Main, Sub Jogger

The following parts comprise the main jogger which operates the front fence and rear fence :

[1] Front fence motor

[2] Front fence HP sensor

[3] Rear fence motor

[4] Rear fence HP sensor

The movements of the front fence and rear fence during jogging (paper edge alignment) are controlled independently by two separate motors.

Unlike the main jogger fences the front fence and rear fence of the sub jogger unit are controlled by one motor, the sub jogger fence motor [5]. The motor switches on, and the belt drives the fences in. Then, the motor reverses and when the sub jogger HP sensor [6] detects the fences at their home positions, it switches off the sub jogger fence motor.

The main jogger also has a fence retraction mechanism that raises the front and rear fences after each set has been aligned. The main jogger fence retraction motor [1] switches on and raises both the front fence and rear fence together after the edge of each set is aligned. Then the motor reverses and lowers both fences, and when the fence retraction HP sensor [2] detects the home position of the fences, this switches off the motor. The sub jogger has no such mechanism.
