Inverter Operation
Inverter Feed-in and Jogging
Just after the main switch is turned on:
• Jogger motor [D] (a stepper motor) moves the jogger fences [C] to home position (determined by the
duplex jogger HP sensor [E]).
When the Start key is pressed:
• Motor [D] positions fences [C] 20 mm away from the selected paper size to wait for the paper.
• Inverter entrance roller [A] feeds paper to the jogger section. Then the paper pushes down the gate
[B].
After the paper passes through the gate:
• Motor [D] (a stepper motor) moves the jogger fences [C] in to square the paper. This happens every
page.
• After this, the jogger fences move back to the previous position (12 mm away from the paper)
• A spring pushes the gate back up again after the paper has gone (there is no solenoid).
