Error status of the most recent calibration session. eNoError(1) - The calibation was successful. eUnknownCalibrationError(2) - An unknown error occurred. eScannerFeederEmpty(3) - The feeder contained nothing to scan. eLowMemory(4) - Insufficient memory available to complete the calibration. eWriteFailed(5) - Write to NVRAM failure. eScannerBusy(6) - Scanner is busy. Detailed information about the cause and remedy for each error should be documented in the device POS. Additional information: This object was originally defined for use on HP LaserJet 1100. We are proposing the new enums number 7-9. Note: Option 9 would only be set during a factory calibration to indicate that at least one pixel was not correctable by the digital calibration factors.
