When the developer initial setting is successfully completed, the machine stores the calculated Vt as Vtref. The Vtref is used as a reference the next time the machine performs an initial developer setting.
SC360-01 through -04 appears if the results of step 3 are as follows:
The 
count is equal or exceeds the threshold (6480 [counts]).
The 
count does not match the target threshold (5800 – 6380 [counts]) three times consecutively.
Process Control and MUSIC are forcibly done after developer initial setting when a PCDU is replaced.
7.6.3 MUSIC (AUTOMATIC COLOR REGISTRATION CORRECTION)
Correction Timing
The machine creates correction patterns, measures the image position by reading the correction patterns, and corrects the writing position.
