How can I get the compatible toner in my c5100 to work? It keeps reading m sensor error.

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.

Hi there
I have found various documents which may help you with this problem and possible future problems. This page:
Error Codes Kyocera Mita KM1530 Code C710
can find any code connected with Kyocera mita machines by changing the machine and the error code in the appropriate drop down menus. C710 is identified as:
Description Toner sensor problem
• The sensor output voltage is outside the range of 0.5 to 4.5 V during toner control.
• The toner sensor control voltage cannot be set within the setting range when maintenance item U130 is run. Causes Defective toner sensor. Poor contact of the toner sensor connector terminals. Developer problem.
Another page showing error codes and their meanings is here;
Kyocera Mita Error Code Messages
and this confirms the above.
Also the link below takes you to a Kyocera web page where you can download various manuals for this machine (KM-1530). By changing the product in the drop down menu to KN-2030 you can get similar manuals for this machine.

In your question you mention "Compatible KP23153 Black Toner Cartridge 106153" and that led me to wonder if the compatible cartridge is the cause of your C710 error since that is toner related.
Might be worth trying an original cartridge to see if the error goes away.
Hope this is helpful, if so would you please register that with Fixya
Cheers

The first thing i can tell you is that is weird!!!!
Because if you change the developer that error should disappear. It could appear later but not in the moment because the developer already have toner and the TD sensor will read it.
And that's the question: When you said "replace developer" you mean just the developer or the DEVELOPER UNIT??? Is your TD sensor working good????

This error is an "Incompatible toner" error for using non-original Oki toner. The problem is the chip sensor cannot read the chip on the toner. So either the sensor is not working or the toner is defective.
Regards Abhilash How do u rate the service?

do a google for it from the manufactures website ...

The toner detection sensor in the toner hopper is either fouled or defective. This is why that no matter what you've done thusfar, it's still saying it needs new toner. Not an easy repair. Recommend a certified Toshiba tech to do the work.

Drum units are different than toner. Drums are expensive but need to be replaced between 30,000-40,000 impresions

An error has been detected in your printer's Control Panel. You should restart the printer, and if the same problem reoccurs, you will need to have the printer serviced. Problem seems to be pointing to the cyan toner sensor

Fatal Error 161-Toner Sensor Error, Color:Magenta

Fatal Error 163-Toner Sensor Error, Color:Black

Both are Sensor errors....You would first check the lock levers that hold the toner cartridges in, if everything is fine with them then you could possible have toner dust on the sensors. First take out the cartridge that you are having problems with, then use a dust off can and carefully clean out any axcess toner that you can see where the toner sits. there is a sensor that looks like a clear plastic or glass eye that reads the cartridges and it sometimes gets dirty.
