Troubleshooting involves several steps. First, try a simple power cycle – turn the printer off, wait 30 seconds, and turn it back on. Next, check the memory card (if used) for damage and try a different one. If the problem persists, consult the printer's manual for specific troubleshooting steps or contact Canon support. A factory reset might also resolve the issue, but be aware this will erase custom settings.
