I have a kyocera KM-1820 and its toner is nearing replacement. so my questions are as follows: 1) does anyone know if using replacement toners is just okay? original toners costs a lot. 2) if using replacement toners are okay, what brand can you suggest i should go for? thanks a lot for your reply to this query.

If your Kyocera KM 3050 printer is displaying "toner empty" message, even though you have replaced the toner cartridge with a new one, it's possible that the toner sensor inside the printer is malfunctioning or is dirty. You can try the following steps to fix the problem:

1. Open the front cover of the printer and remove the toner cartridge.

2. Look inside the printer, and you should see a small sensor that detects the toner level. This sensor may be dirty or covered with toner particles.

3. Clean the sensor with a soft, dry cloth and reinsert the toner cartridge into the printer.

4. Close the front cover and power on the printer.

If the problem persists, try resetting the printer's toner counter. Here is how to do it:

1. Press the "System Menu" button on your printer.

2. Scroll down to "Service" and press the "Enter" button.

3. Scroll down to "Maintenance" and press the "Enter" button.

4. Scroll down to "Reset Toner Counter" and select it.

5. Restart the printer and check if the problem has been resolved.

If none of these steps work, there might be a more serious hardware issue with your printer's toner sensor, and it's advisable to contact a Kyocera printer support expert or service center for assistance.

C7990 is

Waste toner reservoir overflow problem (when the total number of copies is 100 thousand sheets or more)

• After E31 is displayed, 1,000 sheets are copied. Or waste toner exceeds 5 g.

Defective waste toner sensor or engine board (KP-5061).

Shake the process unit from side to side and turn the power switch off and then on. If the problem cannot be solved, replace the process unit. After replacing the process unit, turn the power switch off and then on. If the problem

cannot be solved, replace the waste toner sensor or the engine board (KP-5061).

I hope this is helpful,

You need to replace the procces unit. The waste toner can not be emptyed the unit needs to be replaced, Some times if you remove the proccess unit and gentally shake it left to right several times and place the unit back in the copier the error will clear, if not you will need to replace the process unit which is a PU-102.

This is going to be messy, so do it outdoors.

Remove the entire drum unit. Remove toner cart

Remove the chrome screw on the right side and the cap.

You can empty the waste chamber on the image unit by removing the screw from both ends of the unit, pull the ends off and empty it out. It's a messy job so have a good plastic bag and a toner vacuum if possible. The message might stay on awhile but will disappear with time. The alternative is a new image unit.$$$$$$

TO empty the waste toner on a KM/CS 1820 you have to remove one of the side covers from the drum unit on the machine and vac out the old toner i've had customers try to reuse the toner please do not do this. just vac it out good and your normaly good to go!!

Open the front cover and locate the waste toner bottle. Empty it out and see if that corrects the problem. If that doesn't work, clean the bottle after emptying it. If the doesn't work, replace the waste toner bottle with a new one.
