸单元101中的传送路径传感器111不检测到残留的纸张，所以CPU 202通知CPU 201它处于残留纸张检查开始指示等待模式。 在步骤303C中，由于可选纸张输出单元103的入口传感器122没有检测到残留的纸张，CPU 204通知CPU 201它处于残留纸张检查开始指令等待模式。 在确认所有单元处于等待模式之后，CPU 201通过减少初始化时间同时向所有单元发出残留纸张检查开始指令以提高可用性。
