SC Table Key

SC codes are assigned a level of severity (A, B, C, D) based on the table below. These letters appear in the 3rd column of the SC tables below.

Level	Definition/ Reset Procedure
A	This is a fatal error. The machine is disabled due to a problem in the fusing unit. The operator cannot operate the machine. The machine requires immediate servicing by a service technician. After solving the problem, [FusingSCReset] must be executed to release the machine for normal operation.
B	Only the function that uses the defective unit is disabled. The SC code is shown in the message on the Status Panel. Cycle the power OFF/ON.
C	These SC codes are not shown. They are logged internally. Check the SC error log.
D	The SC code is shown in the message on the Status Panel. Cycle the power OFF/ON. The SC code will be shown again if the error repeats.

Before deciding to replace a PCB, disconnect the board connectors, and then connect them again. This is to make sure that the problem was not caused by a bad or loose connection.
