Turn off the printer and open the top cover. Remove any jammed paper gently. Check for torn pieces inside the paper path. Use tweezers if needed. Close the cover and power on. Run a test print to confirm.
How do I clean the print head?
After the printer has cooled down, open the cover and lower the print head. Use a cotton swab dipped in isopropyl alcohol to gently wipe the print head surface. Allow it to dry completely before using.
