Entrance switch section

• One-sided printing paper and the two sided printing paper for printing the second side
which are loaded from the copier will be loaded to the intermediate transport section.
(forward entrance)
• Two-sided printing paper for printing the first side will not be loaded to the intermediate
transport section, but will switch back to the copier. In order to do this, the duplex guide
solenoid will switch the entrance, and transport the paper temporarily to the switch back
entrance. The feeding direction of the paper will be changed to return the paper to the
copier. (switch back entrance)
• Paper will be transported by the switchback motor drive installed to the duplex unit.
• When the duplex guide solenoid turns ON, the switch back paper guide will be pushed up
and the entrance will be switched to the switch back entrance.
• Switch back entrance will be detected by the entrance switch back sensor.
• The entrance will be switched to the forward entrance when a paper jam, a trouble, or
setting error occurs.
