Warning!

If the printer has recently been powered on, some

fuser components will be very hot. Handle the fuser

with extreme care, holding it only by its handle, which

will only be mildly warm to the touch.

A warning label clearly indicates the area. If in doubt,

switch the printer off and wait at least 10 minutes

for the fuser to cool before opening the printer cover.

1. Press the cover release and open the printer's top cover fully.

2. Note the positions of the four image drums: Cyan (1), Magenta (2), Yellow (3),

Black (4). It is essential that they go back in the correct order!

3. Lift each of the image drum units out of the printer and place them in a safe

place

4. Locate the two blue locks (1) and the handle (2).

5. Turn the two locks about 45 degrees counterclockwise to release the belt.

6. Pull up the handle and lift the belt unit out of the printer.

7. Unpack the new belt unit and hold it with the blue handle toward the front of

the printer.

8. Place the drive gear at the back of the belt unit in the gear at the left rear

corner of the printer, and lower the belt unit into the printer.

  To address frequent paper jams in your Oki Printer, ensure the printer is on a stable, level surface and that you're using the correct type of paper. Store paper within specified temperature and humidity levels. Remove any creased or wrinkled paper, and adjust the tray or manual feed guides. Also, verify the correct paper feed selection in the printer driver's Properties Setup tab.
