Paper feed section

5.1.1

Vertical transport drive mechanism

• The paper feed 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 transport roller motor transports the paper through the vertical transport sec-
tion.
• 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 upper limit sensor then detects the upper limit position when the paper lifting plate is
raised.
• The empty sensor detects when paper in the drawer runs out.
• The polyethylene sheet and
a curled sheet of paper and guide, thereby preventing skewed feeding.
