The switchback solenoid [F] turns on before the leading edge of the paper passes
the paper exit sensor (Figure 1).
• The switching lever [G] engages and locks the switching gear B [E].
• The BK motor drives the paper exit roller [B].
• The switching lever shifts the paper path switching guide [A] to the right. This
feeds the paper between the paper exit roller and the switchback pinch roller
[C]. The paper is sent to the exit tray, but is not released. Next, the
switchback solenoid turns off (Figure 2).
• The switching lever returns to its home position, and locks switching gear A
[H].
• The BK motor drives the paper exit roller. As the paper is positioned above
the exit roller, it is fed through in the opposite direction.
• The junction gate moves back to its home position. The paper passes
through the duplex unit, which then feeds the paper to the registration roller.
