Abstract
Methods and system for reducing sheet skew in a sheet transport system are disclosed. A sheet transport system may include an idler wheel, a drive wheel a drive motor and an actuator. The idler wheel may have a substantially rigid outer layer. The drive wheel may have a compliant outer layer and may correspond to the idler wheel. The drive motor may be operably connected to the drive wheel and may be configured to cause the drive wheel to rotate around a shaft. The actuator may be operably connected to the drive wheel and configured to cause the drive wheel to move between a closed position and an open position. The drive wheel is configured to contact a sheet in the closed position and to not contact a sheet in the open position.
Claims7
A sheet transport system, comprising:
- a first idler wheel having a substantially rigid outer layer;
- a first drive wheel having a compliant outer layer, wherein the first drive wheel corresponds to the first idler wheel;
- a drive motor operably connected to the first drive wheel, wherein the drive motor is configured to cause the first drive wheel to rotate around a first shaft;
- and
- a first actuator operably connected to the first drive wheel and the drive motor, wherein the first actuator is configured to cause the first drive wheel and the drive motor to move between a closed position and an open position, wherein the first drive wheel is configured to contact a sheet in the closed position and to not contact a sheet in the open position.
