Ensure the printer is powered off and unplugged. Open the ink cartridge access door and look for any lodged paper, especially near the carriage. Also, check the paper output tray and the area where paper is fed into the printer. Use a flashlight to thoroughly inspect the inside for small debris or torn pieces of paper that might be difficult to see. Avoid using sharp objects that could damage internal components.
