5.Press the Left End “slow” or “fast” Up button to lower the rail until the gauge can move in and out with slight friction between the carriage and platen.

6.Insert the gauge under the user end of the carriage to see if one side of the carriage is lower than the other.

7.If one side is lower, calibrate the higher side down to match the lower side.

8.Manually move the carriage to the user-end of the platen and recheck the calibration on both sides of the carriage.

9.If one side is lower, calibrate the higher side down to match the lower side.

10.Recheck the calibration for both sides three times.

The head height will change slightly for the service end after the user end has been adjusted. Recheck the calibrations for both side and adjust as necessary. Rechecking calibra- tion three times on each side is usually sufficient.

11.Press ! (Proceed) to save the calibration.
