Causes: Alignment plate motor/F (M11) 2 staples alignment motor home sensor/F (PS17) FS control board (FSCB)
Remedy: 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 PS17 I/O check, sensor check FSCB CN20<A>-6 (ON) FS-526 L-11 4 M1 operation check FSCB CN19-1 to 4 FS-526 D-13 5 Change M1 6 FSCB ICP4 conduction check 7 Change FSCB
Code: C1104
Description: Paper exit roller drive motor malfunction <When FS-526 is installed> • The exit roller motor (M4) lock signal remains set to H for a set period of time while the exit roller motor (M4) is turning.
Causes: Exit roller motor (M4) FS control board (FSCB)
Remedy: 1 Check the motor and sensor connectors for proper connection, and correct as necessary. 2 Check the connector of M4 for proper drive coupling, and correct as necessary. 3 M4 operation check FSCB CN18-3 to 10 FS-526 D-12 4 Change M4 5 FSCB ICP2 conduction check 6 Change FSCB
Code: C1105
Description: Paper exit auxiliary roller motor malfunction <When FS-526 is installed> • The paper output roller home sensor (PS10) is turned neither ON nor OFF even after the set period of time has elapsed after the paper output roller motor (M6) is turned ON.
Causes: Paper output roller motor (M6) Paper output roller home sensor (PS10) FS control board (FSCB)
Remedy: 1 Check the motor and sensor connectors for proper connection, and correct as necessary. 2 Check the connector of M6 for proper drive coupling, and correct as necessary. 3 PS10 I/O check, sensor check FSCB CN21<A>-9 (ON) FS-526 L-7 4 M6 operation check FSCB CN13-1 to 6 FS-526 D-5 5 Change M6 6 FSCB ICP6 conduction check 7 Change FSCB
Code: C1106
Description: Side-staple stapler drive malfunction <When FS-526 is installed> • The stapler position sensor/1/2/3/4 (PS50/ PS/51/PS52/PS53) is turned neither ON nor OFF even after the set period of time has elapsed after the 2 staples stapler movement motor (M13) is turned ON.
Causes: 2 staples stapler movement motor (M13) Stapler position sensor/1 (PS50) Stapler position sensor/2 (PS51) Stapler position sensor/3 (PS52) Stapler position sensor/4 (PS53) FS control board (FSCB)
Remedy: 1 Check the motor and sensor connectors for proper connection, and correct as necessary. 2 Check the connector of M13 for proper drive coupling, and correct as necessary. 3 PS50 I/O check, sensor check FSCB CN20<B>-3 (ON) FS-526 L-13 4 PS51 I/O check, sensor check FSCB CN20<B>-6 (ON) FS-526 L-13 5 PS52 I/O check, sensor check FSCB CN20<B>-9 (ON) FS-526 L-13 to 14 6 PS53 I/O check, sensor check FSCB CN20<B>-12 (ON) FS-526 L-14 7 M13 operation check FSCB CN15-3 to 8 FS-526 D-11 to 12 8 Change M13 9 FSCB ICP5 conduction check 10 Change FSCB
