To run a color calibration on a Konica Minolta bizhub C550i or C650i, press the Utility key on the home screen and select Administrator Settings (log in with your admin password). Navigate to Maintenance ->Quality Adjustment -> Gradation Adjustment. Select the print type you want to calibrate—such as Copy or Print—and tap Prior Adjustment to run an automated stabilization loop.
Next, select your desired paper tray and press the physical Start button to print a test pattern sheet. Place this pattern sheet face down on the flatbed scanner glass, aligning it carefully to the top-left corner marker, and press Start to scan it. The machine will analyze the scanned image and automatically balance its color gradations; tap OK to lock in the new settings.
