Trouble type	C3103: Pressure roller release failure
Rank	B
Trouble detection condition	• The encoder pulse does not change even after the lapse of a predetermined period of time after the fusing pressure motor (M11) has started rotating during retraction of the pressure roller. • The fusing pressure home sensor (PS38) is not unblocked even after the lapse of a predetermined period of time after the fusing pressure motor (M11) has started rotating during retraction of the pressure roller.
Trouble isolation	–
Relevant electrical parts	• Fusing unit  • Fusing pressure motor (M11)  • Fusing pressure home sensor (PS38)  • MFP board (MFPB)

 Procedure

1. Check the connector between M11-MFPB CN15EA for proper connection and correct as necessary.
2. Check the connector between the fusing unit-relay CN98, CN99, CN104-MFPB CN13E for proper connection and correct as necessary.
3. PS38 I/O check, sensor check
   • Control signal: MFPB CN13E-12 (ON)
   • Location of electrical component: 11-C
4. M11 operation check
   • Control signal: MFPB CN15EA-5 to 8
   • Location of electrical component: 6-C
5. Replace M11. (Part# A7PUM10700)
6. Replace the fusing unit. (PART# A161R71888)
7. Replace MFPB. (Part# A9HJH02102)
