Abstract:
1. An apparatus to clean a nozzle plate of an inkjet head, comprising: a wiper blade; a setscrew coupled to the wiper blade; a mounting body having a top portion and a bottom portion, the top portion being closer to the wiper blade than the bottom portion; a spring disposed between the wiper blade and the bottom portion of the mounting body, wherein a portion of the spring is coupled to the wiper blade; a moveable member disposed in the body, wherein the moveable member includes a threaded interior wall for receiving the setscrew, and threading the setscrew to the threaded interior wall adjusts a compression load of the spring; a cavity in the mounting body; and a fluid port coupled to the cavity; wherein the compression of the spring varies, thereby varying a distance between the wiper blade and the bottom portion of the mounting body, as the wiper blade is transported across a face of the nozzle plate to clean the nozzle plate, and wherein a fluid supplied through the fluid port urges the moveable member and the wiper blade toward the nozzle plate.
