Abstract
Systems and methods related to adaptive ribbon speed control for a line matrix impact printer are provided. A ribbon cartridge includes a ribbon configured to be driven at a ribbon speed, and a ribbon gear configured to rotate with movement of the ribbon. The ribbon includes a ribbon joint patch detectable via a first sensor to determine a first ribbon speed of the ribbon. Rotation of the ribbon gear is detectable via a second sensor to determine a second ribbon speed of the ribbon. A target ribbon speed is determined based on at least one print job characteristic. A current ribbon speed is determined based on the first ribbon speed and the second ribbon speed. The ribbon speed is adjusted based on a difference between the current ribbon speed and the target ribbon speed. Associated systems and methods are also provided.
