    • In a discharge lamp lighting device that, at a time of starting a discharge lamp La, alternately repeats periods HF1 and HF2 while high frequency voltages are being outputted, in which a resonant circuit performs resonant operations, and periods FB1 and FB2 while square wave voltages are being outputted, and at a time of lighting the discharge lamp La, applies a low-frequency square wave voltage to the discharge lamp La through a starting circuit 4, there are provided: a starting detection circuit 5 that detects the starting of the discharge lamp La during the periods FB1 and FB2 while the square wave voltages are being outputted; and a control circuit 3C that stops the high frequency voltage or lowers a frequency of the high frequency voltage in the case where the starting of the discharge lamp La is detected. In the case where the starting of the discharge lamp La has been detected at least once, the control circuit 3C increases the number of repetitions of a period while the high frequency voltage and the square wave voltage are being outputted alternately. In such a way, in the discharge lamp lighting device that alternately generates the high frequency voltage and the square wave voltage at the time of the starting, sure startability is ensured.
    • 在放电灯点亮装置中,在放电灯La起动时,在输出谐振电路进行谐振动作的高频电压的同时交替重复周期HF1,HF2,在方波电压的期间,周期FB1,FB2 正在输出,并且在点亮放电灯La时,通过起动电路4向放电灯La施加低频方波电压,其特征在于,设有检测放电开始的起动检测电路5 在输出方波电压的期间FB1和FB2中的灯La; 以及在检测到放电灯La的启动的情况下停止高频电压或降低高频电压的频率的控制电路3C。 在已经检测到放电灯La的起动至少一次的情况下,控制电路3C在交替地输出高频电压和方波电压的同时增加周期的重复次数。 以这种方式,在起动时交替产生高频电压和方波电压的放电灯点亮装置中,确保可靠的启动性。

    • A host computer does not instruct to initiate calibration immediately when calibration is requested by a printer. The host computer instructs to initiate calibration at time which is designated by an operator. As for the execution time of calibration to be designated, time right after calibration is requested, and time when a printing job is completed are included. Further, when automatic determination for determining execution time of calibration is designated, the execution time is determined on the basis of state of a printing job to be executed, or state of a printing job in progress. As for the state of a printing job, there are the number of remaining pages of the printing job, color printing or monochromatic printing, whether image data is included or not, for example. Accordingly, depending upon the state of the printing job, an optimized execution time of calibration is determined.
    • 当打印机要求校准时,主机不会立即指示启动校准。 主机指示在由操作员指定的时间开始校准。 对于要指定的校准的执行时间,请求校准后的时间,并且包括打印作业完成的时间。 此外,当指定用于确定校准执行时间的自动确定时,基于要执行的打印作业的状态或正在进行的打印作业的状态来确定执行时间。 对于打印作业的状态,例如,是否包括打印作业的剩余页数,彩色打印或单色打印,是否包括图像数据。 因此,根据打印作业的状态,确定优化的校准执行时间。
