Skew Correction - Ricoh BR-C1a Basic Service Training

 When skew correction sensor [B] detects the leading edge, the
original continues to feed for a set number of pulses.
 Then the leading edge hits the pull-out roller [C] and grip roller,
which has stopped to align the leading edge and correct skew.
 During duplex scanning, or if the original is small (B6, A5, B5,
HLT), after the scanning entrance sensor [E] detects the leading
edge of the original, the scanning entrance roller [D] stops for a
set number of pulses for the second skew correction.
