DC250 toner supply motor running continuos

[ScoTTeL]

Check atc sensor on magenra developer housing.

I have a DC250 that is not printing yellow. The yellow toner under the slider door is packed and the other colors are not. I know this is probably a sensor. Which one, where is it located and where can I purchase one?

Thanks guys!

Probably the auger for toner transport is broken.
You must check the toner flow path. I dont think it's a semsor.
It's a good ideea to purchase a service manual for machine before disassembly it.
