(5) Aligning sensor OFF to timing sensor OFF
The feed motor stops at the point when the timing sensor turns OFF and the trailing edge of the
original is detected. If exit operation is not carried out simultaneously or has already completed at this
time, the reversal motor starts to rotate in the forward direction simultaneously to rotate the reversal
roller. At the same time, the flapper solenoid turns ON to switch the reversal flapper over to the
reversal side.
When the exit operation is in progress, the transport stops after being driven for a specified number
of pulses. The original being feed pauses before the reversal section, and stands by for exit opera-
tion to complete.
After the exit sensor turns ON and the leading edge of the original is detected, the original is trans-
ported for a specified number of pulses.
(6) Completion of forward rotation transport
At the point where the leading edge of the original is nipped by the reversal roller lower passage roller
by a specified amount or more, the transport motor and the reversal motor stop.
