C3101 (bizhub 558/458)

 Contents

Trouble type	C3101: Pressure roller pressure failure
Rank	B
Trouble detection condition	C3101: •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 pressure by the pressure roller. •The fusing pressure home sensor (PS38) is not blocked even after the lapse of a predetermined period of time after the fusing pressure motor (M11) has started rotating during pressure by the pressure roller.
Trouble isolation	–
Relevant electrical parts	•Fusing unit • Fusing pressure motor (M11) • Fusing pressure home sensor (PS38) • MFP board (MFPB)(558)part# A9HGH02102 )(458)

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 558)
3. Check the connector between the fusing unit-relay CN104-MFPB CN12E for proper connection and correct as necessary. (bizhub 458)
4. PS38 I/O check, sensor check
   • Control signal: 558 MFPB CN22E-9 (ON), 458 MFPB CN12E-12 (ON)
   • Location of electrical component: 558 22-C, 458 24-C
5. M11 operation check
   • Control signal: MFPB CN15E<A>-7 to 10
   • Location of electrical component: 558 16-C, 458 19-C
6. Replace M11.  (558)(458) Part# A79K228101)
