How can I perform a print head cleaning on my Canon Pixma MX922?

You can initiate a print head cleaning through the printer's control panel or the Canon IJ Printer Utility on your computer. Navigate to the 'Maintenance' or 'Utility' section, then select 'Head Cleaning.' Run the cleaning process once or twice, but avoid excessive cleaning as it consumes ink. After cleaning, print a test page to check print quality.
