Toner Box full when its not - fault

Printers usually have a waste collector where excess toner is collected. Obviously, yours needs to be changed.

If your machine is displaying "replace waste toner container" then you can empty the waste toner box & reset the machine.
If you open the front door you will see a large black box & above this a small rectangular green button. Pressing this button will release the black box. The box will then lift upwards from the machine. At the bottom of the box you will see a round, clear plastic bung, remove the bung & empty the waste toner into a suitable bag or container. Once emptied, the bung can be re-fitted, the waste box can be inserted back into the machine. Locate the waste box into the 2 slots then push the waste box firmly back in place until it latches. Turn the machine off & on using the switch located to the left of the waste box in the bottom left corner of the inside of the front door. This should reset the machine. Be careful when disposing of the waste toner, it is flammable so do not dispose of in a fire. Hope this helps.

The collection box for waste toner. When making a copy or a print not all of the toner that is put on the drum gets used, during the cleaning stage of the process that very small amount of toner is removed and sent to the collection box. Depending on your make and model there is a scheduled image count that the box is replaced or emptied at. If you try to empty it yourself be careful!!! Toner is the finest dust you have ever seen and can become a large cloud in the air (landing all over the place) if not handled properly. And yes it will go through a vacuum cleaner bag and into the motor. Service techs have vacuums that are made specifically for toner.

If you can not rotate the toners by using the DISPLAY MENU,

You can rotate them MANUALLY, using a flat head screwdriver or even a key for your car or front door.

Open Front Cover/Door of Printer

Remove Waste Toner Box

Where you see the side of the Blue Cartridge, look to the LEFT and locate a small rectangle with a circle inside it.

Push your car key or flat head screwdriver into this rectangle and the circle will push back and release the lock on the cartridge, holding in with one hand and turning cartridge with the other hand until you get the cartridge you want to replace.

Remove the screwdriver / car key and pull out the empty cartridge and replace with new one.

Replace Waste Toner Box, close front cover/door, switch on and the printer will rotate back itself to it's normally position...... JOB DONE

like the name suggest, it collects waste toner. Any toner that is left over from the print process is waste toner. Once the waste toner bottle is full, the printer will stop working until You have replaced it with an empty waste toner bottle. So in short, if it is telling u to get a new one, get one or the other option is to empty it yourself which is very messy and if u dont clean the bottle of all toner dust, may not even work.
