Causes: <When FS-534 is installed> • Main tray up/down motor (M11) • Main tray upper position sensor/R (PS26) • Main tray upper position sensor/F (PS27) • Main tray full detection sensor (PS29) • Main tray upper position detect switch (SW2) • FS control board (FSCB) <When FS-535 is installed> • Main tray up/down motor (M5) • Main tray upper limit sensor/in (PS44) • Main tray upper limit sensor/out (PS45) • Staple paper exit top surface sensor (PS7) • FS control board (FSCB)
Remedy: When FS-534 is installed: 1 Check the motor and sensor connectors for proper connection, and correct as necessary. 2 Check the connector of M11 for proper drive coupling, and correct as necessary. 3 PS26 I/O check, sensor check FSCB J14<A>-5 (ON) FS-534 2-C 4 PS27 I/O check, sensor check FSCB J14<B>-8 (ON) FS-534 3-C 5 PS29 I/O check, sensor check FSCB J14<A>-8 (ON) FS-534 4-C 6 SW2 operation check FSCB J10-1 to 2 FS-534 8-K 7 M11 operation check FSCB J9<A>-9 to 10 FS-534 10-C to D 8 Replace M11 9 Replace FSCB. When FS-535 is installed: 1 Check the motor and sensor connectors for proper connection, and correct as necessary. 2 Check the connector of M5 for proper drive coupling, and correct as necessary. 3 PS44 I/O check, sensor check FSCB CN24-2 (ON) FS-535 8-L 4 PS45 I/O check, sensor check FSCB CN18-1 to 3 FS-535 13-D 5 PS7 I/O check, sensor check FSCB CN23-15 (ON) FS-535 13-L 6 M5 operation check FSCB CN22-1 to 11 FS-535 5-L 7 Replace M5 8 FSCB ICP1 conduction check 9 Replace FSCB
Code: C1103
Description: Alignment plate motor/Fr’s malfunction. <When FS-534 is installed> • The alignment plate/F home sensor (PS12) is not unblocked after the set period of time has elapsed after the plate drive starts from the home position. • The alignment plate/F home sensor (PS12) is not blocked after the set period of time has elapsed after the alignment motor/front (M7) is turned ON to return the plate to the home position, • The alignment plate/F does not reach the specified position within the set period of time.<When FS-535 is installed> The alignment plate motor home sensor/Fr (PS17) is not blocked even after the set period of time has elapsed while the Alignment plate motor/Fr (M11) is energized.
Causes: <When FS-534 is installed> • Alignment motor/Front (M7) • Alignment plate/F home sensor (PS12) • FS control board (FSCB) <When FS-535 is installed> • Alignment plate motor/Fr (M11) • Alignment plate motor home sensor/F (PS17) • FS control board (FSCB)
Remedy: When FS-534 is installed: 1 Check the connector between M7-FSCB J4 for proper connection and correct as necessary. 2 Check the connector of M7 for proper drive coupling, and correct as necessary. 3 Check the connector between PS12-FSCB J4 for proper connection and correct as necessary. 4 PS12 I/O check, sensor check FSCB J4<B>-4 (ON) FS-534 13-C 5 M7 operation check FSCB J4<A>-5 to 8 FS-534 11-C to D 6 Replace M7 7 Replace FSCB. When FS-535 is installed: 1 Check the connector between M11-FSCB CN19 for proper connection and correct as necessary. 2 Check the connector of M11 for proper drive coupling, and correct as necessary. 3 Check the connector between PS17-FSCB CN20 for proper connection and correct as necessary. 4 PS17 I/O check, sensor check FSCB CN20-6 (ON) FS-535 12-D 5 M11 operation check FSCB CN19-1 to 4 FS-535 10-D 6 Replace M11 7 FSCB ICP4 conduction check 8 Replace FSCB
