- Set [Periodical Adj. Execution] to [ON]
- Set [Adjustment Execution Timing] to [During Job Runs]
- Set [Adjustment Interval] to [ON]: 1,000 sheets
When the periodic adjustment is set, manual adjustment is not required; however, if you want to update the adjustment value according to the work conditions, perform [Color Density Manual Control]. For details, refer to section 4 in "Recommended Settings".

Set [Synchronize with Image Diagnosis (AQA)] to [ON] with [Package Color Auto Adj.]. You can collectively adjust the items related to the image stability.
It is recommended to perform [Package Color Auto Adj.] at least once per day.
With [Synchronize with Image Diagnosis (AQA)], you can select the items for adjustment to be performed automatically after performing [Image Diagnosis].
For details about [Image Diagnosis], refer to [Image Diagnosis].
