Set the neutralization voltage of the 1st transfer belt for yellow, magenta, cyan, black, and special individually.
You can adjust the AC and DC voltage values of the 1st transfer neutralization pole to improve image noises such as ripples and photoconductor memory.
[Condition1]: Increases the AC voltage. This improves the occurrence of ripples.
[Condition2]: Increases the DC voltage. This improves the occurrence of photoconductor memory.
