  • Publication number: 20140232776
    Abstract: A method for controlling tension in a print media in a tension zone of a printing system comprises enabling an active tension control mode until the tension in the print media is in a stable state for a given period of time, and then switching to a synchronized control mode. The tension is monitored to determine if it exceeds a tension inner band but does not exceed a tension outer band while in the synchronized control mode. The speed of drive rollers is adjusted in response to this determination. The tension is also monitored to determine if it exceeds the tension outer band while in the synchronized control mode. The synchronized control mode is disabled in response to this determination and the active tension control mode is enabled. The frequency of speed adjustments is lesser in the synchronized control mode than in the active tension control mode.
