Common Functions
Auto Gray Calibration (for Copy)
Auto Gray Calibration (for Print)
Copy Calibration by Screen
Printer Calibration by Screen
Performs automatic grayscale correction.
For copying, adjust with [Auto Gray Calibration (for Copy)]. For printing, adjust with [Auto Gray Calibration (for Print)].
You can use [Copy Calibration by Screen] and [Printer Calibration by Screen] to perform even higher precision
adjustment of each mode.
The machine prints a test patch, the test patch is scanned, and the grayscale 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 gray 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
adjustment.
Follow the instructions in the message to perform density smoothing.
If there are no problems after adjustment, perform "Auto Gray Calibration (for Copy)" and "Auto Gray 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).
• Before executing Auto Gray Calibration, check to see if the registration adjustment is correct.
If the registration adjustment is not correct, perform "Registration Adjustment."
• If the grayscale is still off after performing Auto Gray Calibration, repeating Auto Gray Calibration once again may improve
the grayscale.
If the intensity deviation correction does not resolve the intensity deviations, repeat the correction. This may suppress the
deviations.
To repeat density smoothing, you can either start from the beginning, or press the [Back] button after performing smoothing
the first time.
