Skew-correction mechanism (registration)
This mechanism corrects the skew of paper that is fed to the device. The device uses a registration
shutter method to avoid decreasing throughput. The skew-correction mechanism operates in the
following sequence:
1. The leading edge of media encounters the registration shutter when the media is fed to the
registration roller.
2. The media is warped because the shutter is not opened unless acted upon by an outside source.
The feed roller keeps pushing the media toward the shutter.
3. The stiffness of the paper being warped lifts the registration shutter and the paper passes through
the shutter. The skew-feed is corrected without decreasing the throughput.
