That model, as most Ricohs, uses the ID sensor to determine when and how much toner to add. I would check to make sure it's clean, no toner or paper dust. If that's not it you might need to replace it.The ID sensor is located in the PCU, facing the drum.Good luck. If this helps, please remember to rate this. Thanks

My ricoh mpc 2500 keep saying add black toner whereas there is toner in the toner bottle


If asking for black toner did you change rt toner pump should been one behind the black dev unit. Sometimes when you change it might have to open and close front door. A couple of times make sure you leave it open long enough that it think you change bottle

Add toner problem


If it is not adding toner there could be 4 possible causes, 1.make sure all the covers are closed, if they are not then the machine will not "run" to add toner. 2.Did you check to make sure there is enough toner in the toner bottle. 3. when the machine starts running/adding toner, can you feel a vibration or hear noise like gears grinding/slipping, if so, call a technician to replace drum/dev gears.4. when you open the toner tray/harper/hopper, at the bottom there is a flat silver sliding plate, when you slide it open, is there toner falling oout of that hole, if not, ask a technician to strip and clean the toner tray/harper/hopper.

Dev. Change Process

1. Check that Dev. unit has the lastest seals.
2. replace dev. material.
3. Dump dev.
4. add new dev. material.
5. Hand rotate the dev. unit 10 times.
6. reinstall the dev. unit into machine.
7. cover the toner inlet opening with a piece of paper
8. insert PCU unit.
9. turn the machine on.
10. When machine reaches ready -- enter SP modes and perform SP-2801 (2 times)
11. open the right cover of the machine. Cheat the right cover switch. Examine the drum as it rotates. Afew bands of toner and the ID pattern will be developed on the drum. The drum should be clean -- a slight dusting on the drum is OK.
12. Perform SP-3001 -- ID sensor initial setting.
13. ** Important** remove the PCU unit. Empty the toner from the PCU by sliding the shutter on the bottom of the PCU to the side and tapping the PCU.
14. reinstall the PCU.
15. Run test copies.

Pls rate -- thank you

Open the front door and close it and check if the display reads loading toner. Try this for 3 times.
If Add toner indicator is still there, check that you had removed the black cap of the toner, before you replaced the toner bottle.
Remove the bottle from the holder and check inside the neck of the holder if there is something blocking the toner supply. (sometimes the inner plastic cap of the previous toner is stucked in the neck).
Check and clean the toner bottle holder unit.
Another problem can be worn gears in the lower development unit and within the dev. bias roller.
Good luck and please rate me, thanks.

ADD TONER BLACK


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
Hopefully then you will add toner if not the likely thing is that the developer unit will need replacing.

Hope this helps
Thanks J
