Did this clear the error?
Note: If you have already tried powering the printer off and on, then skip ahead to Step 2.

Power off the printer/MFP again and open the front door assembly. Then open the standard media tray.


Inspect the waste bottle for damage or excessive toner contamination. If the bottle is fairly new and almost empty, it may be possible to dislodge loose toner carefully from the inner walls of the bottle by lightly tapping the sides. This should allow any toner stuck to the bottle walls to fall into the bottom.
Note: If damage exists, replace the waste toner bottle.


Close standard media tray, and then close the front door assembly completely.
Note: Ensure that the waste toner bottle is installed correctly. Push on the left bottom of the bottle to ensure its proper seating.

Power on the printer/MFP again.
