6.13.4 PAPER FEED AND SEPARATION MECHANISM
Feed and Separation at Standby: No Paper Present
While waiting for the first sheet to feed and between sheets, the feed roller [A] must
not rotate. However, the grip roller [B] must turn, so that any paper coming up the
vertical transport path can continue to feed. To do this, the paper feed motor [C]
rotates in reverse. The feed roller cannot turn because of a one-way clutch. The
separation roller [D] is free to rotate in the direction shown by the arrow, because
the separation roller solenoid is OFF.
When the feed motor reverses:
Feed roller [A]
Æ
No rotation
Separation roller [D]
Æ
Free to rotate
Grip roller [B]
Æ
Rotates
The feed motor cannot be replaced easily. Because of this, an assembly is
available as a spare part.
