Abstract:
1. A media sheet conveying apparatus to align a misaligned media sheet moving along a media feed path in an image forming device, comprising: a drive shaft extending along at least a section of the media feed path; and a first skew correction roller and a second skew correction roller spaced apart on the drive shaft and each positioned within the media feed path, the first and second skew correction rollers operative to each independently rotate about the drive shaft when the drive shaft is stationary; wherein the drive shaft when driven rotates the second skew correction roller a radial amount to align the media sheet prior to rotating the first skew correction roller, and wherein the first and second skew correction rollers each include a drive receiving surface, and the drive shaft includes engagement surfaces aligned with each drive receiving surface, the engagement surfaces adapted to rotate with the drive shaft and engage the drive receiving surfaces, thereby rotationally driving the first and second skew correction rollers.
