Paper Feed Section

5.1.1

Paper Feed drive mechanism

• The Take-up Motor drives the Pick-up Roller and Paper Feed Roller to take up and feed a
sheet of paper into the main body.
• Then, the Vertical Transport Motor transports the paper through the vertical transport
section.
• The Pick-up Roller takes up sheets of paper and the Paper Feed and Separation Rollers
ensure that only one sheet of paper is separated and fed into the main body.
• When the drawer is slid in, the lever is pushed to lower the Pick-up Roller.
• The Lift-Up Upper 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.
