Cleaning the Print Heads The print head cleaning function allows you to clear up clogged print head nozzle. Perform print head cleaning if printing is faint or a specific color fails to print, even though there is enough ink. Cleaning 1. Select Utilities from Remote UI 2. Click Cleaning Before running the cleaning, check the following items: Check whether the printer is on and open the printer's cover. Check the following items for each ink. Then, if necessary, perform Cleaning. • Is there ink remaining in the tank? • Did you push in the ink tank completely until you heard a clicking sound? • If the orange tape is there, has it been peeled off completely? 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 Yes. 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 Yes. To cancel the check process, click No. If cleaning the head once does not resolve the print head problem, clean it once more. Important • Cleaning consumes a small amount of ink.

Perform deep cleaning when two Cleaning attempts do not resolve the print head problem. 1. Select Utilities from Remote UI 2. Click Deep cleaning 121
