Abstract: A magnetoelectric apparatus for measuring the droplet frequency response at a printhead by applying a method comprising a metallic detecting plate and a magnetic ring, and a method using the foregoing apparatus to determine the maximum droplet frequency response of the printhead. When an ink drop jetted from the nozzle makes contact with the detecting plate, which is perpendicular to the nozzle plate of the printhead, a current flows through the detecting plate immediately, and is detected as a portion of an expected signal. As soon as the ink drop leaves the nozzle completely, the foregoing current no longer exists. However, the magnetic ring generates an induced current that flows in the same direction as that of the foregoing current to complement the absence thereof, wherein the induced current is also detected as another portion of the expected signal. The expected signal is then processed by a signal-processing routine for determining the maximum droplet frequency response of the inkjet printhead.

Abstract: The present invention is an ink pressure adjustment device of inkjet pen; the device is utilized to adjust negative pressure in an ink cartridge mainly through an expandable and shrinkable gasbag installed in the ink cartridge, and a tension valve attached on the surface of the gasbag. The tension valve can open or close automatically an air hole that communicates atmosphere and the inner part of ink cartridge via the gasbag according to the expansion and shrinkage of the gasbag, causing a part of atmosphere to enter the ink cartridge so as to adjust the negative pressure of the ink cartridge and not only can prevent ink from leaking but also prevent the negative pressure from being too large to fail the inkjet printing.
