Suggest to never purchase the machine of this company specially in NCR. We have purchased 3 machines against commitment of by back of old machine of same company, which was troubling since first day.
But after past of almost 3 years, they are not fulfilling the commitment.
Service and availablavai of spare parts is also very poor.
No one can listen your problem after selling the machine. Be careful
