11.1.2. Finisher Unit Operation
11.1.2.1. Basic Operation
This chapter discusses the purpose and role of each of the Finisher's functions, and the principles of
operation used for the Finisher mechanical and electrical systems. It also explains the timing at which these
systems are operated.
The symbol in the drawings indicates transmission of mechanical drive, and signals marked by
together with the signal name indicates the flow of electrical signals.
In descriptions of digital circuits of the Finisher, "1" indicates a high signal voltage level, while "0" indicates a
low signal voltage level. Voltage values differ according to the circuit.
A microprocessor is used in the Finisher to control all the finishing functions.
Descriptions in this chapter also assume that PCBs will not be repaired at user sites. For this reason,
descriptions of circuits on PCBs is limited to block diagrams. Two types of block diagrams are provided for
separate functions: diagrams indicating details from sensors up to input sections of major PCBs, and
diagrams indicating details from the output sections of major PCBs up to the components.
