ABSTRACT:
Systems and methods for reducing sheet skew in a document processing device are disclosed. A document processing device may include a plurality of nips, a sheet skew measurement system, a feedback controller and an actuator. Each nip may include an idler wheel and a drive wheel. The sheet skew measurement system may be configured to measure sheet skew for a sheet. The feedback controller may be configured to generate a control signal in response to the sheet skew measured by the sheet skew measurement system. The actuator may be configured to adjust a loading force applied to a sheet by an idler wheel for at least one nip in response to the control signal.
