4.1.1 SUMMARY
There are 4 levels of service call conditions
Level
Fusing unit SCs shown on the operation
panel. The machine is disabled. The user

These SCs are shown on the operation
panel. To reset these SCs, turn the operation

These SCs are shown again if the error

NOTE: 1) If the problem is in an electrical circuit board, disconnect then connect
the board connectors again before you replace the PCB.
2) If the problem is a motor lock, check the mechanical load before you
replace a motor or sensor.
3) When a Level A or Level B SC occurs while the machine is in the SP
mode, the SC number will not be shown. If this occurs, check the SC
number after the machine goes out from the SP mode. This does not
include Level B codes.
4) Many SC codes contain more than one level (SC303-1, SC303-2,
SC303-3, and others). Some SC codes can show a "-1", even if there is
only one level.
