3. After double feed paper is removed by the Multi-purpose Tray Separation Pad, paper is fed into the machine. Note that the
presence of paper on the Multi-purpose Tray is detected by the Multi-purpose Tray Media Presence Sensor (PS3), and
printing is not performed if there is no paper.

Skew Correction
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.
