Any remaining tape will hinder ink output. • Did you install the ink tanks in their correct positions? 3. Execute cleaning Make sure that the printer is on and then click OK. Print head cleaning starts. 4. Complete cleaning Next, the message for nozzle check pattern printing is displayed. 5. Check the results To check whether the print quality has improved, click Print Check Pattern. To cancel the check process, click Cancel.
