  • Line printer having a motorized platen that automatically adjusts to accommodate print forms of varying thickness
    Patent number: 7290949
    Abstract: Methods for setting the print gap in a printer are disclosed. The printer has an eccentric platen wherein rotation of the platen changes the print gap distance. A driver controls the eccentric platen rotation, and a sensor may be used to determine the position of the motor and platen. The configuration of an eccentric platen and a driver having a position sensor enables measuring the thickness of a form at one or more locations to create a representative thickness profile of the form, which may be saved to the printer's computer memory and repeated when printing similar forms in the future, thus obviating the need to measure the thickness of every individual form.
