Skew Correction
Description
This machine can correct paper skew without lowering throughput.
Skew is corrected as follows.
1. The paper leading edge pushes against the Registration Shutter to align the leading edge of the paper.
2. The trailing edge of the paper is fed and slack is generated at the leading edge of the paper.
3. When the trailing edge is fed even further, the paper leading edge for which slack was generated pushes up the Registration
Shutter and then the paper is fed to the Registration Roller while the paper leading edge is aligned.
