original sensor: original detection operation
The machine looks for a change in the output level of individual sensors for a period of 2 sec after the
ADF open/closed sensor (ADF) has identified the current state as being "closed." The absence of a
change in the level causes the machine to assume the presence of an original at the point in question.
The machine uses the combination of changes in the levels of 5 points to identify the size of the original
in question.
