4. Troubleshooting
4) Scanner Locked / #U1-2115 error
•
Symptom
: Paper stops between the ADF roller and the registration roller of the ADF and a paper jam occurs.
•
Cause
: All 24V channels output voltage is off (24V output voltage is nearly 0V) and 5V channels output is normal.
•
Troubleshooting
1) Check all 24V output channels (24VS1, 24VS2, 24VS3, 24VS4) whether 24V voltage comes out or not.
2) If 24V voltage doesn’t come out, check ‘24V on/off signal pin’ on the main board.
a) The voltage at ‘24V on/off signal pin’ is 0V. → Main board and signal is normal.
b) The voltage at signal pin is 4~5.3V → Main board and signal is abnormal.
3) If the main board and signal is normal and all 24V output channels are nearly 0V, check other parts( i.e. Fuser,
motor, scanner harness, etc.) driven by 24V voltage before replacing the SMPS.
4) If the main board and signal is normal and just one or two or three 24V output channels are nearly 0V, inspect some
harness from abnormal 24V output channel before replacing the SMPS.
5) If the main board and signal is abnormal and all 24V output channels are nearly 0V, inspect the harness, connector
and main board.
