I changed the cartridge for SXC 6345N Samsung printer. There is a message that says "Toner Sensor Error" what can I do to fix this problem?

If your printer is displaying "Toner Empty" error message even though the toner is full, there may be several reasons for this problem.

First, you may want to check if the toner cartridge is seated properly in its slot. Sometimes, the toner cartridge may not be fully seated, causing the printer to think that the toner is empty. Try removing the toner cartridge and then reinserting it, making sure that it is well-seated.

If reseating the toner cartridge doesn't resolve the issue, the next step would be to clean the printer's toner sensor. The toner sensor detects the presence of the toner cartridge and its level, and if it's dirty, it can cause the printer to display the "Toner Empty" error message even when the cartridge is full.

To clean the toner sensor, you will need a soft, dry cloth. Open the printer's front cover and locate the toner sensor. Gently wipe it clean with the cloth, making sure not to touch any other parts of the printer.

If these steps don't work, you may need to replace the toner sensor or the printer's firmware. In that case, it's best to contact the printer's manufacturer or a certified technician for further assistance.

Error: "Invalid Toner Cartridge"; Error: "Invalid Refill"; Message: "Change Cartridge"
Solution
One of these error messages may appear on the printer display immediately after or shortly after a new toner cartridge is installed into the printer. Note: This may not be specifically a toner cartridge problem; the error may be due to a stuck cover open switch on the printer.

To see if the cover open switch is the cause of this problem, open the top front cover and observe the message on the printer's display panel. The display should read Close Door or Insert Cartridge.


If this message is not displayed, the top cover open sensor and switch will need to be replaced. In addition, the printer may have damaged the new toner cartridge. If the cover open sensor is not operating properly, a new cartridge can be incorrectly flagged as a refilled cartridge by the printer. If this happens, the new cartridge will continue to cause an Invalid Refill or Invalid Cartridge error even if you try reinstalling it or installing it into another printer. If this should occur, please contact the point of purchase of the cartridge to find out how to get the cartridge replaced.

Caution: If the cover open sensor is not operating, do not install another new toner cartridge until you have completed the directions below. Inserting another new cartridge can cause that cartridge to stop working as well. Should this situation arise, please take the following actions:


Place the original working cartridge (the empty or near-empty one) back into the printer. This should clear the error message.

Turn the printer off. Doing this will disengage the cover open sensor.

With the printer switched off, open the top lid and remove the old toner cartridge.

Now replace the old cartridge with another new Lexmark toner cartridge.

Power the printer back on. The printer should now read this cartridge as a newly installed toner cartridge and the error should be cleared. The printer and toner cartridge should function properly now, but the top cover sensor on the printer will still need to be replaced.

If your printer is still under warranty or covered under a service contract, please contact Lexmark Technical Support or your service provider for further recommendations and instructions. Until you can get the cover open switch replaced, remember to have the printer powered off whenever you replace the toner cartridge.

If the top cover switch appears to be working fine, or if you have followed the above steps and your printer continues to post an Invalid Toner Cartridge or Invalid Refill error, make sure you are using a new original Lexmark toner cartridge. A toner cartridge remanufactured or refilled by a third party can cause this error.

To help identify a refilled cartridge, look for the yellow label attached to the toner drum and the body of the toner cartridge. If this is damaged or removed, the cartridge may have been refilled.

If you are using a third-party refilled or remanufactured toner cartridge, it is recommended that you install a new Lexmark brand toner cartridge. Lexmark cannot guarantee the compatibility of any third-party toner cartridges with our printers.

OR

1 Switch on the Lexmark X83 printer.

2 Lift open the cartridge door at the front of the device, below the scanner unit. The printer automatically moves the cartridge carrier to the correct position.

3 Pull each ink cartridge toward you to unclasp it from the carrier. Lift the cartridge out of the cartridge carrier.

4 Clean the copper contacts on the bottom of each cartridge with a clean, dry lint-free cloth. Use a gentle, circular motion to clean the contacts.

5 Insert the ink cartridges back into the cartridge carrier. Push back firmly on each cartridge until it snaps into place.

6 Repeat each step in this procedure again. Close the cartridge door.

The error message, which you have told me, not in the error message list. I think there is an internal failure for the printer. It is always recommend servicing your printer with authorized service centers. If the error message is not in the error list, owner cannot repair but, technician can repair the printer. I hope this information is useful for you. Thank you.

buy new cartridge

You need to replace the toner cartridge with a new one or a recharged toner cartridge that suits your model printer. Recharged or re-manufactured toner cartridges are cheaper than new ones.

most toners have a wing or *** or? that contacts a sensor in some way when the lid closes to tell the machine a toner is present. ive had these pieces broken off on new toner or the toner sensor may be disloged from its seat. check around the perimiter of the lid to find the sensor then see if anything is present to trip the sensor. if its broken off stick a q-tip in the sensor that will get you printing til you can replace the part
