Toner dumping straight into toner bag

Open the front of the printer, and you will see the four toner drums; cyan, magenta, yellow and black. Immediately to the left of the cyan drum there is an "L" shaped drawer : That's the waste toner drawer. It pulls straight out. If you enjoy driving around and spending money, you can buy a new one. If you are frugal and practical empty it as follows:
To do this cleanly I recommend wearing a pair of latex gloves! At the top of the container there is a square opening with gray foam on the inside edges - this is where the toner can be dumped out. Take an empty bread or bagel bag and put it over the end of the cartridge far enough to cover that square hole plus another inch. Gather the end of the bag and secure it with a rubber band or tape making sure the hole of the cartridge is INSIDE but not taped shut, and the bag's edges are properly sealed. Now you can turn the cartridge upside down and agitate it in different positions until all the toner is dumped into the bag. Flick the bag with your fingers to let the toner fall to the bottom, them put around the bag to keep all the toner at the bottom, and carefully remove the tape or elastic. Using a lightly moistened paper towel clean up the cartridge and reinsert it into the printer.

Now if you haven't left too much air in the bag gently take the end with all the toner in your palm, gather the rest of the bad with it into a small ball in your fist and pull your glove off over the whole lot. take that in your other hand and remove that glove.
Voila! The cleanest toner dumping ever!

replace the ic of toner cart. problem will be solved

Your user manual should list a "Clean Drum" command on the menu of the printer. If you don't, you can purchase laser jet cleaning sheets at any office supply store.

U need to check the developer unit see whether the developer material is dirty or uneven.

Wash out the bottle with soap and water.

Did you replace the waste (used) toner cartridge or the empty toner cartridge? These copiers have 2 "cartridges" .... one is waste (used) toner, the other is "new" toner for copying / printing etc. Some newer copiers have All in One units....Drum, New Toner, Waste (used) Toner. If you replaced the Waste Toner container (or dumped it) that should reset the code or error message.

yes - pull it out - twist the lock closed - tip upside down and shake it into a plastic bag - it will get awfully messy if you don't use the plastic bag.

Use your hand and tap the tube going to the used toner bag. Does it sound full? sometimes the toner will clog the tube and back up. You need to knock it loose so that the waste toner will empty. Also check the waste toner bag switch, it may have gotten knocked out of position when removing it the first time. If so just reposition and / or reshape.

Hi,
The developer should be change by a tech. You have to dump the old and replace with new and then set the developer calibration. Waste toner is right in front, a black container that you remove, dump, then put back in place, try to do that each time you add toner so that it never fills all the way full.
