*1 Time control, not pulse control, is used for only this period because the pulse count for the
period changes greatly due to the high and low paper transport speeds.
*2 "A pulses" depends on which bin the paper is going to. For the first bin, this period is 202
pulses.
*3. "B pulses" is the length of time that the inlet sensor is ON. This period is uncertain because
it depends both on the length of the paper and the amount of paper slippage.
