hi you need to replace the toner cartage.

Kyocera 2050 add toner error problem

Check your old toner bottle and make sure the plastic "cap" is still in the bottle. These machines have an occaisional problem with the caps coming off (not the black screw off cap but the semi clear cap under the black screw off cap) and staying inside the black plastic "cup" that you insert the toner into. If the cap is missing it may be stuck inside this cup. If the cap is still in your old cartridge then try opening/closing the front door and letting the machine cycle to see if the toner light goes out. May have to do this several times. Had one customer just yesrday have to do this to clear the toner light after adding toner.
Good Luck.

OK CAREFULLY take out the toner bottle, then open close the front door, then power off the machine, wait 10 sec, then power the machine up with the toner bottle out, only add the bottle when it ask for toner

F26-1 at power up. [Description] F26-1 at power up.
[Solution]
PROBABLE CAUSES:
1. The TDS (Toner Density Sensor), in the developing unit, has detected a depletion of toner.
Note: This may have been caused by the customer making an excessive amount of copies while the machine was out of toner. It may also be caused by a bound toner addition system.
Clean all toner from the toner recycle and toner supply assemblies. Confirm that the gear mesh between the toner supply auger drive gear and toner supply motor (M4) is flush. If toner supply conveyance is normal and the toner cavity is empty, install a new toner cartridge (Item #950236) and then perform the following diagnostic mode to replenish the developing unit with toner:
a. Access the 47 mode (power the copier ON while pressing the 4 and 7 keys).
b. Enter output code 54.
c. Press the START button.
Note: Toner will now be added to the developing unit and stop automatically when target level is reached, although it will not run any longer than 3 minutes.
d. Power copier OFF/ON to return to normal copy mode.
Note: Perform the following 25 mode software switch settings to minimize the amount of copies that can be made, prior to copy inhibit, when the ADD TONER message is displayed:
- Access the 25 mode (hold down the 2 and 5 keys at power ON).
- Select [1] (SOFTWARE SW).
- Using the up and down arrows, scroll to the following software switches and set them as follows:
a. 4-0 set to 0
b. 4-1 set to 0
c. 4-2 set to 0
d. 4-3 set to 0
- Power OFF/ON to return to normal copy mode.
Notes:
A. These setting will allow the ADD TONER message to be displayed immediately and only allow 100 copies to be thereafter.
B. Copier inhibit will automatically be released when a new toner cartridge is installed.

2. The toner conveyance gear is worn. The toner conveyance gear is driven by the toner supply motor located on the toner supply unit.
Replace the toner conveyance gear (p/n 26NA32680).

Take out the toner and clean all contacts that you see. and make sure that it is seated properly. if the contacts are not touching it will not see the cartriage.

Try turning your copier off & back on. Allow the machine to cycle after turning it back on - until it comes to ready or displays add toner signal again. You can try this three or four times as it sometimes takes the machine a few trys to advance the new toner to the toner sensor. If after 4 attempts you are still getting the add toner message - you may have a dirty or faulty toner sensor. The toner sensor is located inside the developing unit that you are loading toner into. Toner sensor is usually located on the bottom of the developing assembly & is held in by 2 scews. It can be cleaned with a dry cotton rag & reinstalled. 90% of the time power cycling the copier a few times will solve this problem.
