C. Loop formation mechanism
• The paper passed between the paper feed roller [5] and the separation roller [3] is conveyed to the pre-reg-
istration roller [7].
• The paper pushes the actuator [1] and the actuator turns on the paper feed sensors /1 (PS29), /2 (PS35)
and /3 (PS41).
• In order to correct skew of the paper, the leading edge of the paper is pressed against the pre-registration
roller that is not moving until the paper forms a small loop [2]. This is made by stopping the paper feed roller
after the specified time passed from when the PS29, PS35, and PS41 turn on.
