Rank	B
Trouble detection condition	<When FS-533 is installed> -The stapler home sensor (PS110) is not turned OFF (unblocked) after the laps of given time after it started operating from the home position. -The stapler home sensor (PS110) is not turned ON (blocked) after the laps of give time after the stapler movement motor (M107) turned ON when it returned to the home position.
	<When FS-534 or FS-534SD is installed> -The stapler home position sensor (Rear) (PS23) is not turned ON (blocked) or OFF (unblocked) even after the set period of time has elapsed after the side stapler movement motor (M13) turned ON. -The stapler does not reach the specified position within the set period of time.
Trouble isolation	Staple
Relevant electrical parts	<When FS-533 is installed>Stapler movement motor (M107) -Stapler home sensor (PS110) -Stapler relay board (STREYB) -FS control board (FSCB)
	<When FS-534 or FS-534SD is installed> -Side stapler movement motor (M13) -Stapler home position sensor (Rear) (PS23) -FS control board (FSCB)

 Procedure

 When FS-533 is installed

1. Check the connector between M107-STREYB CN123 for proper connection, and correct as necessary.
2. Check the connector of M107 for proper drive coupling, and correct as necessary.
