SETTING MODE►SYSTEM SETTINGS 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. If the grayscale is still off after performing Auto Gray Calibration, repeating Auto Gray Calibration once again may improve the grayscale. 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 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). Factory default settings: Middle If the intensity deviation correction does not resolve the intensity deviations, repeat the correction. This may suppress the deviations. To repeat the correction, start over the procedure from the first step, or tap the [Back] key after going through the correction procedure. 9-212
