Have just bought HP Sprocket. I printed 6 photos and all of them have lines and streaks even though I put blue smart card for each print to try to calibrate and clean as per support information from HP. The lines and streaks are different in intensity for each photo. Aslo got a differnt tone of colour from the same picture. One is more brown than the other. Dose this mean it's a printer problem and I should return the product?
