Re: mp c3500 not adding toner black

If the customer just changed the toner cartridge, and it will not fill up, and just ask for more toner, then it's the pump. If not, then check if the rubber tube from the toner hopper, to the toner pump is clogged. I use pliers to pinch the tube all the way, to crush the blocking toner lumps, then pressured air on a can to blow it clean. Use an empty paper box or something to blow the toner into, as it will make a mess. Or just replace the tube.

1) Dev drive gears.2) Pump3) Blocked pipes4) The dev drive gears behind the dev unit on the frame of the machine5) Dev clutch6) Dodgy toner cartidge (if it's a compat)

thanks, my buddy us handling the issue as it is becoming personal to him. I will update this mystery as all of the above have apparently been tested and in working order. There is a TIB about it referring to corrupt nvram or old firmware.

Maybe Development Unit...or Drive Unit.

Everything mechanical works - toner bottle rotates, pumps are working (swapped them, they are identical) but for some reason toner gets depleted. I read somewhere nvram is corrupted. Any clues?
