Trouble typeC3101: Pressure roller pressure failure
RankB
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 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)

 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)
