Trouble type	C3101: Pressure roller pressure failure
Rank	B
Trouble detection condition	The 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)
