1. This chapter discusses the purpose and role of each of the puncher unit’s functions, and the
principles of operation used for the puncher unit mechanical and electrical systems. It also ex-
plains the timing at which these systems are operated.
The  
 symbol in drawings indicates transmission 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 puncher unit, “1” indicates a high signal voltage level,
while “0” indicates a low signal voltage level. Voltage values differ according to circuit.
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.

BASIC OPERATION
A.
 Outline
The puncher unit (option) is attached on the feed path between the host machine and the finisher.
The puncher unit does not have a paper feed mechanism. Paper from the host machine is fed by
feed drive from the finisher via the puncher unit. When the trailing edge of the paper from the host
machine reaches the puncher unit, the paper stops temporarily, and the punch shaft is rotated to punch
the trailing edge of the paper. This operation is controlled by the finisher controller PCB, and each of
the parts on the finisher is driven by the punch driver PCB.
