Replacing the ink cartridge in your Canon printer is a straightforward process. First, ensure that the printer is turned on and the paper tray is empty. Open the printer cover and locate the cartridge carriage. Wait for it to move to the center. Gently press the empty cartridge, releasing it from the carriage. Take the new ink cartridge out of its packaging and remove the protective tape. Insert the new cartridge into the corresponding slot, pushing it firmly until it clicks into place. Close the printer cover, and the printer will automatically recognize the new cartridge. Now you’re ready to resume printing with fresh ink.
