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-relay CN112-MFPB CN15E for proper connection and correct as necessary.
2. Check the connector between the fusing unit-relay CN96-MFPB CN22E for proper connection and correct as necessary. (bizhub C658/C558)
3. Check the connector between the fusing unit-relay CN104-MFPB CN12E for proper connection and correct as necessary. (bizhub C458)
4. PS38 I/O check, sensor check
   • Control signal: C658/C558 MFPB CN22E-9 (ON), C458 MFPB CN12E-12 (ON)
   • Location of electrical component: C658/C558 22-C, C458 24-C
5. M11 operation check
   • Control signal: MFPB CN15E<A>-7 to 10
   • Location of electrical component: C658/C558 16-C, C458 19-C
6. Replace M11.(Part# A161M10300)
7. Replace the fusing unit. (bizhub C658/C558 Part# A79JR71066 / bizhub C458 Part# A79MR70222)
8. Replace MFPB. (C458 Part# A79MH02102 / C558 or C658 Part # A79JH02102)
