Paper exit decurler roller pressure control

A. Paper exit decurler roller pressure mechanism
• The paper exit decurler roller [1] that faces to the paper exit roller is pressed by the rotation of the cam [2].
• The cam is driven by the paper exit motor (M54).
• Forward rotation of the M54 causes paper exit operation, and its reverse rotation moves the cam to apply
pressure to the paper exit decurler roller.
• The cam and the encoder [3] are located on the same shaft. Paper exit pressure sensor (PS10) [4] detects
the slits on the encoder in order to determine the home position of the decurler roller.
• The pressure applied to the paper exit decurler roller is changed by the cam position in four levels; release
[8], low pressure [7], middle pressure [6], and high pressure [5]. The pressure level is controlled according to
the time period of the M54 rotation from when the PS10 turns off.
