You need to replace the waste toner tank.Open the front cover and on the left side in the gray waste toner tank. You can pull it out and replace it with an empty one or you can try to empty it and reinstall the tank. If you empty it, you have to make sure the parts of the tank where the sensor checks to see if it is full is clean. Otherwise it will generate the same error again. You need a cotton swab to clean the sensor ports of the tank so that the light can shine into it. Hope this helps.

Tried everything, this is the simplest and it WORKS on Samsung CLX-3175: fill up the bottle half-way with alcohol, shake it to dissolve all ink, pour it out, let it dry over nite. The bottle looks completely clean and clear like new.

Cleaning my tank had no effect so decided it was the sensor.i changed the sensor on the imaging for a spare luck, so it must be the other end(in the printer casing) ...the light emmiter that the sensor is trying to "sense". instead of changing this... remove imaging unit, remove tank and toners, undo 2 screws inside where the toners go and unclip the outer casing of the unit. in there youll see the sensor, remove it by uncliping the circuit board, srtip some insulation of both wires and twidt together, insulate with tape , plug back in , put all back together...worked a treat for me.

SOURCE: waste toner tank

A few things can cause this.

The way the printer determines whether the waste tank is full is via 2 optical sensors, one on either side of the tank. You'll see a rounded bulge on one end of the tank - the sensors are on either side of that, when the tank is installed. Under normal operation, light passes through that and the printer reads it as meaning the tank is not full, until the tank fills far enough to fill that bulge, and thus block light and give a tank full reading.

If the tank gets too dirty, not enough light passes through and it gives false tank full readings. So the first thing to try is cleaning the tank with soap and water. Make sure that area is as clear as possible.

If that doesn't work, it has also been reported that the sensors themselves are unreliable. I am told Samsung will replace the sensor for free if it's been less than 3 years. If you call them, insist that it is the sensor that is the problem, or they will try to get you to replace the waste bin, at your expense, first: 1-800-726-7864.

Alternatively, you can remove the sensor from one side, and reattach it to the other side - putting the two sensors in contact so that they always read an empty waste tank. Do this at your own risk, however, as you will have to check the tank regularly and make sure it doesn't overflow. Doing this bypasses the sensor, so there is no longer any warning if your tank is overflowing.

Hope some of that helps you.

SOURCE: waste toner tank full/not install keep displaying

The sensor itself weren´t dirty, but plastics in waste toner tank was bit dusty and sensor couldn´t read through it. So I modded waste toner tank a bit with a knife (took the part away which the sensor uses when reading if it is full or not). And works again beautifullu.

All I have to do know is to take care of waste toner tank manually i.e. checking it every now and then and when it becomes full I throw it away.

SOURCE: Error Message--Waste Toner Tank Full/Not Install

I did cleaning, drying, etc. as mentioned by caaa, but no result. After noticed a square hole on a waste tank which has to slightly push the black plastic arm in printer by inserting the waste tank. But there is missing something (I don't know the reason, if dropped out, or...) that is over hole about 5mm. Fix this missing distance with small wire (e.g. chipped proper rounded part of paper clip) fitted into the hole. Carefully check if the wire is not big too much, not to brake the arm. Works until now.

Wash it out with rubbing alcohol and let dry. Apparently there is a light sensor that will throw up this error if the bin is dirty.

SOURCE: Replace/Install toner waste bin error

The toner box is probably full. The toner box is a clear box on the left side when you open the front cover. The box has the labels Y, M, C, and K on it. Pull it out using the tab at the bottom. find a place to empty it. You can do this by turning it upside down and gently tapping it. If the box is full some toner may be outside of the box causing the sensor to be blocked even after it is empty. You may want to clean the box, toner cartriges and inside the cavity with qtip, tissue paper (without lotion), or air.

Printer gives error message "install toner"

Hi Steve,
The waste toner tank is the gray L-shaped container to the left of the cyan (blue) toner cartridge. Pull on the tab handle and either shake out the waste toner into a deep trash can (VERY messy) or outside into a trash can, then replace the old one if emptied or use a new one. Should be able to get it at a larger office supply store. Hope this helps.

Waste Toner Error Message For Samsung CLP 550

Dr. P,
Printer will display "Waste Toner Tank Full/Not Installed" error message if the waste tank is full of toner or not installed.
  • Open the waste tank door and check for the waste toner tank.
  • If the tank is full or not intalled, install a new tank.

If you have user guide, it will show you how to install the waste toner tank.

Sometimes you will also get this error message if the Waste Toner sensor is covered with toner powders.
  1. Remove your waste tank and look for the black plastic on the right side after removing the waste tank.
  2. You sould find small openings on each side in the black casing.
  3. Use Q-tips or thin cotton object to clean the inside the small opening.
for user manual just click here:

If this solution works, please don't forget to rate it fixya

For any more question just ask me.

I keep cleaning the toner/printer waste tank cartridge and the printer continues to stop printing and the same error message displays saying "Replace/Install waste toner printer cartridge.

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.

Hope this helps.

CLX 3160 waste toner tank error message

Empting the waste toner tank does not always fix this problem. Samsung shines a light through the tank with a photo receptor on the other side. If it the photo receptor does not see enough light, it will trigger the replace waste tank message.
You can fix this by trying to clean the clear window portion of the tank with a q-tip. This is difficult to do since there are parts of this window which is hard to clean with a q-tip.
Or you could wash it out with soapy water until the window is clear of toner. Allow the tank to dry and reinstall.

Waste tonner tank

The waste toner container is inside the front cover at the bottom right. If you work for a business you should purchase a new one. If not you may be able to empty it into a another container and seal it before putting into the bin.

We removed the waste toner bottle and it won't reset the error message

You will need to vacuum all the toner out as in the machine there is a sensor that looks through the waste tank and checks that it is clear. You can also wash the tank out then install it and you will not have the problem.

Waste motor error

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.

Error Message--Waste Toner Tank Full/Not Install

What I have started to do is to actually wash the toner tank out with water and make sure it is good and dry then be sure the section that breaks the light sensor is good and clean (it is on the left side as you look at the backside - the side that goes toward the printer - and protrudes out) the tank full indication comes on when the tank gets dirty
