ABSTRACT:
A mailing machine comprising, structure for feeding a sheet in a path of travel, structure for printing indicia on the sheet, structure for controlling the sheet feeding and printing structure, the controlling structure including a microprocessor, the controlling structure including structure for sensing the sheet in the path of travel, the sensing structure including a first sensor for sequentially sensing the leading and trailing edges of the sheet and providing corresponding sequential first signals to the microprocessor, the sensing structure including a second sensor downstream from the first sensor for sensing the leading edge of the sheet and providing a corresponding second sensing signal to the microprocessor, and the microprocessor programmed for causing the sheet feeding structure to feed the sheet, commencing a count of a first time interval when the trailing edge of the sheet is sensed by the first sensor, determining whether the first time interval count is less than a predetermined second time interval when the leading edge of the sheet is sensed by the second sensor, and terminating sheet feeding if the first time interval count is not less than the predetermined second time interval.
