Waste toner receptical problem

Typically you will need to replace the waste toner box. There is usually a difficult to access part of the bottle that is used by an optic sensor to tell when the box is full. Plus toner is very fine and you do not want it getting into the air. Toner will pass through the filter of most vacuums and go back into the air.

then the clear section of the waste toner bottle is not clear some toner is left blocking the sensor that monitors the waste toner level

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

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....

The clear section of the waste toner box where that goes inside the machine check that area sensor located there might have toner on it so the printer thinks the waste toner box is full

The trick about cleaning out the waste toner container is you have to also swab out the clear plastic piece the optical sensor reads so the device knows the waste toner is full. Clean that out and you should be able to get more than a weeks usage out of the waste toner container.
Hope this helps.

waste toner is full.replace the whole drum unit

I assume when you say you dispose of toner you are emptying out the waste toner bottle and putting it back in the machine. if so here's your problem.
There is a sensor, mounted to the copier, just behind the waste toner bottle (on the upper righthand side). This sensor shoots a beam of light through a small portion of the waste bottle - if the beam is not received on the other side then the copier thinks the waste bottle is full. NOW...even if you have emptied it the interior of the bottle may still be dirty/black enough (leftover residue) to stop the beam from making it through the bottle - this gives you the message. You will need to put in a new bottle.

hey, wel if the copier is showing a message saying that the waste toner is full it means the waste toner deposit is attached to the drum unit.

so, open up the frotn cover, pull down the (drum)-lock lever, it should release the left cover, then pull towards you the drum unit, and there you go.
the black case with a small trasparent cap is the waste toner deposit.

you have two ways to go.

1 you may remove that rounded transparent plastic cap and be able to vaccum the waste toner (dont even try reusing that toner, it wont work ok) or

2 you can go the other way wich allows you to easily vaccum it: remove the drum (the roller itself) then the charger roller, then the cleaning blade and there yo go again, but now you got more space to vaccum and believe me it is easier this way.

an additional choice would be to buy a new drum unit gpr18 i think (check please) and forget all about vaccum-ing.

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.
