2.7.6.4 ADC Solenoid Operation

Every 1000 counts (nominal) the ADC Solenoid operates twice (nominal) at a
cycle of 0.5sec ON AND 0.5sec OFF. This causes the light emission/reception
parts of the ADC Sensor to be cleaned by the cleaning lever.
NOTE: Count is a cumulative total that is incremented by 1 when the
length of paper in the paper transport direction is 219mm (LETTER
[LEF]) or less, and incremented by 2 when the size of the paper
exceeds 219mm (LETTER [LEF]).
