The Waste Toner Cartridge must be VERY clean, especially around the "bump" directly below the left side hole. After I CAREFULLY emptied the old toner out, I used air compressor to clean every bit of toner out from inside. Then I wiped the whole area around the "bump" where the sensor "sees" if the tank is empty. Even a slight film over the area will not allow for reuse. If you do this, it works every time.

Then you mite want to clean the sensor that monitor the waster toner box pull out the waste toner box and look for the area that show clear plastic then look for those area of the machine and blow the old toner from those areas waste toner mite have gotten on the sensor saw they can not see the clear plastic and think that the waste toner cart is still full.
How are you cleaning the tank? Just dumping the contents into a trashcan may not work. The printer uses a light sensor to detect whether the tank is full. When the light does not shine through the clear window of the tank, the printer thinks that the tank is full. Sometimes cleaning the window with a cotton swab will make it work, but it can be difficult since the location of the window with respect to the opening of the tank is not a straight shot.
Another way to clean it would be dump the waste toner into ther trashcan. Tap the tank a few time to get as much of the toner out. Then add some soap and water into the tank and seal the tank opening with the green lid. Then shake the soapy water in the tank for a about a minute. Then dump the soapy toner/water out. Rinse again with just water and and allow it to dry. You don't have to get the tank completely clean, just enough to stop the waste tank error message.
You can either dump out the waste toner into a garbage bag, or replace the whole toner collector. If you decide to dump it out yourself, you need to make sure that the container is extremely clean prior to reinstalling it into your copier, as sensors on the copier end detect the level of used toner by optic sensor.
The waste toner tank may be full. Please open the front cover( where the toner bottles are located). You will find a transparent "L " shaped box is the waste toner tank. You may pull it out and replace it.
The wate motor transfers (you guess it) waste toner to the waste toner bottle. If the bottle fills up, the motor cannot transfer more waste to it. This is rare, for the printer should ask for a new waste toner bottle when the previous one fills. However,it happens frequently when users try to empty and clean the bottle instead of replacing it.
If a new waste toner bottle is in place, then the printer needs a new motor, which can only be purchased through an Authorized Service Center.
The sensor for the waste toner tank is dirty or defective. The toner sensor is on the right as you look at the panel just below the liquid crystal display. There is a bump in the clear plastic just below the circular right vent port, that's where the used toner pours in. When you clean out the toner cartridge there is some residue left that makes the sensor think it's still full. Take a piece of paper towel and a small screwdriver (I'm told a bent coat hanger will work, too) and clean the inside of the sensor window inside the used toner cartridge (w/ access through the toner port). It looks like a little raised groove on the right. Just wipe it until it's clear on the inside. The sensor can now see through the window and you should be okay.
Otherwise, the sensor may need to be replaced by an authorized Samsung technician.
Let me know how it works out!
