Installation notes:
•
Make sure the springs are resting on the frame so they can be positioned once the new fuser is in place.
They can be difficult to reach if they hang down.
•
Be careful not to bump into the fuser exit sensor on the left side.
•
When reinstalling on the right side, make sure the gears mesh.
•
Reroute the cables back through their retainers (A, B).
•
When you replace a new fuser, be sure to reset the Fuser Page Count.
