<Double Feed Control>
•
Even if the Paper Take-Up Roll takes up two sheets of paper at one time,
the double feed control uses the second sheet of paper for the next copy
cycle without causing a paper misfeed. It eliminates a paper misfeed that
would otherwise result when two sheets of paper are taken up at once.
•
If the second sheet of paper is stationary blocking the Paper Take-Up
Sensor (PC6/7/8) when the trailing edge of the first sheet of paper moves
past the Vertical Transport Sensor (PC10/11/12), the copier determines
that it is a double feed condition and provides double feed control.
•
If, however, the second sheet of paper has reached the Vertical Transport
Roller, the double feed control is not provided since the paper is fed further
into the copier by the Vertical Transport Roller. This could result in a paper
misfeed or the second sheet of paper being fed through the copier with the
first one.
•
If double feed control is provided, it results in the paper take-up interval
timing becoming longer. That means longer intervals between two
successive paper take-up motions, resulting in a decreased cpm
(productivity).
