Contents

Trouble type	Stapler movement motor malfunction
Trouble code	C1106
Rank	B
Detection timing	<When FS-534 is installed> -The stapler home position sensor (Rear) (PS23) is not blocked or 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.
	<When FS-535 is installed> The stapler position sensor/1/2/3/4 (PS50/PS/51/PS52/PS53) is blocked or unblocked even after the set period of time has elapsed after the stapler movement motor (M13) is turned ON.
Trouble isolation	Staple
Relevant electrical parts	<When FS-534 is installed> -Side stapler movement motor (M13) -Stapler home position sensor (Rear) (PS23) -FS control board (FSCB)
	<When FS-535 is installed> -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)
