The imageRUNNER can display random E733 error code with different subcodes such as 0001, 0002 and 0010. Simply upgrading System Software to version 31.06.02 for the 6000 Series and 31.06.03 for the 8000 Series can help resolve these codes.
Replacing Main Driver PCB (FM4-1083-000) has resolved the issue, but in some instances the Main Driver PCB and Relay PCB (FM4-1086-000) had to be replaced at the same time.
