E17 Circuit Diagram
1.
Block diagram
The circuit diagram shown on page 8/16 consists of the following connectors:
•
Connector CN6 that provides an interface between E17 board and NCU board.
•
Connector CN7 that provides an interface between E17 board and external electro-
mechanical devices (PC1 and PC2).
•
Connector CN9 that provides an interface between E17 board and OPE (O5W) unit.
Figure A3.1.7 shows an interface between E17 board and NCU board.
Figure A3.1.8 shows an interface between E17 board and OPE unit.
Figure A3.1.9 shows the related signals of PC1 and PC2.
2.
Function
1)
External status supervising interface (PC1/PC2)
External status is detected by the photocouplers (PC1/PC2) in the mechanism and the signal
is output to the input port of CPU via this interface circuit.
•
PC1:Presence of document on hopper.
When sub-power supply is applied to the fax machine, this signal is output to OPE
unit which will control the main-power supply.
•
PC2:Presense of document at scanning position.
