Ink Is Not Ejected • Check 1: Has the ink run out? Check the Support Code on the LCD and take the appropriate action to resolve the error. Support Code List • Check 2: Is the orange tape or protective film remaining? Make sure that all of the protective film is peeled off and the Y-shape air hole is exposed, as illustrated in (A). If the orange tape is left as in (B), pull the orange tape and remove it. • Check 3: Are the print head nozzles clogged? Print the Nozzle Check Pattern to determine whether the ink ejects properly from the print head nozzles. Refer to When Printing Becomes Faint or Colors Are Incorrect for the Nozzle Check Pattern printing, Print Head Cleaning, and Print Head Deep Cleaning. • If the Nozzle Check Pattern is not printed correctly: Check to see if a particular color's ink tank is not empty. If the Nozzle Check Pattern is not printed correctly though ink is sufficient, perform the Print Head Cleaning and try printing the Nozzle Check Pattern again. • If the problem is not resolved after performing the Print Head Cleaning twice: Perform the Print Head Deep Cleaning. If the problem is not resolved after performing the Print Head Deep Cleaning, turn off the machine and perform another Print Head Deep Cleaning after 24 hours. When you turn the machine off, do not unplug it from the power supply. • If the problem is not resolved after performing the Print Head Deep Cleaning twice: If Print Head Deep Cleaning does not resolve the problem, the print head may be damaged. Contact the service center.
