Common Functions

Auto Colour Calibration (for Copy)/Auto Colour Calibration (for Print)

Performs automatic colour correction when the colour is off.
For copying, adjust with [Auto Colour Calibration (for Copy)]. For printing, adjust with [Auto Colour Calibration (for Print)].
The machine prints a test patch, the test patch is scanned, and the colour is automatically corrected.
After the [Execute] key is tapped and a test patch is printed, a message appears prompting you to begin automatic calibration.
Follow the instructions in the message to perform colour adjustment.

Density Smoothing Adjustment

If uneven density occurs in a copy and others, use this function to smooth the density.
The uneven density is automatically corrected by scanning a test patch that you print.
After the [Execute] key is tapped and a test patch is printed, a message appears prompting you to begin automatic calibration. Follow the instructions in the message to perform density smoothing.
If there are no problems after adjustment, perform "Auto Colour Calibration (for Copy)" and "Auto Colour Calibration (for Print)".
To return the adjusted values to their factory default state, tap [Return Density Smoothing Adjustment Value to Defaults]. If you tapped [Return to the Defaults], perform adjustment of the density that you want to readjust (medium density in the default mode).
