Set toner waste container

[TONERINMYNOSE]

After replaceing the drv and spc boards (we had to borrow them to repair another machine) the machine keeps displaying this message, we checked all connectors, and even replace the sensor for phone, i know its something dumb, any ideas?

Did you unplug the senor by the main motor (fly wheel area)

Check harness of toner waste container sensor.

[TONERINMYNOSE]

Are you refering to the blue 2 wire harness?

[mkb]

The one i have here is 3 white wire just below where the toner bottle tube. there is a senor arm and sensor there.

[TONERINMYNOSE]

Oh yea we checked and replaced that. No dice

[mkb]

have you done a firmware update?

Could the drv pwb be bad

[TONERINMYNOSE]

i check the connector on the drive pwb no 5vdc supply from pin, in F4 i get all ones in the test mode for that sensor (also includes exhaust fan 1 and 2 lock signal, the thing that kills me is the 2 boards came out of a working machine!!! how could we have blown one?? i gues anything is possible, i have been metering/staring at this damn thing for 4 hours now, cant seem to find a solution.

Sounds like you have a short somewhere. I had an 8045 with a "close left door" message. Replaced the drv, same thing. Turns out the wires on the front of the fuser were pinched and grounding to the frame. Three wire sets above the front of the fuser. Also, you might want to test other sensors on that board or in that cluster. Fuser exit sensor, inverter sensor, etc...
