A print head is a crucial component of an inkjet printer that applies ink to paper. It contains tiny nozzles that spray microscopic droplets of ink in precise patterns to create images and text. The quality of the print head directly affects the clarity and detail of the printed output. Print heads can vary in design and technology, with some using thermal mechanisms to heat the ink, while others rely on piezoelectric crystals. Regular maintenance, such as cleaning the print head, is essential to ensure optimal performance and prevent clogs, which can lead to poor print quality.
