Rev. 1.0 - 23 -LD630D/LD640D5-4 Media CalibrationThis printer has been designed to recognize the gaps with most print papers, butsometimes it may not recognize the gap and keep feeding paper if a special type of paperis used. In this case, run Auto Calibration function so that the printer can recognize the gap.Oki Data printer provides various media calibration methods in order to accommodatevarious special paper types.5-4-1 About media calibration• This function is for adjusting the sensitivity of the paper detection sensor for accurateprinting position control and measuring actual length of paper.• Sensor sensitivity adjustment- The purpose is to detect the identifier (gap/black mark/groove) of installed label• Paper length measurement- Accurate length is required to rotate the printing orientation.- The purpose is to detect the change of paper type.5-4-2 When is media calibration required?• When the printer is installed first time• When the newly installed paper is a different paper type• When printer position is not accurate or printer does not stop in the right position5-4-3 How to perform media calibration• The following four methods of media calibration can be used depending on theconditions.- Smart Media Detection- Gap Sensor Auto Calibration Mode- Black Mark Sensor Auto Calibration Mode- Manual Calibration Mode• Why are several calibration methods provided?- Multiple labels should be scanned for media calibration and more accuratesensitivity calibration can be performed when more labels are scanned.- The number of labels to scan for sensor sensitivity adjustment depends on variousconditions such as label paper material, color, surface status, thickness, gap length,pre-printed pattern, etc.- Four different media calibration modes are provided for compromise betweenprevention of excessive use of paper and accuracy of sensor sensitivity adjustment.- Smart media detection mode that allows for adjustment of sensitivity with minimumamount of scanning should be good enough for most cases with general labels.- Try various methods in order of Smart Media Detection  Gap Sensor AutomaticCalibration / Black Mark Sensor Automatic Calibration  Manual Calibration Mode.
