How do I troubleshoot a Canon MP287 displaying error P10?

To troubleshoot P10, first, turn off and unplug the printer for 60 seconds. Then, carefully check for any visible paper jams in the paper tray, input area, and output area. Clear any jams you find. Next, inspect the paper guides to ensure they are properly adjusted to fit the paper size. If the problem persists, try replacing the paper with a fresh, compatible type. Finally, restart the printer and attempt to print again.
