Ink jet printer with advanced wiper and cleaner system
The patent US12011929B2 describes an innovative ink jet printer designed to enhance the efficiency of ink discharge and maintenance. Central to its design is an ink head equipped with multiple nozzles for discharging ink onto a recording medium. The printer features a movable carriage that supports the ink head and a wiper that extends upward to clean the nozzle surface. A wiper mover facilitates the wiper's movement in a sub-scanning direction, while a wiper cleaner is strategically positioned to contact the wiper and remove any ink residue. The controller of the printer is programmed to ensure that the wiper effectively wipes the nozzle surface after making contact with the wiper cleaner, which is designed to absorb more ink than the wiper itself.
Further claims detail the construction and functionality of the wiper cleaner, which may include a continuous foaming structure made from polyolefin resin, and is designed to be harder than the wiper. The wiper cleaner's dimensions are specified to be longer than the wiper, and its lower end may feature an arc shape or a tilt towards the wiper for optimal contact. The controller is also programmed to adjust the wiper's velocity during contact with the wiper cleaner, ensuring effective cleaning. Additionally, the patent encompasses configurations for printers that utilize photocurable ink, incorporating a light emitter and a light shield plate to prevent interference during the printing process. Overall, the patent outlines a comprehensive system aimed at improving the operational efficiency and maintenance of ink jet printers.
