Loop control

• All papers are passed through the loop roller and conveyed to the registration roller.
• Loop motor (M31) that drives the loop roller stops after specified time passed from when the registration
sensor (PS22) turns ON upon detecting the leading edge of paper.
• Because the registration motor (M30) is stopping, the leading edge of paper is pressed against the registra-
tion roller that is not moving. The paper forms a small loop before the M31 stops.
• Making paper form a loop enables to correct skew of the paper.
