C1070 error c3511

[CKiiza]

Hey all,

Have a C1070 which warms up endlessly but I noticed the low fusing roller lamp doesn't come on. I've checked the connectivity to all the lamps and it's continous.
Every now and then it throws up a c3103 and C3511 intermittently.

Unfortunately I don't have a service manual to work with so I'm working in the grey.

Any help please

From SM:

Code:
C-3511*
Classification:
Main body: Fusing temperature difference abnormality
Cause:
The temperature difference between the fusing temperature sensor/1 (TH1) and the fusing temperature sensor/2 (TH2) stays 100°C or more for a specified period of time.
Measures to take when an alert occurs:
The main body and the option stop immediately to deactivate the main relay.
Estimated abnormal parts:
• Fusing unit
• Printer control board (PRCB)
• DC power supply/1 (DCPS1)
• Fusing control board/1 (FUSCB1) (Only for Europe)
• Fusing control board/2 (FUSCB2) (Only for Europe)
• Fusing control board/3 (FUSCB3) (Only for Europe)
• Fusing heater lamp/1 (L1)
• Fusing heater lamp/2 (L2)
• Fusing heater lamp/3 (L3)
• Fusing temperature sensor/1 (TH1)
• Fusing temperature sensor/2 (TH2)
• Thermostat/1 (TS1)
• Thermostat/2 (TS2)
Correction
WARNING
• Be sure to select the DIPSW3-1 to 0 after you replace the defective parts. If DIPSW3-1 is selected to 0 before defective parts
are fixed, it possibly cause a fire.
Note
• The message "Please call service" is displayed on the panel.
Solution:
1. Check that the front door is not opened or closed frequently, and wait for several minutes while the front door is closed.
2. Check the fusing roller, and repair it when there is any abnormality such as a paper wrap.
3. Check the connection between the rear side connector of the fusing unit and the main body side connector, and repair it when there is
any abnormality.
4. Check the connector connection and the wiring between the fusing temperature sensor and the PRCB, and repair it when there is any
abnormality.
5. Check the connector connection and the wiring between the fusing heater lamp and the DCPS1. Then repair it when there is any
abnormality. (Wiring diagram: Main body (1/4): 3-C, 3-D)
6. Check the connector connection and the wiring among the fusing heater lamp, the FUSCB1, the FUSCB2, the FUSCB3, and the
DCPS1. Then repair it when there is any abnormality. (Wiring diagram: Main body (4/4): 10-A, 10-C, 10-D) (Only for Europe)
7. Check the conduction of TS1 and TS2, and repair it when there is any abnormality.
8. Check the installation condition of the fusing heater lamp and ON or OFF by the I/O, and repair it when there is any abnormality.
(Wiring diagram: Main body (1/4): 3-C, 3-D)
9. Check the installation condition of TH1 and TH2, and the temperature of I/O. Then adjust it when there is any abnormality. (Wiring
diagram: Main body (1/4): 1-E)
10. Replace TH1 and TH2.
11. Replace TS1 and TS2.
12. Replace the fusing heater lamp assy/Up.
13. Replace FUSCB1, FUSCB2, and FUSCB3. (Only for Europe)
14. Replace DCPS1.
15. Replace PRCB.
16. Replace the fusing unit

check the connectors on the back of the fusing unit and the machine, maybe a piece of paper is caught there.

##Trobleshooting
*Model - KM bizhub PRESS C1060
*Symptom
C-3511 (Fusing belt temperature sensor 1,2 Temperature difference more than 100° difference)
C-3515 (Fusing belt temperature sensor 2 defect detection)
C-3510 (Fusing belt temperature sensor 2,3 Temperature difference more than 100° difference)
- Occurrence of the above error codes sequentially
- Error code reoccurs even after Trouble Rest the failure
* Cause
3 error codes common to TS2 (ThermoStat2)
*Solution
Disassemble TS2 from fusing unit and throw it to floor to shock.
Install TS2 and perform Trouble Reset(Software DIPsw 3-1=OFF)

Few days ago on C1060l i have C3511 and 3513 after warming up.
Replaced fusing temperature sensor/1 (non contact sensor) ,problem solved.
