Trouble type	C1184: Paper delivery control motor drive malfunction (When FS-539 or FS-539SD is installed)
Rank	B
Trouble detection condition	-The paper delivery control home sensor (PS28) is not turned OFF (blocked) after the set period of time has elapsed after the paper detection lever drive starts from the home position. -The paper delivery control home sensor (PS28) is not turned ON (unblocked) after the set period of time has elapsed after the paper delivery control motor (M12) is energized when the paper detection lever returned to the home position.
Trouble isolation	–
Relevant electrical parts	-Paper delivery control motor (M12) -Paper delivery control home sensor (PS28) -FS control board (FSCB)

Procedure

1. Check the connector between M12-FSCB J14 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 PS28-relay CN1-FSCB J14 for proper connection and correct as necessary.
4. PS28 I/O check, sensor check
   • Control signal: FSCB J14<A>-12 (ON)
   • Location of electrical component: FS-539/FS-539SD 2-C
5. M12 operation check
   • Control signal: FSCB J14<A>-9 to 12
   • Location of electrical component: FS-539/FS-539SD 1-C
6. Replace M12. (Part# A3EPPPAA00)
7. Replace FSCB. (Part# AAR4PP8201)
