CHAPTER 2 OPERATION OVERVIEW
2.5 Controlling the knurled belt
2.5.1 Overview
The primary function of the knurled belt is to ensure that sheets delivered to the process-
ing tray are drawn all the way to the stopper. When the shape of the knurled belt is normal,
the contact pressure the knurled belt applies to the stack varies according to the thickness of
the stack in the processing tray. Changes in the contact pressure interfere with proper con-
veyance of the sheets. Therefore, in this machine, the contact pressure of the knurled belt
does not affect the thickness of the stack, rather the normal pulling force on the belt alters
the shape. The amount of pulling force on the belt is exerted by the pulse control of the
knurled belt motor (M20).
