Trouble typeC3101: Pressure roller pressure failure
RankB
Trouble detection conditionThe fusing pressure home sensor (PS38) is not turned ON (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 unitFusing pressure motor (M11)
• Fusing pressure home sensor (PS38)
• Expansion control board (EXCB)
• CPU board (CPUB)
• Base board (BASEB)

Procedure

  1. Check the connector between M11-relay CN112-EXCB CN14EX for proper connection and correct as necessary.
  2. Check the connector between the fusing unit-relay CN95, CN96-BASEB CN4E for proper connection and correct as necessary.
  3. Check the connector between EXCB CN2EX-BASEB CN12E for proper connection and correct as necessary.
  4. Check CPUB for proper installation and correct as necessary.
  5. PS38 I/O check, sensor check
    • Control signal: BASEB CN4E-3 (ON)
    • Location of electrical component: 7-C
  6. M11 operation check
    • Check code: 45
    • Multi code: 7, 8, 9
    • Control signal: EXCB CN14EX-11 to 14
    • Location of electrical component: 6-P
  7. Replace M11. (Part# A161M10300)
  8. Replace the fusing unit. (Part# AA2JR70300)
  9. Replace EXCB. (Part# AA2JH00500)
  10. Replace CPUB. (Part# AA2JH02N06)
  11. Replace BASEB. (Part# AA2JH02005)
