Canon 2035 imagerunner developer is empty but the bottle is full

SOURCE: Used Toner Bottle Full Ricoh Aficio 1035P

The used toner bottle is not actually a bottle at all. Not sure what you emptied, but it sounds like the actual toner bottle itself. The waste toner is contained with in the transfer belt unit. When you open the right side cover, this is the unit that is attached to the door. It is a brown belt that provides transfer of the image to the drum and separates the paper from the drum. Remove this unit by locating the release levers on either side of the transfer unit (push both of them towards the machine). After removing, you will need to actually take the belt unit off of the transfer unit. To do this, remove the two tension springs on either side, and then take a small flat bladed scredriver and release the clips that hold it down (you will see when you get started). Once you get it off, you will see the long blade that actually scrapes the toner off the belt. Dump the waste toner out this end. You will need to shake it pretty hard. A better (and cleaner) option is to vaccum it out using the crevace tool on you vac. Just make sure you completely empty it. Now....do everything in reverse.

Hope this helps,
Chad

hi you have a waste toner error code, the waste toner is apart of the drum unit in these machines so you will need to order a new drum unit for it.
easiest way to fix the problem.

I am not familiar with this model but usually Canon waste bottle has:

1. Check if the waste toner botlle has some clear portion near the neck, (as in IRC3200) or other part of the bottle ,even the waste toner was removed but if this portion is still clouded by toner the sensor will still detect the waste is full

2. If the situation is not like this some Canon Ir machine needs to reset waste toner counter in the service program mode even the waste toner bottle was emptied
