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. 1 Make sure that the printer is on. 2 Open the printer properties dialog box. Refer to "Opening the Printer Properties Dialog Box Directly from the Start Menu" in "Opening the Printer Properties Dialog Box (Windows)" of the User's Guide on-screen manual. 3 Start Print Head Deep Cleaning. (1) Click the Maintenance tab. (2) Click Deep Cleaning. (3) Confirm the displayed message and click Execute. Note Clicking Initial Check Items displays the items to be checked before deep cleaning. (3) (4) 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 one to two minutes. 4 Check the condition of the Print Head. (1) Load a sheet of A4 or Letter-sized plain paper in the Auto Sheet Feeder and set the Paper Thickness Lever to the left. For details on the Paper Thickness Lever, refer to "Front View" in "Main Components" of the User's Guide on-screen manual. (2) Print the nozzle check pattern to check the print head condition. See "Printing the Nozzle Check Pattern" on page 15. (3) If the print head nozzles are still not clean, perform Print Head Deep Cleaning again. (4) If this does not solve the problem, a FINE Cartridge may have run out of ink. Replace it with a new one. See "Replacing a FINE Cartridge" on page 26. 1 Make sure that the printer is on. 2 Open the Canon IJ Printer Utility dialog box. Refer to "Opening the Canon IJ Printer Utility (Macintosh)" in the User's Guide on-screen manual. Routine Maintenance 21
