2.6.9 PAPER SIDE FENCE MECHANISM
The left and right side fences move together due to a rack and pinion mechanism.
The actuator plate [A] is attached to the rack. This actuates the paper width
detection board, to detect the position of the side fences (see Paper Size and
Paper End Detection).
The side plate friction pads on the front and rear paper side fences prevent multiple
feed. These are especially useful when thin paper is used.
There are two spring plates [B] applying pressure against the racks (one spring
plate each for the right and left racks). Normally, there is no pressure applied to the
racks. However, during long copy runs, the side plates may move away from the
sides of the stack. By adjusting the position of the spring plates, the side fence
pressure can be increased.
