Brother 8840d tn540

Heyall, I was going to refill one of these for a friend, but I don't see how to reset the toner message. I've done it before for the tn350 & 430,s but this one is apparantly different. Before I put the toner in, does anyone know how to reset the message for this model?

like the tn350 you reset the flag so when you install it flips the switch and reset the machine and toner signal. if there is not flag on cart that means it is a starter cart and it does not have a gear.....
