  • Automatic media thickness compensator for a printer
    Patent number: 3990560
    Abstract: A carriage having a print head thereon is traversed along a platen to enable the print head to print along a line of printing in a serial-type printer. The print head moves with the carriage and is also mounted thereon for independent movement towards and away from the platen. A leaf spring biases the print head towards the platen, and a sensing shoe, secured to the print head, glides along media of various thickness mounted on the platen to maintain the print head (like a wire matrix) a predetermined distance from the media enabling the print head to print on various thicknesses of media automatically.
