You have to empty out the waste toner bottle... The bottle is a milky white plastic and I believe it is right under the fuser unit. It should slid out toward you. Carefully dump the toner out of the bottle into a plastic garbage bag and re install the bottle and you are done....
not a solution - but a problem... i emptied the toner waste bottle in my MPW2400 and a new error message appears...says there is no toner and it keeps dumping toner from the new cartridge until it is coming out of every orifice of the machine. What is that about?
You have to "tell" the printer that you have "emptied" the receptacle. Depending on the model of printer, you may either need to replace it, or use the controls on the printer to "logically" do a "reset" operation.
It's not recommended to empty this as it contains 4 colored toners and you would heve to ensure that the light sensor sees completely clear in the view area. Replace the bottle with type 155 waste toner bottle (about $25) from on line supplier. To do this is simply a matter of opening the right side cover and sliding the green lock lever to the unlock position. Then remove the bottle and replace. Don't forget to slide the green lock lever to the lock position and close the cover.
Couple of things to try:
- If you just emptied the waste cartridge then you have to take the bottle back out and clean the insides as well. The sensor sees the toner on the walls and still thinks it?s full. FYI as typical the manufacturer recommends replacing the bottle with a brand new one.
- If not that then you may have toner covering the optical sensor. Try blowing the area where the waste bottle attaches to the printer with canned air.

The waste toner is usually a bottle near the toner cartridge which collects excess toner powder from the cartridge. It is usually present in more heavy duty laser printers, not all printers have them as a replaceable supply. You would need to refer to your manual for replacement instructions, they vary from printer model. For this machine, the Waste Toner supply number is #420131.
In the case of the first poster, my best guess would be there was spillage of toner on the sensors to detect the waste basket overflowing, hence why the error message is constant. This would require cleaning of the sensors, a relatively simple task but for proper access, the machine would need to be partially disassembles for thorough cleaning. It would be best done at a repair centre.
