A typical Xerox Phaser 4510 maintenance kit includes the following parts:

1 fuser

1 transfer roller

12 paper feed rollers

Replacing these parts are fairly straight forward and can be done even if you're not mechanically inclined.

1. Power OFF the printer. Press the power switch that is located on the front of the printer, on the bottom left side, to the (O) position.
   
   
    
2. Disconnect the power cord and allow the Fuser to cool for 30 minutes.
3. If installed, push up on the Duplex Unit release button to open the unit on the back of the printer.
   
   
    
4. Lift up the Rear Cover release lever to open the cover.
   
   
    
5. Press down on the two orange latches on the bottom, left and right sides of the Fuser to unlock the Fuser.
   
   
   
   NOTE: Do not adjust the position of the green latches on the top, left and right sides of the Fuser. The green latches are used to help remove paper jams.
    
6. Grasp both sides of the Fuser and then pull evenly on both sides to remove the Fuser from the printer. Do not use the green latches to remove the Fuser.
   
   
   
   NOTE: Use the box that the new Fuser is packed in to pack the used Fuser.
    
7. Remove the new Fuser from the shipping packaging.
8. Slide the Fuser into the printer until the two triangle points on the right are aligned, and then lift up the orange latches to lock the Fuser into place. Make sure the latches are fully locked.
   
   
   
   NOTE: Do not force the latches into place. If one or more of the latches will not easily lock into position, make sure the Fuser is the correct Fuser for the Phaser 4510 printer. 
    
9. Close the Rear Cover.
10. If installed, close the Duplex Unit.
11. Connect the power cord, and then power ON the printer. A 'Ready to Print' message will be displayed on the Display Screen.

    1. Press the [Up] or [Down] arrow button on the Control Panel until 'Information' is selected on the Display Screen, and then press the [OK] button.
       
       
        
    2. Press the [Up] or [Down] arrow button until 'Supplies Info' is selected, and then press the [OK] button.
    3. Press the [Up] or [Down] arrow button until 'Reset Fuser Life' is selected, and then press the [OK] button.
    4. Press the [Up] or [Down] arrow button until 'Reset Fuser Life Now' is selected, and then press the [OK] button.
