■ Pre-registration Roller Disengage Control
At the skew correction on the active registration area, the pre-registration roller 1 and 2
interrupt so that the disengage control of pre-registration roller 1 and 2 is executed.
They are engaged at a normal status and when the skew correction is started (when the
leading edge of paper goes through the primary skew sensor), they will be disengaged.
