Click Nozzle Check Before printing the nozzle check pattern, check the following items: Check that the printer power is on. Then open the Ink Tank Cover. Check the following items for each ink. Then, if necessary, perform Nozzle Check. • Is there ink remaining in the tank? • Is the ink tank attached properly? If the Ink Lamp is not lit, remove it and attach it again. • Did you install the ink tanks in their correct positions? 3. Print a nozzle check pattern Click Yes. Printing of the nozzle check pattern begins. 4. Check the print result Check the print result. (A) As long as the horizontal lines are in line, and not missing, the nozzle is working normally.
