Factory Resets
The menu of a canon printer provides access to the factory reset option. Using this option you will return all the settings to factory stipulations and can require reconnecting to your own network and moving through the complete setup process again.
Ink Cartridge Resets
When you fit a new ink cartridge, the canon printer will guide you through the cartridge realignment procedure before permitting you to move forward with the new print jobs. Perform the menu prompts for realignment and to print a sample sheet of paper. Refilled ink cartridges make a reset issue for Canon printers, and there are numerous ways to fix the printer through the problem. For printers of the version Pixma MP/MX/MG, ink cartridge resets ask you to reset the printer as per the BCH technology.
I hope this helps!
