1. A skew detection device to determine a skew of a print media in a media path, the device comprising:
a first contact roller rotatable around a first axis;
a second contact roller rotatable around a second axis;
a first sensor to measure a first rotation parameter of the first contact roller; and
a second sensor to measure a second rotation parameter of the second contact roller,
wherein a movement of the print media over the device rotates the first contact roller and second contact roller, and wherein the first sensor and the second sensor are in communication with a controller to determine the skew of the print media based on the first rotation parameter and the second rotation parameter.
