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