Code Cause• Scanner locked sensor (PS48; fault)• Scanner locking solenoid (SL1; fault)• DC controller PCB (fault)• Scanner motor cooling fan(FM9;fault)• DC controller PCB (fault)• Lamp regulator (fault)• DC controller PCB (fault)• DC controller PCB (fault)• DC controller PCB (fault)• Control panel PCB (fault)• DC controller PCB (fault)• DC controller PCB (fault)• RDF controller PCB• Connector (poor contact)• 24V power supply (poor contact)• Sorter controller PCB (fault)• Connector (poor connection)• 24V power supplyDescription• During copying in stream readingmode, the scanner locked sensorsignal (SCLK) is not generated with-in a specific period of time.• The scanner does not stop at thescanner original leading edge 2sensor (PS4).• The rotation of the scanner motorcooling fan is not detected for aspecific period of time.• During standby, the scanning lampturns on.• During copying, the scanning lampturns off.• The lamp ON detection signal(CVRON) is generated although thescanning lamp ON signal (LAON) is‘0’.• There is an error in the communica-tion between the microprocessormaster (Q156) and the microproces-sor slave (Q140) on the DC con-troller PCB.• An error has occurred in the com-munication between the master(Q156) on the microprocessor onthe DC controller PCB and themicroprocessor on the control panelPCB.• At power-on, the copier detects anerror in communication betweencopier and external device becauseof an error in the copier’s communi-cation IC (IPC;Q158).• After power-on, the copier detectsan error in communication betweencopier and external device becauseof an error in the copier’s communi-cation IC (IPC;Q158).• The communication control IC (IPC)on the RDF controller PCB goes outof order.• The communication control IC (IPC)on the sorter controller PCB goesout of order.E240E243E710E711E712E214E713E220E213CHAPTER 11 TROUBLESHOOTING11-263COPYRIGHT © 1997 CANON INC.
