Hi,

If the main problem is just the toner light on then what you could do after installing the new toner is resetting the printer. You could do that by powering the printer off, open the front cover (as if you were to replace the toner) with the front cover open and the printer off push and hold the two buttons on the printer and turn the printer on while holding down the buttons then once the bottom light stays on solid, release the two buttons and that should reset the printer.
Now if the toner light is blinking that means that you have reached the 30,000 page mark and the Photoconductor needs to be replaced. If that is not the case you can follow this link to a procedure where it will explain how to reset the Photoconductor. http://bit.ly/91SWS3
