Registration mechanism
• For punch and holding operations, a loop is formed in the paper at the Registration Roller [2]
to correct skew of the paper.
• The Entrance Sensor (PS4) [1] detects the leading edge of the paper and the Registration
Roller forms a loop in the paper.
• The Registration Clutch (CL1) is then energized after a given period of time after the PS4 is
activated by the leading edge of the paper, this causes the Registration Roller to start turn-
ing.
