, how can I clear toner light in Sharp Mx D200

That is a miss reading of the toner density sensor. Which is located in the developer unit Replace the sensor or dv unit. Also check the connection of the unit to the copier and the harness from the sensor to the dv unit.

The toner light is in the shape of a triangle. If your light is in the shape of a circle you need a developer change. Technician required to do this.

it doesnt recognize the toner it needs oem not a refill

using third party toner or drum replace toner and drum with OEM

Btw, I’m available to help over the phone in case u need at https://www.6ya.com/expert/normanj_7893313f0751935f

F2 64 TONER SUPPLY ABNORMALITY ERROR (BLACK)

Have you tried replacing the Black Cartridge ?

#*C* and enter simulation 24 to clear counters

Problem with your toner supply .... you're not getting enough toner mixed into your developer tank. Sometimes the cartridge will empty out without the machine giving warning, or the CRUM counter chip on the back of the cartridge wil zap out or wind down to zero. Try replacing your toner cartridge, if that doesn't clear the code your developer mix is out of balance and may need to be changed and reset.

There is a problem with the Bk Toner supply.... check the End Seal was removed on the Cart, if not that, then call a Tech.

OR

put the an old, used bk toner cartridge back in and restarted the printer. Once all the codes cleared, removed the old bk toner and put back the original bk toner u had removed.

that should fix
