Hello thanks for using Fixya

A 929 Service Toner Sensor error indicates a problem with the toner sensor, the front harness cable, or the developer drive. It could also mean that the toner cartridge is defective.

The most likely cause of this error is the toner cartridge itself. This is especially true if it is a new cartridge and the error started after you installed it.
To solve it try this:

Take the cartridge out of the printer and locate the encoder wheel on the right-hand side of the cartridge. The encoder wheel can be found on the right side of the cartridge (usually over a bar code sticker). It is a thin, black, plastic wheel with small rectangular notches cut into it. This wheel will sometimes get stuck, but you can free it by turning it by hand.
Try moving the wheel forwards and backwards a little. If it does not turn correctly, you will receive a 929 Toner Sensor error on the printer when you try to use the cartridge it is attached to
Note: The encoder wheel moves only a little bit each way. It should not make a complete revolution. If it does, the wheel is probably broken.
Try to move it a little bit each way a couple of times to see if you can free it up. Caution! DO NOT force the wheel as you could break it.
If the wheel on the toner cartridge is stuck, try another new toner cartridge. ( If you do not have another new toner cartridge available, an old toner cartridge or another cartridge from a working printer of the same model will also suffice for this test.)
Power the printer off and install the second toner cartridge. Then power the printer back on. If another toner cartridge clears up the 929 error, the printer is fine and the problem is with the toner cartridge.
If the error does not clear, there may be a problem with the printer.
If you narrow down the problem to the toner cartridge, call the point of purchase and explain the situation to them. They may have a replacement policy.
If you receive this error with a second toner cartridge, you may want to check if the Front Harness Cable is plugged into the Toner Sensor then Do the following:

Turn off the printer and remove the toner cartridge.
Look inside the printer at the place where the cartridge goes (on the right). You should see the Toner Sensor. On the back of the sensor assembly, you should be able to see a white cable connector.
Push this white cable connector into the toner sensor assembly by pushing the connector towards the front of the printer.
If you continue to receive the 929 error the final option is your printer will probably need service.

I have a C3530 MFP and it won't print because it says check toner cartridge black. Toner Sensor Error


Hi

Thanks for using FixYa. Toner sensor error is related to the agitator inside the toner cartridge, it occasionally falls out of its housing so it does not move the toner sensor which is the white plastic piece that moves up and down on the coloured handle, the toner sensors themselves see this white flag if it doesn’t move then the printer thinks the sensor is broken so toner sensor error is flagged and if the flag moves too quickly the machine thinks the toner is empty. To resolve the issue your printer is facing with please check that toner lock lever is in position and follow the following procedure---

Press the cover release and open the printer’s top cover fully. Make sure the Toner Cartridge in question is correctly positioned and the right hand clip is pushed back. While holding it by its top centre, lift the image drum, complete with its toner cartridge, up and out of the printer. On the Right hand side of the toner look for a sensor patch, make sure this is not dirty. If it is dirty clean it with a soft object such as cotton wool. Now look inside the printer opposite to where the sensor patch would sit. There is a black square with a sensor located inside and check that this is not dirty. Now replace the drum and toner, and close the printer cover. Try to print a test page and it will start printing normally.

Please do accept the solution if the issue is resolved or else revert for further assistance.


Thanks

540 : y toner sensor error


Hi moneybaggz52:
Here is your problem.
Symptom:
When setting up a brand new C5100n or C5300n out of box, a toner sensor error is encountered.

The printer can display any one of the following errors:

543K: TONER SENSOR ERROR

540Y: TONER SENSOR ERROR

541M: TONER SENSOR ERROR

542C: TONER SENSOR ERROR
Cause:
This generally can be caused by two things.

1. The toner cartridge lock lever is not in the correct position.

2. The Transfer Belt lock levers are not in the correct position.
Resolution:

Check the appropriate toner cartridge lock lever (Shown below) and make sure that it is in the correct position.
0.110?openelement&fieldelemformat=gif 2.1ac?openelement&fieldelemformat=gif
CORRECT POSTITION INCORRECT POSITION


Check both transfer belt lock levers (Shown below) to ensure that they are in the correct position.
5.2eea?openelement&fieldelemformat=gif
CORRECT POSITION

543k toner sensor error


Your indication regarding the 100% does not necessarily indicate a damaged chip (sensor).
Many chips do not work by actually sensing the toner but by usage or other tricks.
We cannot be sure about what happened but replacing the drum and affected items
should solve the problem. Needed parts may be found at
