摘要： Apparatus and method for monitoring print quality produced by a digital printing mechanism in real-time. Print quality is measured by: generating a background reflectance signal representative of the reflectance of a substrate; scanning the image to generate a post-print reflectance signal; comparing the reflectance signal with the post-print reflectance signal; and, if the post-print reflectance signal is greater than a predetermined fraction of said reflectance signal, generating an output signal indicative of poor quality. In one embodiment of the invention, the output signal is also generated if the post-print reflectance signal is less than a predetermined minimum value.

摘要： Predetermined print control signals are provided to a digital printing mechanism that responds to the print control signals to print an image on a substrate. A reference signal is derived from said print control signals. The image is scanned to generate a post-print signal. The reference signal is compared with said post-print signal. If the reference signal and the post-print signal do not compare within predetermined standards, an output signal indicative of poor print quality is generated. The print mechanism can be incorporated into a postage metering system and the image can be a postal indicia. The postage meter is responsive to a signal generated as a function of the output signal to inhibit further printing of postal indicia. Prior to printing the image, a substrate upon which the image is to be printed is scanned to generate a reflectance signal, the reflectance signal being used to correct the post-print signal. The post-print signal can represent integration of reflectance over segments of the image, or can represent summation of scanned pixels over segments of the image.

摘要翻译：用于实时监控由数字打印机构产生的打印质量的装置和方法。打印质量通过以下方式测量：产生表示基板的反射率的背景反射信号; 扫描图像以产生后打印反射信号; 将反射信号与后打印反射信号进行比较; 并且如果后打印反射信号大于所述反射信号的预定分数，则产生指示质量差的输出信号。在本发明的一个实施例中，如果后打印反射信号小于预定最小值，则也产生输出信号。

摘要： A sensor is paired with an emitter, such as in a postage metering machine, and the sensor is calibrated for ambient light conditions. Ambient light is measured with a sensor while the emitter is unpowered. If the measured ambient light is less than a current trip level (voltage level at the sensor), then a current level of light is measured with the sensor while the emitter is powered. If the measured current level of light exceeds the current trip level, then the signal output from the sensor indicates that an object such as an envelope awaiting postage to be printed thereon is present at the sensor. The current trip level may be determined by measuring light at the sensor when the emitter is on and adding some voltage margin to it, but if the sensor is blocked during this calibration a default threshold is used as the current trip level.
