Re: Replaced Toner- It Still Won't Work
It is possible that it is not installed correctly, ensure that it fits rightly on its place, oterhwise there is no way it would resume printing, reset the unit once again open and close the covers and turn the switch on and off to reset

I replaced the magenta toner with a Dell magenta toner and after about 50 copies the machine is displaying "004-321 Restart Printer". I've done this numerous times and the message won't go away nor can I print.
Hi, the chip on those toner bottles stores information about how much toner is left, so once that chip registers an empty toner bottle, it won't work even if you attach it to a new toner bottle. You'll need the chip from a new toner bottle, or one that hasn't registered no toner.
It means that there is Magenta toner density sensor error.Try to reset or replace Magenta development unit and then turn the printer off and back on.It should fix the problem,providing that the Magenta toner supply channel is not clogged up and functioning properly.
are you using a dell-branded toner cartridge? if yes, then you should replace the toner cartridge sensor and machine control unit (MCU). if no, you can enable the non-dell toner mode on your printer's operator panel. how? press menu, down until "configure" & press select; down until "maintenance" & press select; down until "non-dell toner" & press select; down until "on" & press select.
Have you already tried powering the printer off/on to see if this would clear the error? If so, are you using a Dell branded toner? If not, this could be why the printer has not recognized the replacement. It could be you recieved a bum toner cartidge, although this does not happen often, it can still happen. If you take your old toner cartridge and put it back in the printer, does it recognize it? If so, perhaps it is the toner cartridge.
If it is a bum Dell toner cartridge, Dell carries a seperate warranty on toner, apart from the warranty on the printer. Call Dell laser printer tech support. They will need your order number for the toner and have the cartridge handy as they will need an identification number off of the cartridge.
My message error was sepcific for magenta after I removed it to refill it. After refilling, cleaning metal contact points, resetting the metal tab which prevents message of "low toner", I put the cartridge back in and received the "magenta toner not installed" message. I turned off the printer (safety first!) , I then pushed the button left of the hole where you slide the cartridge in, There is a squarish hole with a circular or cynlinder shaped button in that squarish hole. Use a small screw driver to push and hold it in. While the button is held in I gently rotated the cartridges so that my magenta cartridge was no longer in view, (rotate them counter clockwise). I released the button, shut the door, then turned on the printer.
When you take the toner cartridge off the imaging unit, is there magenta toner in the open slot of the IU? Assuming that there is nothing wrong with the toner cartridge, you are possibly looking at a bad engine control board.
