An endless ink ribbon cartridge with protected splice of the endless ribbon, wherein a reactance detector element housed in the cartridge at a location close to a predetermined travel path of the ink ribbon increases its reactance as a conductive strip disposed on the ribbon at a predetermined location relative to the splice moves close past the detector element, the reactance increase being detected by a protection arrangement external of the cartridge to prevent printing operations from being carried out through said splice.
