If your printer isn't working after a power outage, there are a few things you can try:

1. Check the power and cables: Make sure the power cord is securely connected to both the printer and power source. Check any USB cables as well.
2. Turn off the power: Disconnect the power cord from the printer and wall socket. Wait for a few moments before plugging the printer back in.
3. Change printer settings: Reset any settings or configurations that may have changed, such as default paper size or type, print menu settings or formatting options.
4. Check the cartridges: Check that the ink cartridges are seated and in good condition.
5. Restart your computer: Turn off the computer and turn it back on.
6. Install updates: Install any available updates for your printer or your computer's operating system.
