Step Check Yes No
Possible causative parts:
• Fuser Assembly (PL7.1.1)
• Heater Harness Assembly (PL7.1.5)
• Top Harness Assembly (PL18.2.5)
• LVPS (PL18.1.34)
• MCU Board (PL18.1.13)
1 Check the Fuser Assembly installation
Are the Fuser Assembly, and the drawer connector (DP/J281)
of the printer installed properly (without a bent pin, or any
foreign or burnt objects, etc.)?
Go to step 2. Reinstall the
Fuser Assembly.
2 Check the Fuser Assembly connection
Check the connection between the Fuser Assembly and the
MCU Board, and the connection between the Fuser Assembly
and the LVPS.
Are P/J281, P/J28, and P/J47 connected securely?
Go to step 3. Connect P/J281,
P/J28, and P/J47
securely.
3 Check the connections between LVPS and the MCU Board
Check the connection between the LVPS and the MCU Board.
Are P/J508 and P/J29 connected securely?
Go to step 4. Connect P/J508
and P/J29
securely.
4 Check the Heater Harness Assembly continuity.
Is each cable of P/J281<=>P/J47 continuous?
Go to step 5. Replace the
Heater Harness
Assembly.
5 Check the Top Harness Assembly continuity.
Is each cable of P/J281<=>P/J28 continuous?
Go to step 6. Replace the Top
Harness
Assembly.
6 Check the power to the Fuser Assembly (+5 VDC)
Check if the voltage between the MCU Board ground and the
P/J28-2 pin is about +5 VDC.
Go to step 7. Refer to “+5 VDC
Power FIP” on
page 2-223.
7 Check after replacing the Fuser Assembly
Replace the Fuser Assembly.
Does the error still occur?
Go to step 8. Finished.
8 Check after replacing the LVPS
Replace the LVPS.
Does the error still occur?
Replace the MCU
Board.
Finished.
