black toner supply trouble, try a different toner cart, remember to shake the cart before installing. power the machine on and off, if the code is gone then it was the cart if it doesnt clear your service tech needs to see the machine.

Loss of Black toner supply or arching of black drum unit.
I agree with Nachoman. try another cartridge. Check the sealing tape has been fully removed from the cartridge as well as the green colored plug. I have seen many cases where the seal tape has been left on, cartridge installed, then F2-40 shows not long after.
Also, if you have an original drum unit frame, change the frame with the new Modified version to prevent arching at the rear cover of the drum unit against the inside back plate of the machine.
Check that the black dev tank is not low or empty, re-position both drum & dev tank.

thank’s very much tomorrow i’ll try it
