Why is my Canon G3000 printer printing blank pages, and how can I fix it?

Printing blank pages can be caused by several issues: empty ink tanks, a clogged print head, or incorrect printer driver settings. Check the ink levels first. If they're sufficient, perform a print head cleaning and nozzle check. Ensure the correct printer driver is selected and that the 'grayscale' or 'black and white' printing option is not accidentally enabled. If these don't work, the print head may be damaged.
