Are there any specific Canon G3000 maintenance procedures that can prevent error 5200?

Regularly performing basic maintenance like 'Nozzle Check' and 'Head Cleaning' from the printer's utility software can help optimize ink usage, but these procedures also contribute to the waste ink. There isn't a specific user-level maintenance to empty the ink absorber. The best prevention is to be aware of your printing habits and consider professional servicing when the printer indicates it.
