Patent ID: 8494430

Claim:
An apparatus for de-skewing substrate media in a printing system, comprising: at least two sensors for measuring skew of the substrate media being transferred relative to a process direction; and a nip assembly for moving the substrate media in the process direction, the at least two sensors being disposed ahead of the nip assembly in the process direction, the nip assembly including a nip having a drive roller and an idler roller for engaging the substrate media, a controller causing the nip assembly to pivot from a default position an amount responsive to the skew measured by the at least two sensors, the controller causing the drive roller to stop rotating prior to the substrate media engaging the nip to permit a leading edge of the substrate media to engage the stopped drive roller, the controller causing the driver roller to pull the substrate media through the nip, and the controller causing the nip assembly to pivot to the default position while the substrate media is controlled by the nip in order to de-skew the substrate media.
