Gradation color for konica 0 series
To calibrate color accuracy and fix color shifts on a Konica Minolta bizhub 0-Series machine (such as the C250i or C300i), tap the Utility icon on the home screen and log into Administrator Settings. Navigate to Maintenance -> Quality Adjustment -> Gradation Adjustment. Select the specific mode you wish to calibrate (such as Copy or Print) and tap Prior Adjustment to run an initial internal stabilization cycle. Next, select your paper tray and press the physical Start button to print a test calibration pattern. Place this printed pattern face down on the scanner glass, aligning it to the top-left index mark, and press Start. The machine will automatically scan, analyze, and correct its color gradations; tap OK to save.
