摘要： A power-down circuit includes a power-on reset circuit that determines whether the supplied power falls below a prescribed level and, in response, outputs a reset signal for at least a prescribed period of time. A power supply latching circuit is responsive to the power-on reset circuit for switching on a power supply switching circuit to supply power from a power supply when the reset signal is not output. A power-down shutdown circuit, preferably under software control, and a power cutoff circuit, may be coupled to the power supply latching circuit, or alternatively the power-on reset circuit, for shutting down the power supplied from the power supply.

The mailing machine including a controller for controlling the operations of the mailing machine and a printer transport for transporting the digital printer to a cleaning station when the printer is not in use. A sensor is positioned at the cleaning station for sensing the presents of the printer and generating an output to the mailing machine controller in response. The mailing machine power supply includes a main transformer and a plurality of secondary transformer in parallel electrical communication over first and second electrical lines. A single-pole-double-throw switch has its first input and output stage interposed between the first electrical line between the main transformer and one of the second transformers. The second input and output stage of the switch is in electronic communication with the mailing machine controller such that when the switch is open a first voltage level is received by the mailing machine controller and when the switch means is closed a second voltage level is received by the mailing machine controller. The switch provides an electrical by-pass alone the first electrical line around the first input and output stage of the switch when the switch is open unexpectedly by an operator. A by-pass gate responses to the initial opening of the DPST switch to provide a power by-pass until the mailing machine controller is informed that the printer is properly positioned in the cleaning station.

摘要： A method for controlling the speed of a motor for a tape drive in a mailing machine includes providing an optical sensor for signaling the appearance of slots in a slotted wheel connected to the motor shaft. The time intervals between slots are used to make a prediction in respect of expected future time intervals and the motor speed is adjusted in accordance with the predicted value to obtain the desired value. For best results, the data is received at the microprocessor using the "capture" mode of operation in order to avoid excessive errors due to a "busy" processor. The invention enables the small motor of a tape drive to avoid over and undershoot even when operating under highly variable load conditions.
