Trouble type	Alignment plate motor/Fs malfunction
Trouble code	C1103
Rank	B
Detection timing	<When FS-533 is installed> -The alignment plate home sensor/F (PS108) is not unblocked after the set period of time has elapsed after the plate drive starts from the home position. -The alignment plate home sensor/F (PS108) is not blocked after the set period of time has elapsed after the alignment motor/F (M105) is turned ON to return the plate to the home position.
	<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.
