1. This chapter discusses the purpose and role of each of the finisher’s functions, and the prin-
ciples of operation used for the finisher mechanical and electrical systems. It also explains the
timing at which these systems are operated. The
timing at which these systems are operated. The
symbol in drawings indicates transmis-
sion of mechanical drive, and signals marked by
together with the signal name indicates
the flow of electrical signals.
2. In descriptions of digital circuits on the finisher, “1” indicates a high signal voltage level, while
“0” indicates a low signal voltage level. Voltage values differ according to circuit.
A microprocessor is used on the finisher. A description of microprocessor operation is omitted
in this chapter as it is practically impossible to check internal operation of the microprocessor.
in this chapter as it is practically impossible to check internal operation of the microprocessor.
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 dia-
grams 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 the loads.
