Contents
| Trouble type | Alignment plate motor/F home sensor malfunction | |
| Trouble code | C1103 | |
| Rank | B | |
| Detection timing | <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. | ||
| Trouble isolation | – | |
| Relevant electrical parts | <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) |
