From Punch To Compiler Unit Assembly - Lexmark X850e Service Manual

From punch to compiler unit assembly

The media is transferred to the compiler unit assembly by the buffer roll assembly (driven by the motor (buffer/
transport)) and by the lower media exit roll assembly (driven by the drive motor (exit)).
When the first media reaches the compiler unit assembly, the media eject clamp motor is activated to lower the
media eject clamp so that the media eject clamp and the media eject shaft assembly can clamp the media.
Thus, the media transferred from the punch unit is held by the media eject shaft assembly and the media eject
clamp (driven by the media eject motor assembly) and is fed to the exit.
When the media trailing edge passes through the sensor (lower media exit), the media eject motor assembly
starts reverse rotation to return the media to the compiler unit assembly.
When the following media reaches the compiler unit assembly, the media eject clamp is raised, and the media
that has passed through the lower media exit roll assembly falls on the compiler unit assembly.
At this time, the three main paddles are rotated by the main paddle shaft assembly to feed the media so that the
media trailing edge butts against the rear wall of the compiler unit assembly.
The sub paddle solenoid of the media eject unit assembly is activated to lower the sub paddle so that the media
can be fed to the compiler unit assembly.
