7. 2. 3. 2 "E-02" Fuser Over-heating Error
When "E-02" must not be detected when diagnosing the KIP9000, mask it in the Error Mask Mode.
Its Mask Code is "01". See [8.1.8 Error Mask Mode (Sub Mode 7)] on page 8-114 for the detail.
Cause Order
Harness
SSR1
SSR2
Thermistor 1 (TH1)
Phase Control PCB 2
(PW6125 02)
Main Control PCB
(PW11520)
Checking matter
1 Is the harness connected to each
IR Lamps (H1 & H2), SSR (SSR1
& SSR2) and Thermistor (TH1)?
2 While checking the fuser
temperature (data No.00) in the
Data Monitoring Mode of Service
Mode, check the voltage at J253-
3 on the Phase Control PCB 2
(PW6125 02).
Does the temperature gradually
rise when the J253-3 shows 24V?
3 While checking the fuser
temperature (data No.00) in the
Data Monitoring Mode of Service
Mode, check the voltage at J253-
4 on the Phase Control PCB 2
(PW6125 02).
Does the temperature gradually
rise when the J253-4 shows 24V?
4 Check the fuser temperature (data
No.00) in the Data Monitoring
Mode of Service Mode, and
compare it with the setting value
of fuser temperature specified in
each of the following service
mode items.
4-10: Fusing temperature (PPC)
4-11: Fusing temperature
4-12: Fusing temperature (Film)
Are the detected temperature and
setting temperature greatly
different from each other?
5 1. Check the voltage at both
J253-2 and J253-4 on the
Phase Control PCB 2.
Does J253-4 show 24V when
J253-2 shows 5V?
2. Check the voltage at both
J253-1 and J253-3 on the
Phase Control PCB 2.
Does J253-3 show 24V when
J253-1 shows 5V?
6 Can the error be fixed by
replacing the Main Control PCB?
7-17
Result
No Connect it.
Yes Replace the SSR1.
Yes Replace the SSR2
No Replace the Thermistor 1 with the
new one.
(Tracing)
No Replace the Phase Control PCB 2.
Yes OK
