Paper Feed Section

5.1.1

Vertical transport drive mechanism

• The Paper Feed Motor drives the Pick-up Roller and Paper Take-up Roller to take up and
feed a sheet of paper into the main unit.
• Then, the Transport Roller Motor transports the paper through the vertical transport sec-
tion.
• The Pick-up Roller takes up sheets of paper and the Paper Take-up and Separation Roll-
ers ensure that only one sheet of paper is separated and fed into the main unit.
• When the drawer is slid in, the lever is pushed to lower the Pick-up Roller.
• The Lift-up Upper Limit Sensor then detects the upper limit position when the paper lifting
plate is raised.
• The Paper Empty Sensor detects when paper in the drawer runs out.
• The polyethylene sheet and
between a curled sheet of paper and guide, thereby preventing skewed feeding.
