Print Head Deep Cleaning If print quality does not improve by standard Print Head Cleaning, try Print Head Deep Cleaning, which is a more powerful process. Note that cleaning the Print Head causes used ink to be absorbed in the ink absorber. Print Head Deep Cleaning consumes more ink than standard Print Head Cleaning, so perform this procedure only when necessary. Note Make sure that the Inner Cover is closed. 1 Make sure that the printer is on. 2 Press the Open button to open the Paper Output Tray and extend the Output Tray Extension. 3 Open the printer properties dialog box. 4 Start Print Head Deep Cleaning. (1) Click the Maintenance tab. (2) Click Deep Cleaning. (3) Select the ink group to be deeply cleaned. When cleaning the nozzles of black ink tanks: Select Black to clean the nozzles of PGI-5BK, Color to clean the nozzles of CLI-8BK. (4) Click Execute. (3) (4) (5) Confirm the displayed message and click OK. Print Head Deep Cleaning starts when the POWER lamp starts flashing green. Do not perform any other operations until Print Head Deep Cleaning finishes. This takes about 90 seconds. Note Clicking Initial Check Items displays the items to be checked before deep cleaning. 5 Check the condition of the Print Head. (1) Load a sheet of A4 or Letter-sized plain paper in the Rear Tray or Cassette. (2) Press the Paper Feed Switch to select the paper source in which you loaded the paper.
