05H) Heat Roll Paper Winding Fail; 06H) Warm Up Time Fail; 07H) Fusing Unit On Time Fail - Fuji Xerox DocuCentre SC2020 Service Manual

DC SC2020
Version 1.1
Fusing Unit NC Sensor detected temperature that is the specified value or more for 10 consecutive times.
NOTE: . To release this Fail, clear NVM[759-122] (High Temperature Abnormality Detection History) [0]
after removing the cause and turn the Power Off/On. The relationship between the displayed value and
the sensor that detected the high temperature error is as follows:
• 0: Normal
• 1: Abnormally high temperature of Fusing Unit NC Sensor
• 2: Abnormally high temperature of Fusing Unit Thermistor
• 3: Abnormal temperature increase of Fusing Unit NC Sensor, Fusing Unit Thermistor
Check Items
• Turn OFF the power and remove the Fusing Unit. Check whether foreign substances or paper is
wound around the Heat Roll.
• Check to see if DRIVE PWB Connector
Procedure
Turn the Power OFF and remove DRIVE PWB connector J511.
Calculate the resistance between P2-1 Pin and P2-3 of DRIVE PWB side.. Is the resistance infinite?
Y N
Replace DRIVE PWB. (PL 18.2)
Replace the following parts in sequence:
• Fusing Unit (PL 7.1)
• LVPS (PL 18.3)
• DRIVE PWB (PL 18.2)
• ESS PWB (PL 18.2)
After replacing the Fusing Unit, enter CE Mode, go to Printer Diag > Parameter > Life > Fusing Unit Print
Count / Fusing Unit Time Count and initialize the Life Counters.

010-397 (05h) Heat Roll Paper Winding Fail

BSD-ON:CH10.3
Detected the paper was wrapped around the Heat Roll from the monitor value of Fusing Unit Thermistor
and NC Sensor.
NOTE: . To release this Fail, clear NVM[759-122] (High Temperature Abnormality Detection History) [0]
after removing the cause and turn the Power Off/On. The relationship between the displayed value and
the sensor that detected the high temperature error is as follows:
• 0: Normal
• 1: Abnormally high temperature of Fusing Unit NC Sensor
• 2: Abnormally high temperature of Fusing Unit Thermistor
• 3: Abnormal temperature increase of Fusing Unit NC Sensor, Fusing Unit Thermistor
Cause/Action
1. Remove the jammed paper.
J414 is connected correctly.

2. Clear the history at the NVM then turn the power OFF and ON.
3. Check whether an out of spec paper is being used. If no problem is found, replace the Fusing Unit.
(PL 7.1)
After replacing, enter CE Mode, go to Printer Diag > Parameter > Life > Fusing Unit Print Count /
Fusing Unit Time Count and initialize the Life Counters.

010-397 (06h) Warm Up Time Fail

BSD-ON:CH10.3,CH10.2
When transitioning from the Wait state, the specified Temperature is not reached within the specified
time.
NOTE: . This Fail may occur when the temperature in the installation environment is low (10 degree C or
lower)
Cause/Action
1. Turn the power OFF and ON.
2. Turn OFF the power and check the following:
• Is the Power Supply voltage above 10% of the rated value? Occurs if the voltage is low.
• The Fusing Unit for improper installation
• The Drawer Connector between the Fusing Unit and the Main Unit (DP/DJ600) for broken/bent
pins, foreign substances, burns, and etc.
• Disconnection, shortage or contact failure of wire between Fusing Unit
P2.
• Disconnection, shortage or contact failure of wire between Fusing Unit
PWB P414.
3. If no problem is found, replace the following parts in sequence:
• Fusing Unit (PL 7.1)
• LVPS (PL 18.3)
• DRIVE PWB (PL 18.2)
• ESS PWB (PL 18.2)
4. After replacing the Fusing Unit, enter CE Mode, go to Printer Diag > Parameter > Life > Fusing Unit
Print Count / Fusing Unit Time Count and initialize the Life Counters.

010-397 (07h) Fusing Unit On Time Fail

BSD-ON:CH10.3,CH10.2
The Heater Rod stayed On after the specified time has passed.
Cause/Action
1. Turn the power OFF and ON.
2. Turn OFF the power and check the following:
• The Fusing Unit for improper installation
