Trouble typeC1145: Trailing edge stopper motor drive malfunction (When FS-539 or FS-539SD is installed)
RankB
Trouble detection condition– The trailing edge stopper home sensor (PS20) is not turned OFF (unblocked) after the set period of time has elapsed after the trailing edge stopper drive starts from the home position.

– The trailing edge stopper home sensor (PS20) is not turned ON (blocked) after the laps of give time after the trailing edge stopper motor (M6) is energized when trailing edge stopper returned to the home position.
Trouble isolationStaple
Relevant electrical parts– Trailing edge stopper motor (M6)
– Trailing edge stopper home sensor (PS20)
– FS control board (FSCB)

Procedure

  1. Check the connector between M6-FSCB J5 for proper connection and correct as necessary.
  2. Check the connector of M6 for proper drive coupling and correct as necessary.
  3. Check the connector between PS20-relay CN13-FSCB J4 for proper connection and correct as necessary.
  4. PS20 I/O check, sensor check
    • Control signal: FSCB J4<A>-11 (ON)
    • Location of electrical component: FS-539/FS-539SD 14-C
  5. M6 operation check
    • Control signal: FSCB J5-13 to 16
    • Location of electrical component: FS-539/FS-539SD 15-K
  6. Replace M6.
  7. Replace FSCB.

Trouble typeC1145: Trailing edge stopper motor/Fr drive malfunction (When FS-540 or FS-540SD is installed)
RankB
Trouble detection condition– The trailing edge stopper sensor/Fr (PS10) is not turned OFF (unblocked) after the set period of time has elapsed after the trailing edge stopper drive starts from the home position.

– The trailing edge stopper sensor/Fr (PS10) is not turned ON (blocked) after the set period of time has elapsed after the trailing edge stopper motor/Fr (M12) is energized when the trailing edge stopper returned to the home position.
Trouble isolationStaple
Relevant electrical parts– Trailing edge stopper motor/Fr (M12)
– Trailing edge stopper sensor/Fr (PS10)
– FS control board (FSCB)

Procedure

  1. Check the connector between M12-relay CN5-FSCB J18 for proper connection and correct as necessary.
  2. Check the connector of M12 for proper drive coupling and correct as necessary.
  3. Check the connector between PS10-relay CN5-FSCB J18 for proper connection and correct as necessary.
  4. PS10 I/O check, sensor check
    • Control signal: FSCB J18-13 (ON)
    • Location of electrical component: FS-540/FS-540SD 6-D
  5. M12 operation check
    • Control signal: FSCB J18-14 to 17
    • Location of electrical component: FS-540/FS-540SD 6-D
  6. Replace M12.
  7. Replace FSCB.
