The waste toner box collects residual toner that is produced during printing. When the used toner box is full, the display 
will show "Replace used toner container.". Follow the procedure below to replace the used toner box.

Press the waste toner box release button.

The waste toner box will fall forward as shown at left. Wait until 
the box comes to a stop.

Keep the replacement cleaner that has not been used.
Store it at the top of the waste toner box.

Hold the box by both hands and lift it up slowly.
If the waste toner box falls too far forward, it will not be possible 
to remove it. (Remove the box when it is at an angle of about 
30 degrees.)
