The CPU on the machine's finisher controller PCB is equipped with a mechanism to check the machine condition as
needed; when it detects a fault, the machine communicates the fact to the host machine in the form of a code and a
detail code.
The host machine indicates the code on its control panel. (The detail code may be checked in the host machine's
service mode.)
