The switchback solenoid is turned on by the time the top edge of paper passes by the paper jam sensor on the fuser unit. The
switching lever engages with the switching gear-B, and the rotation of rotation switching gear-B is locked. As a result, the rotation
from the BK motor is transmitted to the paper exit roller in order of numbers ( 1 - 8 ) through the double teeth gear. The arrows
indicate the rotation direction of each gears.

from the BK motor is transmitted to the paper exit roller in order of numbers ( 1 - 8 ) through the double teeth gear. The arrows
indicate the rotation direction of each gears.
Also, the switching lever moves the paper path switching guide in the direction of arrow (A) as shown in the figure-1. This advances
the sheet of paper between the paper exit roller and switchback pinch roller. The paper is fed to the output tray by the paper exit
roller and pinch roller. At the proper time, the switchback solenoid is turned off, which returns the switching lever to the home
position. The rotation switching gear is locked by the switching lever, and the rotation from the BK motor is transmitted to the paper
exit roller in order of numbers ( 1 - 8 ) through the double teeth gear. As a result, the paper exit roller rotates in the reverse direction.
The paper path switching guide also is moved in the direction of arrow (B) ( see figure-2 ) and returns to the home position. The
paper is fed to the auto duplex rollers in the optional Auto Duplex Unit through the paper guides along the paper path switching
guide. Further, the paper is fed to the registration roller by the auto duplex rollers and advanced to the fuser unit. After fusing, the
paper arrives the paper exit roller and is fed to the output tray by the paper exit roller.
