Abstract
A media feed mechanism in a printer is provided. The media feed mechanism includes a drive roller for feeding a print medium in the printer, a pinch roller coupled to the drive roller for feeding the print media between the drive roller and the pinch roller, and a spring operatively connected to the pinch roller for biasing the pinch roller against the drive roller to exert a pinch force on the drive roller. Such a pinch force ensures that the print medium remains in contact with and is properly fed by the drive roller. The media feed mechanism further includes means connected to the spring for altering at least one character of the biasing force provided by the spring so as to alter the pinch force exerted on the drive roller.
