    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: A mailing machine comprising a printer module, a transport device and a controller in operative communication with the transport device and the printer module. The printer module including an array of ink jet print elements for printing on an envelope and a repositioning device in operative engagement with the array of ink jet print elements for moving the array of ink jet print elements between a maintenance position and a print position. The transport device including suitable structure for feeding the envelope in a path of travel so that the envelope passes in opposed relationship to the array of ink jet print elements when the array of ink jet print elements are in the print position. The controller keeps an indicator of an amount of time elapsed between printing successive envelopes. If the indicator reaches a predetermined threshold, then the controller causes the array of ink jet print elements to perform a maintenance operation by firing the array of ink jet print elements in the absence of the envelope while the printer module is in the print position.
