7. 2. 3 Measures against Service Call Errors
7. 2. 3. 1 "E-01" Fuser Temperature Rising Error
When "E-01" must not be detected when diagnosing the KIP9000, mask it in the Error Mask Mode.
Its Mask Code is "00". See [8.1.8 Error Mask Mode (Sub Mode 7)] on page 8-114 for the detail.

Checking matter
1 Is the harness connected to each
IR Lamps (H1 & H2), SSR (SSR1
& SSR2) and Thermistor (TH1)?
2 Plug out the KIP9000 and check
the resistance of each IR Lamp.
Is there any resistance?
3 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?
4 Check the voltage between
Terminals 0 and 1 on each Relay
2 and Relay 3.
Is it 24V?
5 Check the voltage at the Terminal
1 on each Relay 2 and Relay 3.
Is it 0V?
6 Does the gray lead wire on the
coil side of Relay 2 show 24V?
And does the orange lead wire on
the same place show 0V?
7 Check the voltage between
Terminals 4 and 8 on the IR Lamp
side of Relay 2.
Is it 230VAC?
8 Check the voltage at both J253-1
and J253-3 on the Phase Control
PCB 2.
Does J253-3 show 0V when
J253-1 shows 0V?
9 Check the voltage between
Terminals 4 and 8 on the IR Lamp
side of Relay 3.
Is it 230VAC?
10 Check the voltage at both J253-2
and J253-4 on the Phase Control
PCB 2.
Does J253-4 show 0V when
J253-2 shows 0V?
11 Can the error be fixed by
replacing the Main Control PCB?
Result
No Connect it.
No Replace the IR Lamps.
Yes 1. Clean the Thermistor 1 and
reinstall it correctly.
2. If the error still occurs, replace
the Thermistor 1.
(Tracing)
No Check if the interlock can correctly
open and close.
No 1. Replace the Temperature Detect
PCB.
2. If the error still occurs, replace
the Thermistor 2.
No Replace the DC Driver PCB.
No Replace the Relay 2.
No Replace the Phase Control PCB 2.
Yes Replace the SSR1
No Replace the Relay 3.
No Replace the Phase Control PCB 2.
Yes Replace the SSR2
Yes OK
