How often should I replace the ink cartridge in my Canon Pixma G2020?

The replacement frequency for a Canon Pixma G2020 ink cartridge depends on the ink type and usage. Generally, the cartridges are designed for a specific number of pages (typically 500 pages). Monitor the ink levels regularly using the printer's display and replace the cartridge when it reaches the low ink warning. Consider using high-yield cartridges to extend the lifespan of the cartridge.
