My printer is printing gibberish or random characters. What should I do?

1. Check the printer's settings, including paper size, tray configuration, and scaling.
2. Make sure that the paper is not stuck, jammed, or misaligned in the paper tray.
3. Clean any dust or debris from the paper tray and check if it is properly installed.
4. Make sure the printer driver is updated.
5. Perform a power cycle on your printer.
6. Reset the printer to factory default settings if none of the above steps help.
