My copier ran out of toner, I replaced it with a new unit, it still says add toner 100%, I even changed the used toner bottle. Please help, this is the only unit we have at the station besides the fax.

Take out the toner cartridge and shake it vigorously. When they sit for a long time the powder tends to clump.

please check if the toner is not lumpy cos this can also cause that.
or also check the buttom of the toner bottle since the moto and the bottle may not have the same format .

Mam, First remove the toner bottle. Turn of the power. Then turn on the power. without he toner bottle in the machince. Let the machine then run thur its normal program. When the machine asks for a new toner install the bottle. Also check the toner bottle, ensure the nub that sticks out is not damaged if it is dented in anyway replace with a new bottle. That nub is what toner motor uses to turn the bottle, if damage the motor will not get a good whole on the bottle. If that does not work you may need a new image unit.

I reproduce below the content from Ricoh official website. The instructions to install toner cartridge are as follows:

Note: You can make about 50 copies even after the Add Toner indicator begins flashing, but replace toner early to prevent poor copy quality.
Please read the following warnings and notes before attempting to add toner.
WARNING

• Do not incinerate used toner or toner containers. Tonerdust might ignite when exposed to an open flame. Dispose of used tonercontainers in accordance with local regulations.
• Keep toner (used or unused) and toner containers out of reach of children.
• Iftoner or used toner is inhaled, gargle with plenty of water and moveinto a fresh air environment. Consult a doctor if necessary.
• If toner or used toner gets into your eyes, flush immediately with large amounts of water. Consult a doctor if necessary.
• If toner or used toner is swallowed, dilute by drinking a large amount of water. Consult a doctor if necessary.
• Avoidgetting toner on your clothes or skin when removing a paper jam orreplacing toner. If your skin comes into contact with toner, wash theaffected area thoroughly with soap and water.
• Iftoner gets on your clothing, wash with cold water. Hot water will setthe toner into the fabric and may make removing the stain impossible.

To replace the toner, follow these steps:

1. Keep the device switched on and only add toner when "Toner is Almost Empty" is displayed
2. Open the Front Cover
   
   
   
   
3. Lift the large green handle up to its full extent
   
   
   
   
4. Press and hold down the green lever to the left of the green handle
   
   
   
   
5. Use the green handle to pull out the Toner Tray slightly then release the green lever
6. Pull out the Toner Tray to its full extent
   
   
   
   
7. Push the neck of the Toner Bottle back towards the device until you can see the top of the bottle
   
   
   
   
8. Lift out the Toner Bottle by the neck - being careful not to scatter loose toner
   
   
   
   
9. Dispose of the Toner Bottle in accordance with your local environmental instructions
10. Obtain a new Toner Bottle and shake it gently from side to side at least 5 times
11. Remove and discard the black cap and place the Toner Bottle in the tray with the neck towards you
12. Push the neck back into the black housing of the tray
    
    
    
    
13. Push the whole assembly back into the device until it clicks into place
14. Push the green handle down fully and close the Front Cover
15. The device will perform a few seconds of internal checks before it is ready for use again

Important:

• Fault may occur if you use toner other than the recommended type.


• When adding toner, do not turn off the operation switch. If you do, settings will be lost.


• Always add toner when the device instructs you.


• When a message "Add toner." is shown on the display panel, replace the toner.


• Store the toner bottles in a cool, dry place free from direct sunlight.


• Store on a flat surface.


• Do not repeatedly install and remove toner bottles. This will result in toner leakage.


• Do not shake the removed toner bottle. Remaining toner might scatter.

Remove the toner bottle carefully, pwr off and unplug the machine , then plug it in and turn it on do not put toner bottle into machine until asked for.

Plunger from the top of the previous bottle is probably still stuck in the machine. Remove the toner bottle and check/remove .

I suspect that it is the PCU causing the problem, and the message should clear once the PCU is installed and it (automatically) runs it's calibration cycle. Likely the toner auger gear has seized on the PCU, and broken. If the light does not go off after installing the PCU, then you may need a technician, as the toner motor may not be working, or there is a blockage within the toner hopper itself.....but again it is likely the PCU, especially if the toner bottle was empty when it needed replacement. Was it empty?? Did the machine work for a few days, or at least for a while? If so, it seems like too much of a coincidence that this problem would come up at this time.

Good Luck :)

Reinsert cartridge and restart it by unplugging or powering off
It should refresh the memory
Good Luck

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.

replace toner supply unit. inside of the unit are 4 mylars to push toner towards hopper exit gate. looks like them mylars are ripped off and the toner is not getting to the dev unit
