functions are located on the LED/CPU board.<br />
Hardware Functions<br />
Recorder Driver Circuit Board<br />
This circuit takes all control instructions from the LED/CPU board and provides<br />
printhead drive decoding, paper drive motor control logic decoding, printhead “home<br />
switch” position sensing and pulse width modulated oscillator for print head drive.<br />
