No waste toner - Brother MFC-8460N Laser Printer

the top of the waste toner container must be cleaned 100% from the toner because it should be a light sensor that has to pass through it , if its spoiled with toner the light cannot pass through it ,so i recommend you to empty the waste toner container first and wash it with water and drying it well before using it again.

1. Remove the full waste toner box per manual.
2. Wear breathing protection as there will be toner dust in the air.
3. Place flat in a work area and remove the 6 screws retaining the black box cover and carefully remove cover with box still flat on the work area. Be careful, the box is full of waste toner powder.
4. Dispose of the waste toner by tipping into waste container, being careful not to inhale the powder. Use a blower or vacuum to remove final traces of waste toner from the box and clean all surfaces with a clean cloth.
5. Place the box flat on the bench and inspect the clear sight-glass at the front. Inside will be a black flag which should be down on the bottom of the sight glass. If not, there is still waste toner in the front of the box which needs to be shaken or blown out.
6. Replace the cover and 6 screws and replace the waste toner box in the printer.
7. If error message still says replace waste toner box, then you need to check the sight glass again. The flag must be horizontal at the bottom of the glass or it is not completely empty.

When you removed the waste toner bottle, there is a sensor inside the copier. When you remove the waste toner, look to the opening where the top of the waste bottle was, clean that area and return the bottle and turn the copier OFF then ON. Good Luck

It seem that something is wrong with the fixing unit temperature. For reset procedure:

Actually, the waste toner should get full sometime before the regular toner runs out in laser printers that have several toner cartridges compared to the single waste toner reservoir.

You can dump the toner reservoir out and avoid buying the empty waste toner 'reservoir.'

I did this on my Brother Laser printer and saved about $30 or so for an empty plastic waste toner bottle or jar.

If this is the way the Kyocera-4020DN is, then I would put the waste toner, which is just that, waste, and put it into a plastic zip loc storage bag and throw it away. Don't breath the toner.

Good luck on this repair.

Open your user manual.

Or get one - go to google or samsung.

The life of the waste toner container unit is approximately 1,250 pages for full color 5% image printing or 5,000 pages for black printing. When the life span of the waste toner container has expired, Replace/Install Waste Toner Tank appears on the display of the control panel,
indicating the waste toner container needs to be replaced. Otherwise your printer stops printing.

To replace the waste toner container:

1 Turn the machine off, then wait a few minutes for the machine to cool.

2 Open the front cover.

3 Pull the waste toner container out of the machine using its handle.

4. remove the container cap from the back side and cap the opening

5. take the new waste container out of its package

You may wish to TRY EMPTYING the waste toner, but you will find toner is the messiest and possibly dangerous (inhallation, etc) stuff you've worked with. it is an extremely find powder and can cause an awful mess and is best disposed of by capping and replacing the container with a new one (shop around to find them).

DO NOT attempt to vacuum up toner - just my personal opinion - I suspect many vacuums may not have fine enough "bags" to capture this intentionally very fine dust. BUT Toner vacuums do exist and some "may" work.

sir,

You open the front cover, there you can see the plastic bag. on the side of the cover you can see the intruction regarding the removing and refixing. actually it will be in white like colour and having a black bottle cap.

And also after you taken the waste toner catridge. you can see one sensor below a pipe like that which is projecting from the drum unit , it is the waste toner path. Inside this the waste toner auger will be there. you just clean the sensor because you may also get the waste toner error by the sensor.

1. sensor below the auger after the waste toner catridge.
2. waste toner catridge outside and inside. dispouse the toner and also clean the otside part will cloth , beause some projections some holes like that will be there. i told na that sensor will be passing the signals through this waste toner catridge projection. If any toner in that projection then also the same. Be causreful while you are disposing the toner. You may intake and also your properties may be having the black coating like that.

any clarifications mail me at ramanathanr@integramicro.com .

When you open the door to access the toner and waste toner area, you will see a letter "K" on the left side of the waste toner box, and a thumb screw on the right side of the waste toner box. Immediately above the letter "K" there is a raised area in the brown plastic housing. It is between the blue toner cartridge, and the waste oner box. There is a second raised area 2.5 inches at a 225 degree angle below the thumb screw on the right side of the waste toner box.
If you will place your thumbs on the raised areas and your forefingers on the white plastic rear cover of the waste toner box immediately below the raised areas and squeeze your fingers towards your thumbs, the waste toner box will come forward at the top of the box. You can then lift the waste toner box up and out of the printer.
Please squeeze carefully if you think your waste toner box is close to full as you may inadvertently find waste toner all over the place.
The two blue caps on the back of the waste toner box are to keep the waste toner in the waste toner box instead of your carpet.
Installation of the new waste toner box is the reverse of the above procedure. The new waste toner box almost snaps in place.
Here in California waste toner is considered a hazardous material and must be disposed of properly.

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.
