Automatically re-adjust the toner density control threshold of Mid High Speed, Medium Speed, and Low Speed.
This function prevents margins from being covered or toner from scattering due to unstable toner density.
Press [Start] to automatically start adjustment.
After adjustment was completed, the adjustment values of yellow, magenta, cyan, and black are displayed individually.
To cancel confirmation, press [Stop].
Even if you press [Return] without pressing [Stop] after [Start], the display does not move to the previous screen.
