(1) Paper conveying operation in duplex copying
Paper of which copying onto the reverse side is complete is conveyed to the switchback section, the eject motor switches
from nomal rotation to reverse rotation to switch the eject roller to reverse rotation, and the paper conveying direction is
reversed. Paper that has been switched back is conveyed to the duplex section via the eject roller and the switchback roller.
Paper that has been conveyed to the duplex section is conveyed to the paper feed section again by rotation of the upper
duplex feed roller and the lower duplex feed roller and copying onto the front side is performed.
