Note: During this procedure, you will be removing a number of
screws. Make sure to save these screws for future installation purposes.
Removing the support roller
- Quit the Magnus 400 Controller software and turn off the platesetter.
- To enable easy access to the rear of the punch conveyor (punch cover
side), slide the punch conveyor out from the punch conveyor guides (on
the rear of the platesetter), and then push it away from the platesetter.
- With both hands, lift the punch cover up and off the conveyor, and
set aside.
- Remove the four screws (two on each side) that secure the punch cover
frame to the punch conveyor, and remove the punch cover frame.
- On the left side of the punch conveyor, remove the two screws that
secure the support roller motor guard to the support roller and motor
bracket, and remove the guard.
- Loosen the two hex screws that secure the support roller motor to
the support roller and motor bracket.

- Slide the support roller motor backward in the groove (to release
tension on belt), and remove the support roller belt.
- Loosen the two set screws on the red support roller gear, and pull
out the gear. Set the gear aside.
- On the right side of the punch conveyor, remove the two screws that
secure the support roller bracket to the chassis and remove the support
roller assembly (with bracket).
Installing the support roller
- Insert the new support roller assembly (with bracket) and secure to
chassis with the two screws that you removed earlier.
- On the left side of the punch conveyor, push the support roller gear
onto the support roller and secure with the two set screws that you
removed earlier.
- Reinstall the support roller belt over the two support roller belt
gears (one on the support roller motor and one on the red support roller).
- Slide the support roller motor forward in the groove (toward the front
of the punch conveyor), and secure with the two hex screws.
- Reinstall the support roller motor guard.
- Reinstall the punch cover frame.
- Reinstall the punch cover.
- Push the punch conveyor back toward the platesetter. Use the punch
conveyor guides on the rear of the platesetter to align the punch conveyor
with the platesetter.
