Add toner problem - Ricoh Aficio Mp2500 Mp2000 Mp1600 3030 Brush Roller

SOURCE: message says to add toner after I replace toner

1. Open front door and pull out toner hopper.
2. Remove toner and make sure it still hase the clear cap on the top fully inserted in the bottle. If cap is missing and you can see the toner in bottle, it's a lost cause get a new toner bottle.
3. Lay toner bottle in hopper and push toner hopper in the machine while keeping the green latch up all the way through the pushing motion. This is critical to ensure the cap will come off. Once toner hopper is pushed all the way in, push the green lever down. Again it is mportant to mention that the gree lever must be up till the toner hopper is ushed in all the way. Then and only then the green lever may be pushed down.
4. Allow machine to load toner.
5. If it still says add toner, open and close front door. Again allow machine to load toner. You may have to do this up to five times (open and close front door) to replenish the deleoper unit with toner.
This problem is common with these machines if you do several copies of a dark original or print. The developer gets depleted of toner, it just cant keep up and then the machine says add toner.

If the toner is an original you should not have a problem unless the Developer unit is faulty. The developer unit mixes the toner with the dev. If the dev unit TD (Toner Density) sensor is not working then it will not add toner. Try the following.

• Remove black drum unit
• Remove Black Developer unit
• Tap the develop unit and shake side to side 5-6 times
• Reinstall both units close covers and open toner cover
• wait 15 seconds then close the cover

Thanks Ricohman for the suggestion. Toner was original Ricoh cartridge and reinstalling it didn't help. I decided to tear the machine apart and discovered the auger for the black toner was stuck. I removed the auger, cleaned everything up and put the machine back together. Works great now.

I have changed the toner cartridge and the sign to add toner is still on.
