Trouble type	C8101: Before reading pressure welding alienation mechanism (When DF-629 or DF-704 is installed)
Rank	B
Trouble detection condition	<When DF-629 is installed> • During a pressure motion being performed, the reading roll position sensor (PS11) output does not change from H to L. • During a retraction motion being performed, the reading roll position sensor (PS11) output does not change from L to H.
	<When DF-704 is installed> • During a pressure motion being performed, the reading roll position sensor (PS4) output does not change from H to L. • During a retraction motion being performed, the reading roll position sensor (PS4) output does not change from L to H.
Trouble isolation	–
Relevant electrical parts	<When DF-629 is installed> • Reading roll release motor (M5) • Reading roll position sensor (PS11) • DF control board (DFCB)
	<When DF-704 is installed> • Reading roll release motor (M4) • Reading roll position sensor (PS4) • DF control board (DFCB)

 Procedure

 When DF-629 is installed

1. Check the connector between M5-DFCB J18 for proper connection and correct as necessary.
2. Check the connector of M5 for proper drive coupling and correct as necessary.
3. Check the connector between PS11-DFCB J18 for proper connection and correct as necessary.
4. PS11 I/O check, sensor check
   • Control signal: DFCB J18-3 (ON)
   • Location of electrical component: DF-629 1-G
5. M5 load check
   • Check code: 60
   • Multi code: 81, 82
   • Control signal: DFCB J18-4 to 5
   • Location of electrical component: DF-629 2-G
6. Replace M5. (Part# A3CFPP6J00)
7. Replace DFCB. (Part# A87RPP1700)

 When DF-704 is installed

1. Check the connector between M4-DFCB J18 for proper connection and correct as necessary.
2. Check the connector of M4 for proper drive coupling and correct as necessary.
3. Check the connector between PS4-DFCB J18 for proper connection and correct as necessary.
4. PS4 I/O check, sensor check
   • Control signal: DFCB J18-3 (ON)
   • Location of electrical component: DF-704 1-G
5. M4 load check
   • Check code: 60
   • Multi code: 81, 82
   • Control signal: DFCB J18-4 to 5
   • Location of electrical component: DF-704 1-G
6. Replace M4. (Part# A3CEPP5700)
7. Replace DFCB. (Part# A85GPP0M00)
