Printhead Deep Cleaning 82
Routine Maintenance
Macintosh
1 Ensure that the printer is on.
2 Open the Page Setup dialog box.
The Page Setup dialog box can normally be opened by selecting Page
Setup... in the File menu.
3 Click the Utilities button to open the Printer Utility dialog box.
4 Select Cleaning from the pull-down menu, and then click the Deep
Cleaning icon.
5 Click OK.
Now the POWER lamp starts flashing and printhead deep cleaning begins. The process
takes one or two minutes to complete, so simply wait until the POWER lamp stops flashing.
After printhead deep cleaning finishes, print the nozzle check pattern to verify that the
printhead is clean. If the printhead is still not clean, repeat printhead deep cleaning and the
nozzle check pattern printing up to three times. If the problem persists, the printhead may
be worn out. Contact the Canon Customer Care Center.
