Tips

Before replacing the print head, clean the platen roller and print head area with isopropyl alcohol to remove adhesive residue and dust. Always power off and unplug the printer before installation. Handle the new print head by its edges to avoid static damage. After installation, run a test print and adjust print density settings if necessary. Keep the old print head as a spare for emergency troubleshooting.
