Try this one, Turn on the printer, Take out the inks, remove the printhead, put back the printhead make sure it will snap and you hear a click, put the inks back, wait for the printer to initialize, Press the Menu button, look for Calibrate printer, then print calibration page, then scan it after. Load a regular paper. Then try to print a demo page by pressing Photo and Copy at the same for 5 seconds then let it go. If same problem persist call this no for further assistance 1800 421 6699
