My printer is displaying a 'Replace Printhead' error. What should I do?

A 'Replace Printhead' error indicates that the printhead, which is responsible for depositing ink onto the paper, is faulty or nearing the end of its lifespan. The printhead is often integrated with the ink cartridge. You'll likely need to replace the entire ink cartridge/printhead unit. Consult your printer's manual for specific instructions on how to replace the printhead. Be aware that printhead replacements can be costly.
