Paper feed

After the paper pickup operation, the paper picked up from either the Tray 2 cassette or MP tray is then fed to the fixing-and-delivery block.

1.The registration shutter corrects the skew-feeding of the paper that is picked up from the Tray 2 cassette or MP tray.

2.When the TOP sensor detects the leading edge of paper, the DC controller controls the rotational speed of the pickup motor to align with the leading edge of toner image on the ITB.

3.The toner image on the ITB is transferred onto the paper, and the paper is fed to the fusing-and- delivery block.
