That model uses a TD cartridge so when you replace the toner the developer is included. The crum chip on the TD cartridge will reset the counters and sets the developer.

the best you can do is to replace the toner cartridge itself. It won't work if you just refill it.

That unit uses an AR-016TD Toner/Developer Cartridge. The developer is changed each time you replace the toner. To remove the drum unit open the right side cover, then the front cover, remove the TD cartridge, loosen the green screw on the front of the developer unit housing just above the TD slot. carefully remove the DV unit without tipping or you will spill out the existing DV. Then you can pull out the drum unit. There may be a green screw on the drum that must be loosened but I don't think so on that particular model. Installation is the reverse of removal.
