5.TECHNICAL TROUBLESHOOTING
5.1THEORY OF OPERATION
The CANON Stream Punch is a machine that punches various die set hole patterns into single sheets of paper. The machine is placed between a printer / copier and a finisher. There are two paper paths. One is the bypass section, which does not punch paper. The other is the punch path. The punch path can be selected by pressing the green button on the top of the Stream Punch.
The Stream Punch consists of several input / output devices to operate the machine functions. The system intelligence is a Microchip
Refer to the electrical wiring information, when reading the following material.
INPUTS:
