Hello Sir,
More exactly what is your error? F2-02 or F2-04?
For F2-04 try to change toner cartridge or verify if the chip on the toner cartridge is correct positioned.
For F2-02 you must verify if toner sensor is not dirt, the toner sensor is positioned on back of developer unit, clean very well.
Best Regards,

Hello
If you open the side cover on the right side of the machine then you will be able to open the front cover.The toner cartridge wil have a green lever if it is not broken off.lift the green lever gently.pull the lever to your side.(Out of the machine to the front). the toner botle is inside this cartridge.Now you wil be able to take it out.Make sure the top of the cartridge come out with the botle.If not it wil stil be in the cartridge. replace the toner botle in the cartridge and push it back in to the machine and push down the green lever,close the front door and the the side door.your machine should load toner to the pcu now.Good luck

you can change. You have a door right in front of the equipment. If you open that door you see the toner bottles. You pull the old one and then put the new bottle

Change the used toner botle,desasembly the LCT tray,open the front cover and change the waste toner bottle.
