How can I prevent future occurrences of Canon printer error 5100?

To prevent future occurrences, always use high-quality paper and avoid overfilling the paper tray. Ensure proper shutdown procedures by using the printer's power button instead of just unplugging it. Regularly clean the printer's interior, carefully removing any dust or small debris. Avoid forcing paper through the printer, and promptly clear any minor paper jams. Performing recommended maintenance as per the printer's manual can also help prolong its lifespan and prevent such errors.
