Figure 2-1-5 Upper exit roller forward/reverse drive mechanism
The forward/reverse mechanism for the upper exit roller is composed of the planetary gear assemblies A (A-1, A-2 and A-
3) and B (B-1, B-2 and B-3), a switchback solenoid, and a latch lever, and it uses the driving force that is transmitted from
the main motor to the upper exit roller in order to switch between forward and reverse rotation.
In the case of 1-sided (normal) printing, the latch to the latch lever catches on gear B-1, thus stopping planetary gear
assembly B from functioning. This allows planetary gear assembly A to function and a forward driving force is transmitted
to the exit roller gear through the idle gear, thus causing the upper exit roller to turn in a forward direction.
However, in the case of duplex (2-sided) printing, the latch lever moves through the operation of the switchback solenoid
and catches on gear A-1, thus stopping planetary gear assembly A from functioning. This allows planetary gear assembly
B to function and a reverse driving force is transmitted to the exit roller gear through the idle gear, thus causing the upper
exit roller to turn in a reverse direction.
