Finisher Control

Finisher Control is a term used to describe the resources that monitor and control the actions
and operations of the Finisher -- from paper entrance to paper stacking.
The Finisher PWB controls all Finisher functions, executes commands sent from the IOT CPU
PWB, and sends information back to the IOT CPU PWB. All Finisher components are con-
nected to the Finisher PWB. The IOT CPU PWB provides the logic and information processing
that is necessary for the printer to function, and the Finisher PWB provides the logic and infor-
mation processing that is necessary for the Finisher to function.

Every electrical component within the Finisher is connected to the Finisher PWB. Sensors in
the Finisher send status information to the Finisher PWB. The Finisher PWB processes this
information, shares it with the IOT CPU PWB, and compares it to timing tables stored in ROM.
Acting on the results of the processing, the Finisher PWB sends commands to the various Fin-
isher components; for example, switching on a motor or switching off a solenoid
