    • A postage meter is disclosed which determines whether postage was printed while power to the meter was off, and if so accounts for such postage printing. The postage meter also determines whether such printing resulted from tampering, and if so records each instance of such tampering. When the number of instances exceeds a predetermined number, the meter prevents further normal operation thereof. The postage meter is provided structure and programming to accomplish the foregoing because it does not include a print device locking mechanism that locks the print devices when power to the meter is switched off. The postage meter determines print cycles of the postage meter occurring when power to the meter is switched off and whether the print devices were moved to a different postage value setting when the meter was off, and if so, the new setting of the print devices. From that, the postage meter determines whether postage was printed while power to the meter was switched off, and if so, accounts for the postage printed.
    • 公开了一种邮资计费器,其确定在电表的电量关闭时邮费是否打印,如果是这样的话,则邮费打印。 邮费计还确定这种打印是否由篡改导致,如果是这样,记录每一个这种篡改的实例。 当实例数超过预定数量时,仪表防止其进一步正常操作。 为了实现上述目的,提供了邮资计费器的结构和编程,因为它不包括当关闭仪表的电力时锁定打印装置的打印装置锁定机构。 当电表关闭电源时,邮资计费器确定邮资计费器的打印周期,以及当仪表关闭时打印设备是否移动到不同的邮资值设置,如果是,则打印设备的新设置。 从那里,邮费计算机确定在电表断电时是否打印邮费,如果是,则打印邮费。
