samsung c8380nd waste toner

[lightningjeremy]

has anyone had any problems with false waste toner readings? i replaced the waste toner hopper(which was like a need in a hay stack trying to find one) and a day later the machine is saying the hopper is full again. i cleaned the sensor and the next day the message comes back. what am i missing? thanx

They have modified the waste toner tank and also a pcb for this fault.
Contact Samsung and they should supply you the mod kit.
