Uncalibrated (Factory Default)
Returns the media configuration to its factory default settings for calibration. You may want to use this option when you accidentally calibrate the proofer with the wrong media loaded.
Last Calibration (Expired)
Returns the media configuration to the settings for its last calibration, and the calibration status becomes expired. You may want to use this option when you calibrated a proofer with clogged nozzles and want to redo the calibration after correcting the proofer.
