In an inkjet printer, the continuous inkjet state of the ink nozzles ensures print quality. Normal ejection of ink in the nozzle requires continuous application of pressure. The pressure detection component monitors and controls the pressure. High-precision, high-sensitivity pressure sensors control the accurate delivery of ink during printing.
