(2) Paper feeder (PF-740(B))
(2-1) Paper deck section
The deck can load 1750 sheets paper (64 g/m2) or 1500 sheets paper (80 g/m2). Paper from the deck is
picked up by rotating the pickup roller and is conveyed to the main unit by rotating the paper feed roller.
Multi-feeding is also prevented by the effect of the retard roller.
The paper feeder is comprised of the right- and left-hand cassettes and their feeding units, and the paper
feeding section for the left-hand cassette.
The paper loaded on the lifting plate in the right-hand cassette is picked up one by one by PF forwarding
pulley 1, PF paper feed pulley 1 and PF separation pulley 1. And then the PF paper feed roller 1 feeds the
paper into the main unit. The paper fed by the left-hand cassette is separated in the similar manner and
fed out by the conveying roller into the main unit.
